Title: Geographic Variation in Gene ic and Meristic Characters of Coastal Cutthroat Trout (Oncorhynchus clarki clarki). Abstract approved: Redacted for privacy H. Reeves Understanding how populations geographic and temporal scales is fu conservation strategies. I examined t characters of coastal cutthroat trout approximately 1,400 fish sampled fr range (northern California to Prince based on general biogeographical be ithin a species interact across various idarnental to developing appropriate ie geographic variation in genetic and meristic )ncorhynchus clarki clarki) based on m 54 populations spanning their distributional Villiam Sound, Alaska). Four geographic areas, ndaries largely driven by Pleistocene glaciation, were used to examine re onal patterns of population structure. Across their range, the population structure f coastal cutthroat trout was that of many diverse local populations. Populatioi s exhibited extensive variation in meristic characters across their range. Regiori 1 clustering of populations from the southern portion of the range contrasted with opulations from the central and northern portion of the range which did not e thibit geographic concordance. In addition to the strong phenetic affinity of the southc n populations, the intra-regional differences among populations in the southern n gion was greater than that observed in the other regional areas. Analysis of genetic p pulation structure based on 30 enzyme encoding loci revealed geographic c ncordance of populations in the northern and southern regions of the range with ii t le geographic concordance in genetic structure from populations in the central regic s of the range. Throughout the range, isolationby-distance (IBD) was detected at a r gional scale (<800 km) and was strongest in the northern and southern regions. T1 e primary genetic structure of coastal cutthroat trout populations occurred at the mdi ridual stream level, and there was genetic affinity among populations at a regional scale. The strong geographic concordance and inter-regional divergence of meristic characters exhibited by the southern populations was consistent with other ecological studies that have found that peripheral populations tend to be genetically and morphologically divergent from central populations and morphological characters are expected to diverge more rapidly in isolated populations than gene frequencies. These data suggest that compared to other species of Pacific salmon and trout, coastal cutthroat trout are characterized by many smaller, genetically diverse local populations that act in a more independent, isolated nature over short time frames (<100 years). © Copyright by Thomas H.

Local populations (i.e., stocks) of Pacific salmon and trout (Oncorhynchus spp.) are reproductively isolated in space and time and have evolve4 in response to both regional and local environmental conditions. This concept was formalized by Ricker (1972) to define a stock, his adaptation of the biological species concept of Mayr (1942; 1963). Thompson (1965) recognized the importance of local environmental conditions when he wrote "each stream or lake has its own extremely complex characteristics, and if salmon live in one of them we find these salmon are adapted in an equally complex way to that environment." More recently, Taylor (1991b) found examples of local adaptation in salmonids on broad and micro-geographic scales although most evidence was circumstantial. There is now increasing evidence that local adaptation does occur in Pacific salmon and trout (Wood 1995). This stock concept is widely used in the management of Pacific salmon and trout. Designation of a stock was initially based on morphological, behavioral, and physiological features. Before the advent of techniques to describe molecular genetic variation among populations, W. F. Thompson (1959; 1965) suggested that conservation efforts for Pacific salmon should focus on local populations. More recently, genetic data have been used (Utter 1991). Now stocks are being defined more precisely as local populations with the use of genetic data (Booke 1981). Interaction among populations of a particular species is a critical factor to understand when developing management and conservation plans for Pacific salmon 2 and trout. The large intra- and inter-specific variability of life history characteristics of Pacific salmon and trout (Groot and Margolis 1991) have evolved, in part, because of diversity of environments inhabited by these fish. In North America Pleistocene climates and landscapes influenced the distribution of freshwater biotas (Avise 1992). The range of Pacific salmon and trout has been greatly influence by large scale processes such as glaciation and volcanism (McPhail and Lindsey 1986) and smaller scale processes such as fire and flood (Benda 1994). Bayley and Li (1992) believe that species possessing polymorphic attributes (e.g., iteroparous and semalparous life histories, anadromous and nonanadromous life histories) are buffered against environmental uncertainty. Attempts to establish or reestablish populations of Pacific salmon and trout, especially those with more variable life history types such as sockeye salmon (0. clarki), nerka) and coastal cutthroat trout (0. clarki have not been successful, suggesting that some adaptation for the local environment has occurred. The lack of success in efforts to establish or reestablish Pacific salmon and trout to suitable habitat suggest that the plasticity observed in Pacific salmon and trout is adaptive (Healey and Prince 1995). The diversity and availability of habitat may not only be important to provide avenues for movement among populations, but may also provide opportunities for the expression of phenotypic and genetic variation. With an increasing amount of genetic data available to geneticists and resource managers, the task of defining groups of populations became more difficult because these data indicated that population structure was more complex than previous data indicated (e.g., life history traits) and movement of individuals among populations was occurring. The fundamental unit (e.g., demes, randomly mating populations, local populations) identified by geneticists is no longer the same unit (e.g., stock) that was defined prior to the use of genetic data and theory (Currens 1997). The concept of "metapopulations" by Levins (1969) provides perspective for examining spatial structure of populations. A metapopulation can be thought of as a population consisting of many local populations that are connected by the movement of individuals among the local populations. These local populations go through a process of extinction and then recolonization from elsewhere within the metapopulation (Gilpin 1991). The concept has much in common with dynamic theory of island biogeography (MacArthur and Wilson 1963; MacArthur and Wilson 1967), although MacArthur and Wilson dealt with multi-species communities (Hanski and Simberloff 1997). Pacific salmon and trout have some component of each population that may stray to non-natal streams (Neave 1958; Quinn 1984; Ricker 1989; Tailman and Healey 1994). This suggests that a metapopulation-type spatial structuring of populations may be useful for conservation and management of Pacific salmon and trout. Movement of individuals among populations (Wiens 1997) depends on the availability of suitable habitat features at various spatial and temporal scales. In this dissertation, I will develop the argument that management and conservation efforts for Pacific salmon and trout must recognize the importance of both genetic and phenotypic variation and that this recognition should occur with an appreciation and understanding of the influence environmental variation has in the persistence of these fish. I present empirical evidence concerning the geographic variation in population structure of coastal cutthroat trout from across their distributional range. Chapter 2 examines the population structure using meristic characters from populations sampled across the distributional range of this subspecies. Chapter 3 examines the population structure of the same populations using genetic characters allele frequencies. With this descriptive information concerning the population structure of these populations, Chapter 4 synthesizes these genetic and meristic data to describe the geographic variation observed in coastal cutthroat trout and lays the conceptual framework for understanding how habitat variability may interact at various spatial and temporal scales to shape the spatial distribution and persistence of populations. 2. MERISTIC CHARACTERIZATION OF COASTAL CUTTHROAT TROUT (Oncorhynchus clarki clarki) ACROSS THEIR DISTRIBUTIONAL RANGE 2.1. ABSTRACT Conservation planning for any species requires an understanding of the interaction among populations across different geographic scales. The use of meristic measures to exam population structure of Pacific salmonids provides a different perspective to recent efforts that have relied heavily on molecular approaches. I examined meristic differences of 1,491 coastal cutthroat trout (Oncorhynchus clarki clarki) from 54 sites across their distributional range using 13 meristic characters. Across their range, coastal cutthroat trout exhibited extensive variation in the meristic characters examined. Populations at the southern end of the distributional range exhibited phenetic affinity despite significant meristic differences within this regional area. In other portions of the range, little geographic concordance in meristic characters was observed. There were no latitudinal dines detected for any of the meristic characters examined. Juvenile fish with intermediate phenotypes consistent with those expected from decedents of coastal cutthroat trout and steelhead hybridization were detected. Despite the large amount of meristic variation observed across their distributional range, when compared to other western trout species, the coastal cutthroat trout populations examined maintained a phenetic affinity. The observation of unique meristic characteristics of southern populations of coastal cutthroat trout at the peripherery of the range is consistent with observations of other species at the margins of their distribution and suggest that these populations may require special consideration in conservation planning. L,-J 2.2. INTRODUCTION Long-term conservation plans for any species are likely to depend on the identification of distinct populations or populations groups and an understanding of the spatial distribution and relationships among populations. This understanding is critical with respect to defining units of conservation concern and for identifying potential demographic constraints to recovery (Esler 2000), for it is these distinct population segments that form the foundation upon which considerations of extinction risk and recovery options are built (Waples 1991; Waples 1995). Fish species typically consist of many geographically localized populations and, to varying degrees, reproductively isolated populations (Taylor 199 ib). This is particularly true for local populations of Pacific salmon and trout (Oncorhynchus spp.) that tend to become distinct from other local populations because of their high fidelity for returning to their natal stream for spawning. Current efforts to construct geographic boundaries of distinct population segments of Pacific salmon and trout (Evolutionarily Significant Units) rely heavily on molecular tools such as protein electrophoresis and DNA analysis (Waples 1991; Waples 1995). These molecular tools provide data that are used to evaluate isolation among populations since it is believed that they reflect levels of gene flow that occurred over evolutionary time scales (Waples 1995). More traditional methods for identifying populations that use morphology and meristic characters for constructing species and population boundaries are used less frequently because they usually require lethal sampling, the characteristics can be substantially influenced by environmental factors, and the methods can be very time consuming. However, these approaches may provide a different perspective on the geographic distribution of populations and a context in which to interpret molecular 7 data. Meristic characters are body features such as vertebrae, fin rays, and scales, that at one time in the evolutionary past correspond to body segmentation; other characters that can be counted are sometimes referred to as meristic even though they have no correspondence with the myomeres (i.e., myomerism) (Strauss and Bond 1990). Meristic characters have been used to examine interspecific differences and intraspecific population structure of many fish species (i.e., species are usually divided into subpopulations across their range). The systematics of western trout has relied heavily on meristic and morphological characters (Behnke 1992). The systematics of trout in the southern Sierra Nevada has been extensively studied with the use of meristics (Evermann and Bryant 1919; Miller 1950; Schreck and Behnke 1971; Gold and Gall 1975; Gold 1977; Gold and Gall 1981). Legendre et al. (1972) used meristic characters and coloring to indicate phenotypic similarities among several species of western trout (Oncorhynchus spp.). Qadri (1959) used spotting pattern, scale counts, and number of vertebrae to distinguish coastal cutthroat trout (Oncorhynchus clarki clarki) and westslope cutthroat trout (0. c. lewisi). Meristics have also been used to examine intraspecific variation in other fish species. Populations of marine species such as black sea bass (Centropristis striata) (Shepherd 1991), Atlantic cod (Gadus morhua) (Pepin and Can 1993; Swain et al. 2001), witch flounder (Glyptocephalus cynoglossus) (Bowering and Misra 1982), American shad (Alosa sapidissima) (Melvin et al. 1992), and yellowfin tuna (Thunnus albacares) (Royce 1964) have been differentiated by meristic characters. Beacham (1985) found differences in vertebral and gill raker counts useful for population identification of sockeye salmon (0. nerka) on a regional basis. Meristic characters have been used to determine population structure among populations of ['I iJ Arctic charr (Salvelinus alpinus) across large regional areas (Dempson and Misra 1983), between different morphs of nonanadromous Arctic chan (Alekseyev et al. 2002; O'Connell and Dempson 2002), and between anadromous and nonanadromous Arctic chan in the same basin (McCart and Craig 1971). No difference between anadromous and nonanadromous Atlantic salmon (Salmo salar) parr were detected within the same drainage based on dorsal, anal, and pectoral fin rays and vertebrae (Riley et al. 1989). Many studies have examined differences among populations of steelhead based on merjstjc characters (Winter et al. 1980; Schreck et al. 1985; Currens et al. 1990). Meristic characters in fish are generally considered to have a genetic basis (Barlow 1961; Leary et al. 1985), but environmental factors can have substantial influence on them (Strauss and Bond 1990) and may modify an individual's meristic phenotype (Beacham 1985). Relatively minor changes in environmental factors during ontogeny can result in significant within species differences in meristic counts (TAning 1952). Efforts to identify populations of fish based on phenotypic variation must consider that differences observed may be environmentally-induced rather than genetically based (Swain and Foote 1999). Leary et al. (1991) found that rearing density had a significant effect on vertebrae and pelvic fin ray counts in rainbow trout, although the differences were minor compared to differences associated with genetic and temperature effects. Blouw et al. (1988) examined the variability of five meristic characters (vertebrae, gill rakers, pectoral fin rays, dorsal fin pterygiophores, and anal fin pterygiophores) of Atlantic salmon over a 10-year period to estimate within and among year variability. Although they found these meristic traits to be remarkably homogenous within cohorts, the temporal variation among years was extensive and persistent. I,; Even with environmental influence, if meristic differences among populations or population groups exist, these measures may be meaningful for understanding population structure (Shepherd 1991; Melvin et al. 1992). Differences may be very useful if they relate to fitness and are subject to strong selection pressure (Swain and Foote 1999). Selection could result in rapid genetic divergence in phenotypic traits among populations faster than neutral genetic differences could accumulate (Swain and Foote 1999). Leary et al. (1991) reported observations based on experiments with rainbow trout, similar to findings of Ali and Lindsey (1974) with medaka (Oryzias latipes), that the magnitude and direction of meristic variation resulting from environmental factors appeared to have a genetic component. Coastal cutthroat trout provide an opportunity to examine the usefulness of meristic characters to understand the distribution and variation of populations in a species of Oncorhynchus. Although few studies have investigated the genetic bases for meristic counts in cutthroat trout (0. clarki spp.), a genetic basis has been shown in steelheadlrainbow trout (0. mykiss spp.) for scale counts (Winter et al. 1980), vertebrae (Winter et al. 1980; Leary et al. 1985), branchiostegals (MacGregor and MacCrimmon 1977), gill rakers (Smith 1969; Leary et al. 1985), and fin rays (MacGregor and MacCrimmon 1977; Leary et al. 1985). Perhaps due to a lack of emphasis in research and management (National Research Council 1996), few data exist concerning the population structure of coastal cutthroat trout populations at regional scales and across its distributional range. Nehisen et at. (1991) concluded that this prevented scientists from delineating coastal cutthroat trout populations in a meaningful way (Nehisen et al. 1991). The coastal cutthroat trout is the most widely distributed subspecies of cutthroat trout (Behnke 1992; Behnke 2002). They occupy habitats ranging from small to large 10 rivers that drain the coastal rainforest between the Eel River, California, and Prince William Sound, Alaska. The unique karyotype in 0. c. clarki indicates that the subspecies has maintained unity across its range and maintained isolation from other subspecies (Behnke 1992). As with other Pacific salmonids, studies have shown that coastal cutthroat trout form local populations. Applying various genetic techniques Campton and Utter (1987) and Wenburg et al. (1998) have found that, within regional areas (<200 km), coastal cutthroat trout show greater differences among populations than other species of Pacific salmonids, In addition, coastal cutthroat trout exhibit a great amount of variation in life-history types compared to other Pacific salmonids. In general, there are two major life history forms, amphidromous' and potamodromous, although life history traits (e.g., freshwater residence, age at sexual maturity) appear to be highly variable between these two forms and among different populations of similar forms (Sumner 1953; Giger 1972; Jones 1977; Johnston 1982). The possibility of hybridization with steelhead exists for many populations of coastal cutthroat trout. Behnke (1992) speculated that in small streams where two species of trout are found, crossbreeding occurs if reproductive isolation (e.g., insufficient space to allow physical separation at spawning) breaks down. The absence of basibranchial teeth in a coastal cutthroat has been thought to be indicative of hybridization with steelhead (Behnke 1992). In addition, Behnke (1992) states that hybrids may also differ in coloration, spotting pattern, and numbers of scales, caeca, and vertebrae. Campton and Utter (1985) used allozymes to identify juvenile fish with intermediate phenotypes consistent with those expected for decedents of 1 Myers (1949) described amphidromous fish migration as movement from freshwater to the sea, or vice versa, for non reproductive purposes, such as feeding; potamodromous fishes migrate wholly within freshwater. 11 coastal cutthroat trout and steelhead. Their results from two Puget Sound streams, the first formal documented observation of hybrids in the wild, led them to suggest that in streams where both species spawn "the production of hybrid offspring may not be uncommon." More recently, many genetic studies have detected the occurrence of hybrids between coastal cutthroat trout and steelhead in the wild (Hawkins 1997; Wenburg et al. 1998; Young et al. 2001). Use of meristics to delineate populations of coastal cutthroat trout may be complicated by the presence of hybrids, however, meristic characters may provide a useful tool to examine the distribution and prevalence of hybridization. In this study, which included coastal cutthroat trout throughout the distributional range of the subspecies, I present a comprehensive description of selected meristic characters, determine the extent of within sample variation, and examine the possibility of among sample differences. Based on these findings, I examine the geographic variation in selected meristic characters and resulting population structure (i.e., the structure of populations across the range). Previous descriptions of the meristic characters of the subspecies have been limited to relatively small sample sizes and populations from localized or regional geographic area. The basis for Behnke's taxonomic description of the subspecies in his book "Native trout of western North America" (Behnke 1992) was his review of several independent regional surveys (Schultz 1936; Snyder 1940; DeWitt 1954; Qadri 1959) that were not uniform in the meristic characters examined and Behnke's own examination of 277 fish from 22 locations (x = 13). Information based on meristic characters may provide additional insight into geographic population structure based on molecular markers and provide an additional tool for identifying the presence of individuals 12 with characters intermediate to those of coastal cutthroat trout and steelhead (e.g., hybrids). 2.3. METHODS 2.3.1. Sample collection and analysis A total of 1,589 coastal cutthroat trout were collected from 55 sites from northern California to Prince William Sound, Alaska (Figure 2.1, Table 2.1). For presentation purposes the sites were numbered based on their location from north to south. Sites were located in estuaries or streams downstream of migration barriers. A sample consisted of individuals identified in the field as coastal cutthroat trout collected from a common site (location). Samples were typically collected over a period of 1 d, although several sites were sampled in more than one year. The average sample size was 29 fish (range: 13 to 56) per site (Table 2.1). Fish were collected by minnow traps, angling, and downstream migrant traps. Attempts were made to sample several size classes of fish (i.e., age classes) from each population. Two samples from hatcheries, Humboldt State University Hatchery, California, and Fall Creek Hatchery (Alsea River), Oregon, were also included in the analysis. After capture, fish were euthanized (tricane methanesulfonate), weighed (g), measured (fork length FL, mm), and a photograph (Ektachrome ASA 200) of the left side was taken. Each fish was tagged with an identification number that was secured to the lower jaw. Tissue samples for a genetic study done in conjunction with this study were collected from large fish (> 200 mm) in the field while small fish were placed directly on dry ice for transport to laboratory where tissues were removed. Tissue samples were taken from right side of fish. Following tissue removal, fish 13 Figure 2.1. Locations where samples were collected and regional groupings for analysis.

Thirteen meristic counts were collected from each fish (Table 2.2). In general, methods followed those of Hubbs and Lagler (1958). All counts were made on the left side of fish. Vertebrae, dorsal fin ptergyiphores, and anal fin ptergyiphores were counted from radiographs. Radiographs were taken with a cabinet x-ray machine (Fixatron 804) on 20.3 cm X 25.4 cm x-ray film (Agfa Structurix CD4, daylight wrapped, industrial x-ray film, ISO 9001) developed with a Kodak RP-OMAT Processor (Model M6B). The shelf height (55.88 cm) and power (25.0 Kvp) were held constant for all fish, exposure time varied with fish size ranging from 30 seconds for small fish (80 mm) to 5 minutes for larger fish (>300 mm). Radiographs were placed on a light table for counting. Vertebrae counts included all vertebra separated by sutures including the upturned or ural centra, but excluding the urostyle. Dorsal and anal pterygiophores were scored as the number of distinct, extended pterygiophores, excluding the anterior short pterygiophore when it was less than half the length of the second most anterior pterygiophore. Pyloric caeca were counted after fish had been transferred to 70% ETOH. All caeca found posterior of stomach were counted after the intestine had been unwound from the stomach and laid out (Hubbs and Lagler 1958; Behnke 1992). A dissecting microscope was used to count caeca from fish < 150 mm. Sex determination was done at the time caeca were counted. Lateral line series counts were made from scales located two scale rows above (dorsal) the lateral line starting at the first row immediately behind the pectoral girdle and the last row being the one crossing the lateral line at the posterior edge of the hypural plate (Strauss and Bond 1990). Scales above the lateral line were Table 2.2. Summary of meristic counts from all samples of 0. c. clarki and fish designated as 0. mykiss from 54 sites. 0.

Mm 0 counted from the origin of the dorsal fin downward along one of the diagonal scale rows to, but not including, the lateral line scale (Hubbs and Lagler 1958). Malachite green stain (1 g stainll0O ml H20) was applied to the scales just prior to counting and a dissecting microscope (6X 40X) was used. The length of the maxillary was recorded on a scale from 0 to 2 (Figure 2.2). If the maxillary did not extend to the anterior portion of the eye, it was recorded as a 0. If the maxillary extended to somewhere between the anterior and posterior portion of the eye it was recorded as a 1, and if the maxillary extended beyond the posterior portion of the eye, it was recorded as a 2. Alizarin red stain (1 g stain/100 ml H20) was applied twelve hours prior to counting paired fins, gill rakers, basibranchial teeth, and branchiostegal rays,. Fish were placed in sealable plastic bags with paper towels saturated with 70% ETOH until counts were made. Counts of paired fins (pelvic and pectoral), gill rakers, basibranchial teeth, and branchiostegal rays were done with a dissecting microscope. Counts of gill rakers were done on the first arch. Separate counts were made of the lower and upper limbs of each arch with gill rakers straddling the angle of the arch included in the count of the lower limb (Hubbs and Lagler 1958). Compressed air directed through a large gauge hyper-dermic needle was used to remove tissue and mucus that often obscured the basibranchial teeth and gill rakers. 2.3.2. Data analysis During the initial stages of screening for data entry errors it became evident that several samples contained 0. mykiss (steelhead or rainbow trout) misidentified as 19 Figure 2.2. Maxillary extension scores for coastal cutthroat trout. 20 coastal cutthroat trout2. In addition, many samples contained individuals with meristic character counts intermediate to counts expected for steelhead and coastal cutthroat trout that were reported in the literature. The observation of counts intermediate to those of steelhead and coastal cutthroat trout would not be inconsistent with hybridization (Behnke 1992). The two characters most commonly used to differentiate between coastal cutthroat trout and steelhead are basibranchial teeth and the maxillary extension (Table 2.3). In addition to these two characters, the presence of a yellow, orange, or red line in the skin folds of the lower jaw is often used as an identifying character of coastal cutthroat trout. Of these three characters, the maxillary extension and the presence of the colored line on the lower jaw are often used for field identification. Meristic counts most useful for distinguishing between steelhead and coastal cutthroat trout are the number of vertebrae and various scale row counts, but these counts are difficult to determine in the field. Prior to analysis, a decision rule was established to identify steelhead individuals and remove them from the analysis. The length of the maxillary and the absence of basibranchial teeth were used to identify steelhead. Individuals with a maxillary extension score of 0 or 1 (maxillary did not extend past the posterior portion of the eye, see Figure 2.2) and an absence of basibranchial teeth were designated as a steelhead. An individual with a maxillary extension score of 2 or the presence of basibranchial teeth was designated as a coastal cutthroat trout. These two characters were not used for subsequent analyses. Since the meristic counts are discrete, analysis of frequency distributions was by contingency j on untransformed data to determine if there were differences in 2 For purposes of this study, all 0. mykiss collected will be referred to as steelhead since all samples were obtained downstream of migration barriers, although some nonanadromous 0. mykiss (rainbow trout) may be included. 21 Table 2.3.

To avoid sparse cells in the j analysis, fish within a sampling site were pooled into five size groups ( 100 mm, 101 200 mm, 201 300 mm, 301 400, > 400 mm). To test for differences in meristic counts among size groups within a sampling site, a sample needed to consist of at least three size groups with five or more individuals. Phenetic affinities and relationships among samples were examined with several multivariate statistical approaches using the eleven meristic characters described previously (see Table 2.2). To determine if differences existed among sampling sites a multivariate analysis of variance (MANOVA) was used with sample site as the treatment variable. The null hypothesis of no significant differences among sampling sites was tested with the Wilk's A. statistic. Data for the MANOVA were transformed using Gower's method of ranging (Sneath and Sokal 1973) where the smallest value for a character is subtracted from each value and the result is divided by the range. Individual meristic characters were further examined with analysis of variance (ANOVA) with each of the 11 meristic characters as a dependent variable. Differences among sampling sites for the median of a given character were tested with multiple comparisons with a Kruskal-Wallis' H test. Range-transformed data were used for the Kruskal-Wallis' H tests with a Bonferoni experiment-wise multiple comparison test to minimize the possibility of type I error. Canonical variates were generated by discriminant analysis to remove correlation among characters and provide a weighted combination of characters that maximized distinction among locations. A canonical score was derived for each row (i.e., individual fish) in which all independent variables values (i.e., eleven meristic characters) were counted. For each population, the mean of the first canonical variate score was calculated, and these means were plotted to examine differences among populations. I used a clustering and an ordination approach to further examine patterns of geographical similarity. An Euclidian distance matrix created from the range-transformed data was used to construct a dendrogram from cluster analyses of pair-wise differences between samples using the unweighted pair-group method with arithmetic averages (UPGMA) algorithm (Sneath and Sokal 1973). A non-metric multidimensional scaling analysis (MDS) (Kruskal 1964a; Kruskal 1964b) was used to create a plot of the locations in a three-dimensional configuration space of the Euclidian distance matrix created from the range transformed data. 2.4. RESULTS 2.4.1. Identification of steelhead Of the 1,589 fish examined, 98 steelhead were identified based on the absence of basibranchical teeth and a short maxillary extension (Table 2.4; Appendix Table A2. 1). In addition, fish with meristic character counts intermediate to that typically found in coastal cutthroat trout and steelhead were also found in the samples. One sample was determined to contain only steelhead (Suntaheen Creek, Alaska, location 4) and was not used for subsequent analyses except as an outgroup. Mean counts of scales in lateral series, scales above the lateral line, and basibranchial teeth of coastal cutthroat trout were greater than mean counts for steelhead (Table 2.4; Appendix Figures A2. 1 2.6; Appendix Table A2.2). The absence of basibranchial teeth was used as a character for steelhead therefore the counts were less by definition. All other mean character counts were less for coastal cutthroat trout than for steelhead. If fish that exhibited only one of the two characters that were used to designate coastal Table 2.4.

The mean count for pyloric caeca was the exception, the mean count for fish with only one of the two discriminating characters was less than the mean counts for both coastal cutthroat trout and steelhead (Table 2.4; Appendix Figure A2.5). Fish designated as steelhead were not used for subsequent analyses. Fish with only one of the two characters used to designate coastal cutthroat trout were kept in subsequent analyses as coastal cutthroat trout. Although one might consider these individuals to be hybrids since all but one of the mean counts were intermediate or similar to either coastal cutthroat trout or steelhead, it is unclear if these fish are hybrids and sampling was not carried out in such a way to adequately address this issue. 2.4.2. Differences in meristic counts between sex and among length groups within sampling locations Significant differences (P < 0.05) were detected for 14 of the 594 comparisons (2.3%) between meristic character counts of males and females within a sampling location. Given the number of comparison tests made (54 samples X 11 characters = 594 tests), the number of significant tests was far fewer than would be expected by chance and therefore males and females within a sampling location were pooled into a single sample. Six samples had sufficient numbers of fish in at least three size groups to test for differences in meristic count among size groups (Fish Creek, AK, location 1; Kadake Creek, AK, location 9; Wolverine Creek, AK, location 11; 27 Throne River, AK, location 15; Bakewell Creek, AK, location 16; and Siletz River, OR, location 42). Only one significant difference (P <0.05) was detected among size groups and meristic character counts within these six locations. Anal pterygiophores (x2 = 19.21, df = 8, P 0.0 14) among size groups at Wolverine Creek, Alaska (location 11), were significantly different. Given the number of comparison tests made (six locations X 11 characters = 66 tests) I assumed that there were no significant differences between size groups in the populations examined. Based on these results, all sizes of fish within a sampling location were pooled into a single sample. 2.4.3. Differences among sampling locations There were significant differences in the meristic counts (MANOVA, Wilks' A = 0.0695, P < 0.001) among all locations (Figures 2.3 2.8). In addition, there were significant differences detected among all locations at each of the 11 meristic characters (ANOVA, P < 0.01). No linear clinal trends with latitude were apparent, although there appears to be a undulating pattern with latitude for all of the mean character counts, being most pronounced with the scale row counts (i.e., scales in lateral series and scales above the lateral line - Figure 2.5). These patterns were not consistent across character types in terms of increasing and decreasing at the same geographical region nor were they consistent in the direction (i.e., greater or lesser values) at the same geographical region.

Location numbers correspond to numbers in Table 2.1. geographically discontinuous locations. Although, there were samples that were most similar to samples from geographically adjacent locations for a specific character. For example, vertebrae counts (Figure 2.4) were similar between locations 1 and 2; locations 6, 7, 8,and 10 were similar. Conversely, locations 1 and 2 were not similar in their mean count of scales above the lateral line, and locations 6, 7, 8, and 10 were not similar in their mean count of scales above the lateral line (Figure 2.5). The total variation accounted for by the first four variates in canonical analysis was 71%. The first variate accounted for 28.1% of the variation and had an eigenvalue of 0.91. The second, third, and fourth variates accounted for 16.0%, 15.6%, and 11.2% respectively (eigenvalues of 0.52. 0.51, and 0.37). The eigenvaiues for these four variates were statistically significant (Wilks' i test). The characters of primary importance in distinguishing between locations in the first canonical variate were scales above the lateral line count (7.56) and pyloric caeca count (-2.80). A plot of the mean of canonical variate I for each location is not unlike several of the plots of mean character scores (Figure 2.9). Locations at the north of the range tend to have higher values for these two characters than locations at the south end of the range while values for the locations in the central part of the distributional range are variable, with locations along the coast of Washington and south to the Umpqua River having values similar to the most northerly locations (locations 32 though 46). The California locations (locations 50 though 55) represent six of the lowest eight values, the other low scores are for Staney Creek, Alaska (west coast of Prince of Wales Island, location 12) and Salmon River (tributary to the Fraser River, British Columbia, location 25). These low scores for the California locations coincide with low counts for the scale row counts, conversely, locations at the northern end of the range tended to have higher scale row counts (Figure 2.5). 35 - I I 0 0 -1 -2 -3 -4 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 Location Figure 2.9. The mean (±1 SE) canonical variate I score for each sampling location based on 11 meristic characters. Location 4 contained only steelhead and was excluded. Location numbers correspond to numbers in Table 2.1. 36 There was a lack of agreement between the populations that tended to be very different in terms of the number of significantly different medium counts in pairwise comparisons for meristic characters (Appendix Table A23) and the pattern observed in the plot of canonical variate I means (Figure 2.9). That is, the samples with the largest number of significant differences did not standout as being very different based on canonical variates generated by discriminant analysis that removed correlation among the characters and provided a weighted combination of characters that maximized distinction among locations. Gines Creek, Alaska (location 3) had the most number of significant different mediums (168, 29% of the comparisons) yet it was not dissimilar to other locations in its geographic area. Since the canonical variate plot was only for variate I, differences in score were heavily influenced by characters that were heavily weighted in the variate (scales above the lateral line and pyloric caeca). Locations with many significant differences in mediums for meristic characters are not captured by the canonical variate unless those differences are for characters that strongly influence the variate (e.g., 106 differences Bakewell Creek, Alaska (16), 101 differences Kirby Creek, British Columbia (28), 106 differences- Stillaguamish River, Washington (29), and 102 differences Winchuck River, Oregon (49); see also Appendix Table A2.3). Locations at the southern portion of the range (locations 50 - 55) differed from populations to the north as measure by canonical variate I resulting primarily from the lower scale row counts for fish in southern populations (Figure 2.5). Conversely, populations at the northern portion of the range tended to have higher scale row counts and therefore higher canonical variate I scores. There was a general trend of decreasing canonical variate I scores from north to south except for 10 of 14 populations that were between the Quillayute River, Washington (location 32) south 37 to the Umpqua basin (location 46) that tended to have canonical variate I scores similar to locations at the north end of the range (locations 1 5 and 7 11). This pattern where counts from locations from the Washington coast and the north and mid-Oregon coast had counts similar to locations to the north was also evident in several of the mean counts of the meristic characters (Figures 2.3 2.8). A regression between mean canonical variate I and latitude (i.e., UTM northern coordinate) exhibited a slight, but significant decrease in value with locations to the south (r2 = 0.115; P = 0.012; Figure 2.10). With the southern locations removed there was no significant relationship between latitude and canonical variate I (r2 = 0.002; P = 0.93). The phenetic affinities illustrated by the phenograin (Figure 2.11) capture the relative distinctiveness of the California locations (locations 50 55) evident in the canoncial variate pilot (Figure 2.9). Five of the seven samples from the Winchuck River, OR, south to Widow White Creek, CA (locations 49 54), and including the hatchery population from Humboldt State University (location 55) clustered together along with Willow Creek, British Columbia (location 23), and formed a distinct cluster from all the other samples (see shaded region of phenogram, Figure 2.11). Moreover, the long branch lengths (i.e., large Euclidian distances) within the shaded region of the phenogram (Figure 2.11) indicate large intra-regional differences among populations at the southern extend of the species' distributional range. That is, the southern populations tended to exhibit phenetic affinity corresponding to geographic proximity in the cluster analysis, but within this regional grouping, the differences among populations were greater than within other clusters. The Willow Creek sample (location 23) exhibited meristic characters similar to those of steelhead and may be a result of hybrids being included in the sample.

Location numbers correspond to numbers in Table 2.1. from Willow Creek, 14 were misidentified (i.e., initially identified as coastal cutthroat trout in the field, but lacking basibranchial teeth and having a short maxillary extension), nine were designated as coastal cutthroat trout, and two could not be assigned since they were missing a count of basibranchial teeth or a measure of the maxillary extension (Appendix Tables A2. 1 and A2.2). The Willow Creek sample had the second lowest count of scales in lateral series (x = 131.8, Figure 2.5, Appendix Table A2.2) and the fifth lowest count of scales above the lateral line (x = 30.0, Figure 2.5, Appendix Table A2.2). These low scores are similar to values for locations at the southern portion of the range, in addition to being similar to steelhead, and appear to be the major feature of this distinct cluster. It is difficult to make many additional inferences regarding phenetic affinities from the phenogram. There are a few instances where geographically adjacent locations show phenetic affinity. A group of locations in the greater Ketchikan, AK, area (Wolverine Creek location 11, Vixen Inlet Margaret Creek (Traitors Cove) 13, 14, Throne River 15, and Bakewell Creek 16) clustered together. The Siletz River (42) and Schooner Creek (41) clustered together as did the Salmon River (25, Fraser River tributary) and Church Creek (29, Stillaguamish River tributary). As in the cluster analysis, with the exception of regional structuring at very large spatial scales that separated out the southern populations, only weak geographic concordance was evident in the MDS analysis. The phenetic affinity for the southern locations evident in the canonical variate and cluster analyses was also evident in the multidimensional scaling (Figure 2.12). The stress value of 0.082 of the MDS analysis is considered good, a value of 0.05 would be considered excellent, 0.0 perfect, and 0.2 poor (Kruskal 1964a). This statistic measures the goodness of fit of of the and (Sneath and Sokal 1973). All locatiOns from Jordon Creek, California (location 50) south were 41 0.97 0.41 [II -0.1 -0.7 1.76 Figure 2.12. Multidimensional scaling (dimensions 1,11 and III) of Euclidian distance based on 11 merjstic characters of coastal cutthroat trout from 54 locations. The stress value for this clustering was 0.082. Location 4 contained only steelhead and was excluded. Location numbers correspond to numbers in Table 2.1. 42 grouped together. As in the cluster analysis (Figure 2.11), Willow Creek, British Columiba (location 23), had a phenetic affinity with locations in the southern portion of the range. These southern locations along with Willow Creek formed the most distinctive grouping in the MDS analysis. The first location south of the Rogue River, the Winchuck River, Oregon (location 49) shared some phenetic affinity to southern group to locations (i.e., is adjacent in MDS space). With the exception of the Rogue River sample (Iron Creek, location 48), the distribution of these southern populations is consistent with other salmonid studies that have found a zoogeographic break in the area around Cape Blanco, Oregon (Hatch 1990; Weitkamp et al. 1995; Busby et al. 1996). The MDS analysis reveled phenetic distinctiveness of the Alsea hatchery (location 44) sample and the Gines Creek (location 3) sample. The Alsea hatchery sample exhibited the largest SE of the mean of canonical variate I of all the samples (Figure 2.9). 2.5. DISCUSSION Significant variation of meristic characters was found among 54 sample sites consisting of 1,491 individual coastal cutthroat trout from across their distributional range. This survey was based on samples collected over a five year period, providing a snap shot of the meristic variation that existed from 1992 to 1996 and minimizing temporal environmental effects that may have large influences on salmonid production (Pearcy 1992) and are quite dynamic across the range of coastal cutthroat trout (Pearcy 1997). In the most comprehensive survey previous to this work, Behnke (Behnke 1992) suggested that anadromous coastal cutthroat trout were morphologicaily similar throughout their range and exhibited no clinal variation in characters between northern and southern populations. Behnke's review was based on his collections along with 3] data from others (Schultz 1936; Snyder 1940; DeWitt 1954; Qadri 1959) that were collected over many years. The number of meristic elements in the phenotype can be influenced by the magnitude, timing, and duration of environmental factors (Beacham 1985), even minor changes in temperature, salinity, light, and dissolved gasses during ontogeny can result in significant differences in meristic counts within the same species (Tâning 1952). The mean values for the various characters are similar to those reported by Behnke (1992), although Behnke does report some values that were much different than observed in my study. For instance, the highest number of basibranchial teeth observed by Behnke was a mean of 29 from Lake Sutherland, Washington, about twice as many as he found in any other sample. The highest mean count of basibranchial teeth from my study were 20.4 from Throne River,'Alaska, 20.6 from Yakoun River, British Columbia, and 22.4 from Staney Creek, Alaska. The mean count of 144.9 for scales in lateral series is at the lower end of the range of 140 to 180 reported by Behnke (1992). Although some of the individuals in my sample may have been hybrids based on the absence of basibranchial teeth, the mean count with only individuals with basibranchial teeth was 146.8, still on the low end of the range reported by Behnke. There was no latitudinal dine detected for any of the meristic characters examined. This is in contrast to the general pattern of an increasing number of elements for most meristic characters in fish with increasing distance from the equator (Hubbs 1926; Tâning 1952; Beacham 1985). The number of elements for a particular meristic character is influenced by the development rate of the embryo with longer developmental times resulting in a greater number of elements (Hubbs 1926), northern areas of the coastal cutthroat trout range experience cooler rearing temperatures than southern areas and therefore would he expected to have higher numbers of elements. !YiI Slower developmental rates in salmonids have been associated with higher numbers of vertebrae in embryos (Kwain 1975; Beacham 1985). Shepherd (1991) described meristic characters as phenotypic expressions of environmental conditions during egg and larval development, adequate temporal and spatial heterogeneity form the basis of population differentiation using these characters. In my study, several of the individual characters exhibited a slight clime across the range that was interrupted by counts from the Quillayute River, Washington (location 32) south to the Umpqua basin (location 46). Counts from these locations along the Washington coast south to the mid-Oregon coast were similar to the higher mean counts found at the northern portion of the range. Significant differences were found among all populations examined in this study, although phenetic clustering and ordination exhibited very weak geographic concordance. Meristic characters were not able to describe intra-specific population structure at small spatial scales. With just a few exceptions such as the Ketchikan area of southeast Alaska (locations 11,13 16), populations from the Winchuck River south (locations 49 55), Schooner Creek and Siletz River (locations 41 and 42), and the Salmon and Stillaguamish rivers (locations 25 and 29)), there was little phenetic affinity even among adjacent locations based on the cluster analysis and MDS analysis of Euclidian distances. Others have found meristic characters to be useful for delineating population structure in salmonids at relatively small scales (Smith 1969; Dempson and Misra 1983; Schreck et al. 1985). The general lack of geographic concordance in this study may be a result of the large geographic range surveyed that encompassed a large range of environmental conditions and gradients. My findings do suggest that caution should be used when inferring population structure based on samples from spatially small, 45 local, or intra-regional studies to larger spatial scales. At the spatial scale surveyed in this study, meristic characters provided information about population structure at only large spatial scales. The populations at the southern portion of the range had a relatively strong phenetic affinity. This did not appear to be a result of an overall latitudinal dine across the range, but a result of coastal cutthroat trout at the southern extent of the range having similar meristic characteristics. The clustering of locations observed for the southern Oregon and Northern California locations was consistent with findings from other studies and status reviews of anadromous salmonids that detected a zoogeographic break in the area around Cape Blanco, Oregon (Hatch 1990; Weitkamp et al. 1995; Busby et al. 1996; Johnson et al. 1999). Although my results are not inconsistent with these previous studies, another interpretation may be that there is a zoogeographic break for coastal cutthroat trout in the region between the Rogue River and the Klarnath River. The separate clustering of sampling locations south of the Winchuck River (locations 50 55) and the inclusion of the Winchuck River (location 49) and Rogue River samples (location 48) with a larger non-southern group in the MDS analysis supports this break (Figure 2.12). This is a region of zoogreographic transition. The Rogue River is the southern limit of distribution of the reticulate sculpin (Cottus perplexus), a species in virtually every stream in western Oregon and Washington (Minckley et al. 1986; Moyle 2002), and the Rogue River contains the same saltwater dispersant species that are found in the lower Kiamath (Moyle 2002). Coastal Oregon streams south of the Rogue River (Hunter Creek, Pistol Creek, Chetco River, Winchuck River) do not have inland fish species like those found in the Rogue and Kiamath systems (Minckley et al. 1986). The Kiamath drainage supports many unique fishes, particularly above Kiamath Falls where the fish fauna is much different than that found in the lower Kiamath River, and both the Sacramento and Columbia rivers (Minckley et al. 1986). No other patterns of phenetic affinity at a regional scale were detected from my samples of coastal cutthroat trout. The usefulness of meristic characters to delineate regional clusters has been observed in other studies. Beacham (1985) found similar results for sockeye salmon collected from North America; differences in vertebrae number and gill rakers were only useful to identifying stocks of sockeye salmon on a broad regional basis. For western trout species, meristics has been used for inter-specific comparisons and systematics studies (Schreck and Behnke 1971; Gold and Gall 1975; Gold 1977; Gold and Gall 1981). Although significant differences among locations for meristic characters were detected in my study, coastal cutthroat trout maintained a phenetic affinity when compared to other species of western trout based on nine meristic characters that included anal pterygiophores (anal fin rays for historical counts, dorsal pterygiophores (dorsal fin rays for historical counts), vertebrae, scales in lateral series, pelvic fin rays, pectoral fin rays, branchiostegal rays, total gill rakers on the first arch, and pyloric caeca; Table 2.5). Coastal cutthroat trout from this study grouped together when the MDS scaling was used to compare them to steelhead from Alaska (Suntaheen Creek, Alaska, this study), 0. mykiss from the Deschutes River (Currens 1987), 0. gila (Gila trout (Miller 1950)), 0. chrysogaster (Mexican golden trout (Needham and Gard 1964)), 0. aguabonita (California golden trout (Gold and Gail 1975)), 0. apache (Apache trout (Miller 1972)), 0. c. pleuriticus (Colorado cutthroat trout (Gold et al. 1978)(Gold et al. 1978)), and Redband (Gold 1977). The 0. mykiss samples grouped together and exhibited some phenetic affinities with the Colorado cutthroat trout, Apache trout, and California golden trout (Figure 2.13). The Gila trout, Mexican golden, and Redband samples were separate from the other clusters and were much different than the 0. mykiss, Colorado cutthroat trout, Apache trout, and California Table 2.5.

Both figures are the same, but figure has been rotated. The stress value for this MDS was 0.067. Location 23 is a coastal cutthroat trout populations from Willow Creek, British Columbia (this study). golden trout. In summary, despite the large variation in meristic characters observed within and among coastal cutthroat trout samples surveyed in this study, coastal cutthroat trout remained a cohesive group when compared to other western trout species in MDS analysis of nine meristic characters. Locations sampled from regional areas that provided refuge during the Pleistocene glaciation showed little phenetic affinity for geographically adjacent locations, but areas that showed high pheneitc affinity for geographically adjacent locations (i.e., Ketchikan area; Wolverine Creek - location 11, Vixen Inlet 13, Margaret Creek (Traitors Cove) 14, Throne River 15, and Bakewell Creek 16) may represent similar recolonization events or reflect very similar environmental conditions resulting in similar meristic characters. Gines Creek, Alaska (location 3), may represent a relatively young population and the uniqueness of these fish based on the meristic characteristics may be a result of a recent colonization. Gines Creek fish had the highest number of significantly different medium counts (number of significantly different medium counts = 168), the next most unique was the Humboldt State University Hatchery (location 55) with 122 significant different medium counts. In addition, Gines Creek clustered on the margins of the coastal cutthroat group when compared to other western trout species with the MDS ordination (Figure 2.13). Patterns found along the Washington coast south to the mid-Oregon coast may be a result of Columbia River and its influence during Pleistocene glaciation or an artifact of the many years of hatchery releases; including the introduction of hybrids, that has occurred in this region (Johnson et al. 1999). The two hatchery samples had the highest variation for canonical variate analysis and the second (Humboldt State University Hatchery, location 55, 168 significant differences) and seventh (Alsea Hatchery, location 44, 97 significant differences) greater number of significantly different mean counts. The Humboldt State University Hatchery samples had the highest phenetic affinity with Widow White Creek (location 54), a previous source for the hatchery's broodstock (E. Loudenslager, Humboldt State University, personal communication). These two sites were similar to the sample from Willow Creek, British Columbia (location 23), that included many individuals with one of the two characters used to distinguish steelhead. These samples exhibited some phenetic affinity for steelhead samples (Figure 2.13). Hatchery production of anadromous coastal cutthroat trout has been focused on providing sport fishing opportunities and has occurred primarily in Puget Sound, Grays Harbor, the Lower Columbia River, and the Oregon coast (Johnson et al. 1999). Hartman and Gill (1968) concluded that the introduction of hatchery coastal cutthroat trout in British Columbia streams that had occurred as early as 1930, occurred in streams that where coastal cutthroat trout were all ready present and were generally not successful and, therefore were unlikely to have influenced the distributional characteristics of coastal cutthroat trout in the areas they surveyed. As early as 1912 the State of Washington reported the release of cutthroat trout and steelhead hybrids (cutthroat cross trout) in the Nisqually River, Puget Sound, Washington (Riseland 1912). Crawford (1979) reviewed the history of trout brood stocks in Washington and reported that returns from an anadromous coastal cutthroat trout program started in the 1950s were poor and in response, brought in Alsea River hatchery fish followed by crosses with steelhead in the late 1 960s. It appears most of these efforts to establish high return rates with hatchery fish were unsuccessful, it is unclear how the release of hybrid coastal cutthroat trout and steelhead may have influenced the native populations. For several of the meristic characters, the presence of hybrid fish, particularly of hatchery origin, may explain the undulating pattern that disrupts what might be a clinal 51 change in counts that was observed for many of the locations along the Washington coast south to the mid-Oregon coast. This would explain the increase in anal pterygiophore counts and perhaps vertebrae counts in this region, but the direction of the deviation of all other counts in this region are not consistent with this scenario. Specifically, both scale row counts are higher in this region where I would suspect lower counts if hybrids or steelhead were included in the samples. The use of meristic characters proved useful for the identification of steelhead misidentified as coastal cutthroat trout. In most cases, the steelhead that were misidentified as coastal cutthroat trout were small, less than 75 mm in length. Character traits used in the past (maxillary extension, basibranchial teeth, and presence of a yellow, orange, or red line in the skin folds of the lower jaw) appear to be reasonable for the field identification of these species when fish are greater than 75 mm in length. Misidentification of these species could be problematic in other studies where non-invasive samples (e.g., fin clip) are taken for genetic analysis without the collection of voucher specimens to confirm fish identification. The presence in my samples of individual fish that were hybrids between coastal cutthroat trout and 0. mykiss may have occurred since the absence of basibranchial teeth and a short maxillary is likely not diagnostic. Behnke (1992) speculated that although gene flow may occur between coastal cutthroat trout and coastal rainbow trout (i.e., steelhead), reproductive isolation typically does not break down completely and it is uncommon to find a hybrid swarm typically found when interior cutthroat trout species hybridize. Campton and Utter (1985) concluded that a post zygotic isolating mechanism may be contributing to the preservation of species integrity given the infrequent observation of adult hybrids. The clearest example of a population that may have contained hybrid individuals is Willow Creek, British Columbia (location 52 23). Fourteen of the 23 fish in the Willow Creek sample were identified as coastal cutthroat trout in the field, but were latter determined to be steelhead based on the absence of basibranchail teeth and a short maxillary extension. The mean length of these 14 fish was 65.7 mm. Of the nine fish used for analyses, five had either no basibranchial teeth or a short maxillary extension. In the cluster analysis (Figure 2.11), fish from Willow Creek exhibits no geographic concordance with adjacent locations and clusters with the southern populations (locations 49,50,53,54, and 55) that tended to have several characteristics similar to those of 0. mykiss (e.g., lower scale row counts, higher number of vertebrae). The Willow Creek sample had the highest mean count for vertebrae (x = 63.1, Figure 2.4, Appendix Table A2.2) and the lowest mean count of scales in lateral series (x = 131.8, Figure 2.5, Appendix Table A2.2), both counts very similar to those fish identified as 0. mykiss in this study (X = 63.3 vertebrae, x = 124.6 scale in lateral series, Table 2.2). Tn the MDS analysis of coastal cutthroat trout from this study (Figure 2.12), Willow Creek appears on the margins of the cluster of coastal cutthroat trout populations. In the MDS analysis with other western trout species (Figure 2.13), Willow Creek is the coastal cutthroat trout population most closely associated with the group that included 0. mykiss, Colorado cutthroat trout, Apache trout, and California golden trout. The identification of juvenile fish with intermediate phenotypes consistent with those expected from decedents of coastal cutthroat trout and steelhead reported by Campton and Utter (1985) based on allozymes was the first formal documented observation of hybrids in the wild. This led the authors to suggest that in streams where both species spawn "the production of hybrid offspring may not be uncommon." But the existence of hybrids, or at least fish with intermediated characteristics between coastal cutthroat trout and steelhead, in the wild had been observed prior to Campton 53 and Utter's published results. The presence of hybrids between coastal cutthroat trout and steelhead in the wild was suspected as early as 1940, when Professor Roland E. Dimick at Oregon State University observed fish with meristic and morphological characters intermediate to those of 0. c. clarki and 0. mykiss in coastal basins in Oregon. He observed these fish with intermediate characters only where both 0. c. ciarki and 0. mykiss were found, and in 1941 carried out paired matings in the Alsea Fish 1-latchery, Oregon, to confirm his suspicion that these individuals with intermediate characters were hybrids. Two of the key characters used by Dimick were scales in the lateral series and the length of the maxillary extension. Unfortunately the results were never published, and the only records of his work are his field notes with his observations and the results from the hatchery experiment, and a four page summary in the archives at the Department of Fisheries and Wildlife, Oregon State University. Dimick's notes are extremely useful in that he developed a set of 10 "character quantities and their values", based on his field observations and hatcheiy experiments, that he used to determine whether a fish in hand was 0. c. clarki or 0. mykiss. Recently, studies to examine hybridization between coastal cutthroat trout and steelhead using molecular markers have been conducted (Hawk ins 1997; Wenburg et al. 1998; Young et al. 2001; Baker et al. 2002). Genetic studies in conjunction with meristic analysis should provide context to historical surveys and help with the development of methods appropriate for use in the field to provide better identification of coastal cutthroat trout, steelhead, and hybrids (Weigel et al. 2002; Baumsteiger 2002). it is not always possible nor appropriate to collect voucher specimens when working with threatened or endangered species; but when possible, voucher specimens should he taken to confirm field identification. This is especially true in areas where 54 coastal cutthroat trout and steelhead occur, the misidentification or the collection of hybrids could lead to incorrect interpretation of the results. In summary, coastal cutthroat trout exhibited extensive variation in meristic characters across their distributional range with populations at the southern end of the distributional range exhibiting phenetic affinity in spite of rather significant meristic differences within this regional area. My findings are consistent with those of Behnke (Behnke 1992) that there is no clinal variation across the range. The regional clustering of locations in the southern portion of the range is in contrast to findings of Behnke's that coastal cutthroat trout are morphologically similar throughout their range, although coastal cutthroat trout populations formed a cohesive group in MDS analysis when compared to other western trout species, there were significant differences in ineristic characters among coastal cutthroat trout populations surveyed. The populations examined from the northern periphery of the distributional range did not show phenetic affinity, nor did the northern populations exhibit the large amount of within region differences (based on branch length in the UPGMA cluster analysis) in meristic characters that was observed from the locations sampled at the southern periphery of the range. Populations that occupy the periphery of a species' range may occupy areas that are marginal in terms of habitat or ecological conditions in addition to being on the margins of a species distributional range. Peripheral populations at both the northern and southern extent of the range of coastal cutthroat trout are geographically marginal based on spatial distance. The southern populations are also ecologically marginal since they experience different biotic and abiotic environments (i.e., Kiamath Province, etc.) than adjacent populations along the Oregon coast and throughout the range of coastal cutthroat trout whereas the northern populations occupy areas that are 55 similar to conditions throughout a large part of the distributional range. This may explain the unique meristic characters of populations in the southern end of the range and the large within-region variation observed among these southern populations. Coastal basins in Oregon south of, and including the Sixes River, drain the Klamath Mountains and the unique geology that makes up the Kiamath Mountains Geologic Province. Sampling locations from the region include locations 48 to 55. Lesica and Allendorf (1995) reviewed various aspects of peripheral populations and their value to species conservation with special attention to the distinction between marginal versus peripheral habitat conditions. In general, peripheral populations tend to be genetically and morphologicaliy divergent from central populations and that morphological characters are expected to diverge more rapidly in isolated populations than gene frequencies (Lesica and Allendorf 1995). Recently, Channell and Lomolino (2000) found that in contrast to the conventional thinking that predicts core populations persisting and range contraction as a species becomes endangered, most species (of 245 examined) they considered persist in the periphery of their historical geographical range. Although there is no indication that the southern distribution of coastal cutthroat trout has changed over the last century, long-term conservation plans are likely to depend on protection of distinct populations (Lesica and Allendorf 1995). particularly peripheral populations in marginal habitats that may contain high adaptive significance to the species as a whole (Scudder 1989). Habitat that was suboptimal historically along the periphery of a species range may provide valuable opportunities for conservation planning (Channell and Lomolino 2000), for it is in these areas one often finds divergence from central populations (Lesica and Allendorf 1995). For coastal cutthroat trout, the unique meristic characteristics of populations in the southern extent of the range suggest that these populations may be essential to conserve the range of diversity in the sub-species. 57 3. GENETIC POPULATION STRUCTURE OF COASTAL CUTTHROAT TROUT (Oncorhynchus clarki clarki) IN WESTERN NORTH AMERICA 3.1. ABSTRACT I examined genetic differences among 1,413 coastal cutthroat trout (Oncorhynchus clarki clarki) from 54 sites across their distributional range using 30 enzyme encoding loci. Collection sites were located in estuaries or streams downstream of migration barriers from northern California to Prince William Sound, Alaska. Genetic population structure was primarily at the individual stream level. There were differences in the distribution of genetic variation across the landscape although the amount of genetic variation within regions was similar. Geographic concordance of populations at the northern and southern extent of the subspecies range was observed and isolation by distance was evident at regional scales (< 800 km). Compared to other species of Pacific salmon and trout, coastal cutthroat trout are characterized by more diverse local populations that act in an independent, isolated nature. The amount of sub-population genetic structure in my study did not differ among regions, but the strength of isolation by distance differed among regions with the strongest isolation by distance being detected at the northern and southern extent of the range. 3.2. INTRODUCTION An understanding of the spatial distribution of populations of a threatened or endangered species across its distributional range is fundamental to developing appropriate conservation and recovery strategies (Waples 1991; Waples 1995). Fish species typically consist of many geographically localized populations that are, to varying degrees, reproductively isolated (Taylor 1991a). This is especially true for local populations of Pacific salmon and trout (Oncorhynchus spp.) that tend to become distinct from other local populations because of their high fidelity for returning to their natal stream for spawning. Although homing to natal streams appears to be very strong in anadromous salmonids, straying among local populations (i.e., immigration) does occur. The extent to which straying occurs is not well understood, but enough isolation occurs so that differences exist and intraspecific differences may exist among closely adjacent populations. Little is known about the interaction (i.e., migration, gene flow) among populations of coastal cutthroat trout (Oncorhynchus clarki clarki) and the resulting genetic population structure of the subspecies across its range, perhaps due an under emphasis of research and management (Nehisen et al. 1991). Moreover, although declining numbers of coastal cutthroat trout in coastal basins have been suspected for many years, little is known about the status of these populations. Snyder (1940) observed a decline of coastal cutthroat trout in northern California from 1897 to 1940. As early as 1948 it was being suggested that harvest be reduced and programs be initiated to restore and improve habitat in response to declining numbers of coastal cutthroat trout in Oregon (Sumner 1948). Nehisen et al. (1991) stated that few data were available, but existing data indicated that a major decline was occurring, mainly as a result of habitat damage and over-fishing. Coastal cutthroat trout are the most widely distributed subspecies of cutthroat trout (Bebnke 1992; Behnke 1992; Behnke 2002). They occupy habitats ranging from small to large rivers that drain the coastal rainforest between the Eel River, California, and Prince William Sound, Alaska, with a large portion of their range falling within the region often referred to as "Cascadia" (McPhail and Lindsey 1986; Behnke 1992). This region is a highly dynamic environment and episodic changes in Pleistocene climates and landscapes have influenced the distribution of freshwater biotas (Avise 1992). 59 Compared to other regions in North America, there are few native freshwater fish species in this region. McPhail and Lindsey (1986) state the principal reasons for the few number of species are historical and associated with glaciation; at times during the Pleistocene, over three-quarters of the land area of Cascadia was covered with ice. In addition, changes to the environment from logging, harvest, fire, debris removal, barrier removal, out-of-channel water uses, hydroelectric development, and even preservation of "pristine' environments may have affected fish communities (Michael 1983). An understanding of the genetic population structure of coastal cutthroat trout must be considered in the context of its environment for developing appropriate conservation strategies. Catric et al. (2001) found contemporary genetic population structure of brook charr (Salvelinusfontinalis) was influenced by landscape features, although there was substantial variation. At smaller spatial scales (within basins) there was evidence that the contemporary landscape shaped the pattern genetic diversity; but at larger spatial scales (among basins) contemporary landscape features had a minor influence on genetic structuring among basins. The dynamic environment of the Pacific Northwest creates a situation in which local populations may go extinct and habitats must be recolonized. The concept of metapopulations is an useful starting point to consider how local populations interact at various spacial scales to contribute to the persistence of a larger group of populations (Hanski and Gilpin 1997). Although the metapopulation concept is widely invoked in a range of studies and situations (Hanski and Simberloff 1997), its attractiveness for considering how salmonids persist in a dynamic environment are it's two key premises that are populations are spatially structured into assemblages of local breeding populations and that migration among local populations effects local dynamics (Hanski and Simberloff 1997). The position, distribution, and interaction among local populations is considered, this is in contrast to standard approaches in population biology that assume a panmictic population structure. Metapopulations spread the risk of extinction among subpopulations, changes in local environmental conditions can lead to local extinctions with the persistence of a group of populations (i.e., metapopulation) depending on how well the organism can track the shifting spatial locations of suitable habitat (Wiens 1997). Some populations may operate as "sources" and others as "sinks", with subpopulations assuming different roles different times (Stacey and Taper 1992). However, all subpopulations can contribute to the overall diversity (Poff and Ward 1990), stability, and persistence (Rieman and McIntyre 1993). Stray rates may not be static, but may vary spatially and temporally. Environmental and geologic events (e.g., floods, droughts, glaciers) may limit access to natal streams and spawning areas, perhaps resulting in increased straying in the pursuit of other suitable spawning areas. Collections of subpopulations (i.e., metapopulations) of coastal cutthroat trout are connected through local exchange of individuals, and these metapopulations are connected across the distributional range of the sub-species through exchange of individuals. Genetic differentiation occurs when the exchange of individuals or entire populations (i.e., gene flow) tends to produce genetic homogeneity and is sufficient to overcome local differentiation that results from mutation, genetic drift, and natural selection (Slatkin 1987). Wright (1943) introduced the term "isolation by distance" to describe genetic differences resulting from geographically restricted dispersal (Slatkin 1993). In general, isolation by distance (IBD) suggest that genetic differentiation increases with geographic distance. Slatkin (1993) examined IBD in populations that were and were not in equilibrium under dispersal and genetic drift and found that with 61 reasonable sample sizes IBD can be detected. Hutchison and Templeton (1999) summarize the above work and work by others that develop a stepping-stone model of population structure where dispersal is constrained by geographic distance resulting in closely situated populations tend to be more genetically similar, and based on this foundation developed an approach to evaluate the relative influences of gene flow and drift on population structure both within and between regional areas. Such a stepping stone model is appropriate for anadromous salmonids since straying studies have found that there is a decrease in the number of strays with increasing distance from natal stream (Labelle 1992; Quinn 1993; Candy and Beacham 2000). The patterns of genetic variability across the landscape is critical to establishing population units for conservation and may prove more meaningful than clustering techniques and ordination techniques that nnay not be appropriate for defining conservation units for populations that are arranged continuously in space (Diniz-Filho and Telles 2002). Coastal cutthroat trout exhibit a great amount of variation in life-history types compared to other Pacific salmonids. In general, there are two major life history forms, amphidromous3 and potamodromous, although life history traits (e.g., freshwater residence, age at sexual maturity) appear to be highly variable between these two forms and among different populations of similar forms (Sumner 1953; Giger 1972; Jones 1977; Johnston 1982). Amphidromous coastal cutthroat trout, often referred to as anadromous or sea-run, appear to have a high fidelity for spawning in their natal stream (Johnston 1982; Campton and Utter 1987), although fish may enter non-natal streams for reasons other than spawning (e.g., overwintering (Johnston 1982)). Myers (1949) described amphidromous fish migration as movement from freshwater to the sea, or vice versa, for non reproductive purposes, such as feeding; potamodromous fishes migrate wholly within freshwater. 62 Straying (spawning in non-natal stream) is believed to occur at low levels (Giger 1972). Patterns of allelic frequency divergence have been used to provide a description of genetic exchange and the amount of isolation among local geographic populations of salmonids (Allendorl and Phelps 1981). As with other Pacific salmonids, studies have shown that coastal cutthroat trout form local populations across their range. Applying various genetic techniques Campton and Utter (1987), Wenburg et al. (1998), and Wenburg and Bentzen (2001) have found that, within regional areas (<200 km), coastal cutthroat trout show greater differences among populations than other species of Pacific salmonids. Campton and Utter (1987) found that anadromous populations of coastal cutthroat trout within the Puget Sound area of Washington consisted of at least three genetically divergent groups. In addition, Campton and Utter (1987) found divergent allele frequencies for a nonanadromous population that suggested a correspondence between population structure and gene flow. Wenburg et al. (1998) concluded that coastal cutthroat trout were reproductively isolated at the individual basin level and loosely structured at a regional scale that included the Puget Sound and areas of coastal Washington. Moreover, Wenburg and Bentzen (2001) used both tagrecapture information in conjunction with molecular markers (microsatellites) to conclude that independent streams sampled in Hood Canal, Washington, contained distinct populations and that these independent populations formed the fundamental units of coastal cutthroat trout genetic population structure. Their genetic data, that included additional populations from the Puget Sound and Washington coast, were consistent with their tag-recapture/genetic findings from the Hood Canal (Wenburg and Bentzen 2001). 63 Wilson et al. (1985) reported two clonal lines of coastal cutthroat trout from the lower Fraser River, British Columbia, but did not discuss if these represented two different populations, either anadromous, resident, or sympatric populations. In the Coquille River, Oregon, gene flow was found to be as restricted among local populations of resident coastal cutthroat trout as it was between populations in distant tributaries in the same drainage (Currens et al. 1992). They concluded that the observed random genetic differentiation among local populations suggested a history of genetic drift and small population sizes. Besides Campton and Utter (1987), few data are available concerning genetic differences between resident and anadromous forms of coastal cutthroat trout. Other coastal cutthroat trout studies based on allozymes have reported results ranging from mixing of anadromous and nonanadromous populations within a single basin (Zimmerman 1995) to very limited gene flow among populations regardless of the absence of migration barriers (Griswold 1996). Michael (1983) suggested that sympatric populations of anadromous and resident coastal cutthroat trout may exist, but this was based on trapping data and included no genetic analysis. Studies of other salmonid species with anadromous and nonanadrornous life history forms tend to find limited gene flow among life history forms. Birt et al. (1986) used mtDNA to analyze anadromous and nonanadromous populations of Atlantic salmon (Salmo salar) and detected very little genetic differentiation between the two forms. Hinder et al. (1991) found no genetic differentiation between resident and anadromous brown trout (Salmo trutta) from the same locality using electrophoretic techniques. Costello et al. (2003) found that migration barriers were important in structuring genetic variation of bull trout (Salvelinus confluentus) within and between basins. In this study, I examine the geographic distribution of genetic variation of anadromous coastal cutthroat trout across its distributional range to determine if genetic diversity among populations differs regionally, perhaps reflecting historical landscape/environmental features, and to determine the spatial distribution of genetic diversity across the range of the subspecies. 3.3. METHODS 3.3.1. Sample collection and analysis A total of 1,619 coastal cutthroat trout were collected from 55 sites in estuaries or streams downstream of upstream migration barriers from northern California to Prince William Sound, Alaska (Figure 3.1, Table 3.1). Samples from a location were typically collected over a period of 1 d, and several sites were sampled in more than one year. Sample. sizes ranged from 13 to 62 fish per site. Fish were collected by minnow traps, angling, and downstream migrant traps. Attempts were made to collect several age classes of fish by sampling different size classes at each sample location. Two samples from hatcheries, Humboldt State University Hatchery, California, and Fall Creek Hatchery (Alsea River), Oregon, were also included in the analysis (Table 3.1). After capture, fish were euthanized (tricane methanesulfonate), weighed (g), measured (fork length FL), and photographed (left side, Ektachrome ASA 200). Each fish was tagged with an identification number that was secured to the lower jaw. Sampled fish were either frozen whole on dry ice in the field or, in the case of larger fish (>250 mm), tissue samples for allozyme analysis were dissected in the field and placed on dry ice prior to transport. Liver, heart, eye, and skeletal muscle samples were collected from each fish for allozyme analysis. Muscle samples were taken from right DD Figure 3.1.

Tissue samples from each fish were placed in tubes labeled with the fish identification number. Tissues from fish that had been frozen whole in the field were dissected in the laboratory. Coastal cutthroat trout and steelhead (0. mykiss) cooccur in many parts of their ranges (Scott and Crossman 1973; Behnke 1992), are phenotypically very similar, and share many alleles (Campton and Utter 1985). To avoid inadvertently including steelhead4 in the genetic analysis, I developed an a priori decision rule to identify steelhead individuals and remove them from the analysis based on two classical taxonomic traits. Basibranchial teeth are absent in coastal 0. mykiss and the maxillary extension extends beyond posterior portion of eye in 0. o. clarki (Scott and Crossman 1973; Scott and Crossman 1973; Behnke 1992; Moyle 2002). In addition, the presence of a yellow, orange, or red line in the skin folds of the lower jaw often occurs and gives "cutthroat" their name. Individuals with a maxillary extension score of 0 or 1 (maxillary did not extend past the posterior portion of the eye) and an absence of basibranchial teeth were designated as a steelhead and not included in the analysis. An individual with a maxillary extension score of 2 or the presence of basibranchial teeth was designated as a coastal cutthroat trout. Allozyme analysis followed methods of Aebersold et al. (1987). Thirteen enzymes encoded by 30 loci were screened (Table 3.2). A known standard from rainbow trout (0. mykiss) was placed on each gel as a reference for electrophoretic mobility for aid in identifying alleles. For purposes of this study, all 0. mykiss collected will be referred to as steelhead since all samples were obtained downstream of migration barriers, although some nonanadromous 0. mykiss (rainbow trout) may be included.

Data analysis The number of polymorphic loci, percentage of polymorphic loci, mean number of alleles per loci, and expected proportion of heterozygotes (He) were calculated for each sample as measures of genetic variation within samples. Polymorphic loci were those loci which at least one sample had a frequency of the most common allele less than or equal to 0.95 (P095). The expected proportion of heterozygotes (i.e., average heterozygosity) was calculated for each locus and averaged over all loci (Weir 1996). Genotypic frequencies were examined for consistency with Hardy-Weinberg expectations with exact probability tests, using BIOSYS-il (Swofford and Selander 1997) and Genetic Data Analysis (GDA) (Lewis and Zaykin 2002). Measures of within population genetic variation did not include duplicated loci (sIDHp1,2*; sMDHA1,2*; sMDHB1,2*) since expected values could not be calculated for a pair of loci. A sequential Bonferroni correction (Rice 1989) was used over the multiple tests carried out(k= 864). Population differentiation was examined by testing for homogeneity of allele frequencies among all samples and between all pairs of samples with exact probability tests using a Markov chain method by GENEPOP 3.3 (Raymond and Rousset 1995). The combination of probabilities at all loci, a global significance over all loci, was obtained using Fisher's method for test combination (Sokal and Rohlf 1981). Estimates of subpopulation structure were obtained using Wright's F-statistics (Wright 1978) calculated by Weir and Cockerham's 0 (Weir and Cockerham 1984), to correct for sample size and number of populations allowing comparisons with different types of molecular markers (Excoffier et al. 1992). A 95% confidence interval of U over all loci was estimated by bootstrapping (1,000 replications) over loci. Hierarchical gene diversity analysis was performed using HIERARCHY and WRIGHT78 in BIOSYS-il 72 (Swofford and Selander 1997) with population assigned to one of four regional areas (see below). Genetic distances between populations were estimated with Cavallis-Sforza and Edwards chord distance, DCE (Cavalli-Sforza and Edwards 1967). Dendrograms based on both neighbor-joining (Saitou and Nei 1987) and the unweighted pair-group method with arithmetic averages (UPGMA) algorithm (Sneath and Sokal 1973) were constructed using DCE. The robustness of the branches were evaluated by bootstrapping the distance matrix (1,000 replications) and finding the consensus tree using the programs NEIGHBOR and CONSENSE in PHYLIP 3.57c (Felseristein 1995). Steelhead from Suntaheen Creek, Alaska, were included as an outgroup in the dendrograms. Non-metric multidimensional scaling analysis (MDS) (Kruskal 1964a; Kruskal 1964b) was used to create a plot of the locations in three dimensions based on allele frequencies of 12 polymorphic loci (P095). The Suntaheen Creek steelhead sample along with a sample of 0. mykiss from Bakeoven Creek, tributary to the Deschutes River, Oregon (Currens 1997), were used as outgroups for the MDS analysis. The reduced set of loci (GPI-A1 GPI-B1 GPIB2*, rnIDHp2*, sIDHp- 1,2*, LDHB2*, sMDHA1,A2*, sMDHB1,B2*, sMEP1*, sMEP2*, PEPA*, PGDH*) corresponded to data from Currens (1997). Mantel tests (Mantel 1967) were used to test for isolation by distance (IBD) by comparing distance matrices describing geographic and genetic relationships among sampling locations (Oden and Sokal 1986; Slatkin 1993). Pairwise O(i.e., pairwise FST) values were calculated for all comparisons and were plotted against the pairwise geographic distance (km). A product-moment correlation, r, and the Mantel test statistic, Z, were computed to measure the degree of relationship between the two matrices using NTSYS (Rohlf 2000). The significance of the correlations were tested by randomly permuting (10,000 permutations) rows and columns of one of the 73 matrices while keeping the other constant resulting in the sampling distribution of the test statistic under the null hypothesis that there is no correlation (Smouse et al. 1986). Geographic distances were calculated using a geographical information system (GIS) AML method developed by Bunn et al. (2000) that used least-cost modeling to determine distances between sampling locations. Distances were calculated two ways. One approach calculated the shortest water distance between each pair of locations. The second approach calculated the shortest water distance with a water depth constraint (i.e., crossing shallow water was less costly than crossing open, deep water). Avoidance of deep water areas in the marine environment by coastal cutthroat trout has been suggested (Jones and Seifert 1997). Paths between sampling locations was restricted to depths less than 1500 m. Ocean depths less than 1500 m were partitioned into four depth classes: < 100 m, 100 - 500 m, 500 - 1000 m, 1000 1500 m. Spatial distribution of genetic variation was characterized with spatial autocorrelation analysis. A nonlinear multivariate Mantel correlogram (S. Goslee, USDA-ARS Pasture Systems and Watershed Management Research Unit, University Park, PA; personal communication, 2003) was used to examine the relationships between genetic variation and spatial structure. The Mantel test assumes a linear correlation between the two distance matrices and is based on the general hypothesis that samples close in space are similar genetically. Because the Mantel test averages the correlation over all distance classes, a Mantel correlogram was used to examine the spatial scale of the correlation. A Mantel correlogram assesses the Mantel correlation between genetic distance and geographic distance in specific distance classes and provides a picture of how the correlation changes over the spatial extent of these data (Oden and Sokal 1986). The distance classes were selected so as to be of equal widths following Sturge's rule (Legendre and Legendre 1998). 74 To determine if there were regional differences in genetic population structure and IBD, sampling locations were partitioned into four regional groups (Table 3.1; Figure 3.1). The regional groups were based on general biogeographical boundaries largely driven by Pleistocene glaciation. Region A represents the northern portion of the current coastal cutthroat trout distribution and although subjected to glacial cover during the Pleistocene, some refugia are considered to have existed in areas of the Queen Charlotte Islands, west coast Prince of Wales Island, and north of the current coastal cutthroat trout distribution (McPhail and Lindsey 1986). This region includes the Skeena, Nass, and Stikine river systems. Region B represents the Puget Sound and southern British Columbia coast that was completly covered by glaciers and includes the Strait of Juan De Fuca, Strait of Georgia, and the Fraser River system (McPhail and Lindsey 1986). Region C represented coastal locations that experienced some glacial coverage in the northern portion, but even in the northern portion rufugia may have existed (e.g., northern Vancouver Island). This region includes the Columbia, Chehalis, and Umpqua river systems. Region D was partitioned out from region C based on the slight genetic affinity detected and the stronger meristic affinity (Chapter 2) exhibited by samples south of Cape Blanco. This region includes the Rogue and Kiamath systems. 3.4. RESULTS Of the 1,619 fish initially collected, 98 steelhead were identified based on the absence of basibranchical teeth and a short maxillary extension and were excluded from the genetic analysis. Fish that only met one of the two criteria (i.e., absence of basibranchical teeth or a short maxillary extension) were not excluded from the analysis. One sample contained only steelhead (Suntaheen Creek, Alaska, location number 4) and was only used as an outgroup. Subsequent analyses were based on data from a total of 1,413 coastal cutthroat trout from 54 locations (Table 3.1) with 95 alleles segregating at 30 loci. Seventeen of these loci had an average frequency of the most common allele of 0.95 or less in at least one sample: CKB*, GAPDH2*, GDA]*, GDA2*, GPIA1*, GPIB1*, GPIB2*, mIDHp2*, sIDHp1,2*, LDHB2*, sMDHAl,A2*, sMDHB],B2*, sMEP1*, sMEP2*, PEP-A *, PGDH*, 5SOD* (Appendix Al 1). Nine loci were monomorphic in all samples (FBALD2*, G3PDH2*, GAPDH3*, GAPDH4*, GAPDH5*, LDHA1*, LDHA2*, LDH-B1 *, and mIDHp-1 *) and 11 private alleles were detected (Table 3.3). Of particular note, the frequency of the private allele sMEP-2 * 90 was 0.13 in the sample from Martin River, Alaska. Average heterozygosity (He) ranged from 0.036 (Siletz River, OR 43) to 0.101 (Widow White Creek, CA 54) with a mean of 0.062. The percentage of polymorphic loci (P095) ranged from 7.4% to 25.9% with a mean of 17.4% (Appendix Table A3. 1). The mean number of alleles loci ranged from 1.1 to 1.4 (Appendix Table A3. 1). No latitudinal dines or regional patterns were detected in any of the measures of within population genetic diversity (Appendix Figure A3.1). Samples generally conformed to Hardy-Weinberg expectations. Only 20 (2.3%) of the 864 locus/sample combinations were significant after application of the sequential Bonferroni correction for multiple comparisons (Appendix Table A3.2). Three loci (GDA-1 GDA2*, and GPI-B/ *) contributed disproportionately to the number of test not conforming to HardyWeinberg expectations. Seventeen of the 20 significant tests after sequential Bonferroni correction were a result of a deficiency of heterozygotes at one of these three loci. At the scale sampled, coastal cutthroat trout from different locations across their distributional range were composed of genetically distinct populaitons. Genetic differentiation among the 54 samples was significant (P < 0.05) for 16 of the 17 Table 3.3. Location and frequency of private alleles detected from 54 samples of coastal cutthroat trout.

Significant heterogeneity in allele frequencies found in all pairwise comparisons indicates that coastal cutthroat trout sampled in different locations across their distributional range were composed of genetically distinct populations. The global multilocus estimate for Owas 0.13 1 ± 0.045 (Table 3.4). The 95% confidence interval based on bootstrapping (0.176 - 0.086) was greater than zero indicating a heterogenous distribution of the genetic variability of coastal cutthroat trout over its distributional range. Regional estimates of 0 ranged from 0.084 (Washington and Oregon coast, region C) to 0.101 (Puget SoundlStrait of Juan De Fuca/Strait of Georgia area, region B) (Table 3.4). There were no significant differences in 0 among regions (i.e., the 95% confidence interval of Ofor each region based on bootstrapping overlapped the 0 estimate for each region). These regional 95% confidence intervals were all greater than zero indicating a heterogenous distribution of genetic variability within all regional groups. Hierarchical gene diversity analysis found that allele frequency differences among populations was 10.9% with differences among populations within a regional area contributing more to the variation than differences among regions (Table 3.5). Genetic similarity of coastal cutthroat trout populations from, locations in geographic proximity was most evident at large spatial scales, although some finer scale genetic affinity corresponding to geographic proximity was observed. The unrooted neighbor joining tree developed from DCE distances illustrates a slight geographic affinity of coastal cutthroat trout populations at a regional scale and a distinct separation of the 0. mykiss sample from the 54 coastal cutthroat trout samples (Figure 3.2). Although there was weak bootstrap support for the neighbor joining tree with only 19 of the branches having bootstrap support of greater than 30%, the geographic affinity illustrated by the consensus tree should not be dismissed given the Table 3.4. Regional and overall F-statistics and correlation results from Mantel test for isolation-by-distance based on 0(17 polymorphic loci) and geographic distance (shortest water distance). The upper and lower bounds of the 95% confidence interval for F-statistics were derived from bootstrapping over loci (1,000 replications).

Neighbor-joining bootstrap percentages based on 1,000 replications, only percentages greater than 30% shown (e.g., 73), scale bar represents bootstrap values, not genetic distance. Location numbers correspond to Table 3.1 and Figure 3.1. number of populations in the analysis and the number of possible trees (1,000 replications). All but one of the Alaska samples are located in the "lower portion" of the consensus tree (Figure 3.2) and only three non-Alaska samples are located in this portion of the tree (locations 22 San Josef River, 30 Hoko River, and 33 Hoh River). These sites are three of the five most northern sites in regional group C, perhaps explaining their apparent affinity with the more northern Alaskan sites. The general tree topology observed would not be inconsistent with a radiation from a common ancestor. The long branch lengths suggest a distinctiveness of each population and are consistent with the significant heterogeneity in allele frequencies found in all pairwise comparisons. This adds further support that the coastal cutthroat trout populations from different locations across their distributional range were composed of genetically distinct populations. The steelhead sample (Suntaheen Creek, Alaska) appears to be quite different based on the neighbor joining tree. The UPGMA rooted dendrogram based on DcE distances also illustrates some geographic affinity of coastal cutthroat trout populations at a regional scale and a distinct separation of the 0. mykiss sample (Figure 3.3). Five of the eight samples from southern Oregon/northern California (regional group D) grouped together, separately from all other samples; included with these southern samples was the sample from the Martin River, Alaska (location 2), near the northern extent of the distributional range of 0. o. clarki. Although there was weak bootstrap support for the UPGMA dendrogram with only 17 branches having greater than 30% support, some geographic concordance was illustrated by the consensus dendrogram (Figure 3.3). There was 100% bootstrap support for separation of the 0. mykiss sample from the 54 coastal cutthroat trout samples. Similar to the consensus neighbor joining tree, a large portion (12 of 17) of the region A samples showed geographic affinity and grouped outside of [3' 40 20 38 A 31 29 27 20U 34 39A 12 0 30 30 A 33 A 21 D 36 17 0 26A 51 35 A 60 70 50 22 A 37 A hi 24 47 A 53 8 25 44A 10 0 42 A 23 54 . 28i 55 . 52 50 45 40 43 41 46 32 G A A A A A A 130 160 14 0 11 0 80 10 150 48 49 19 0 90 180 Figure 3.3.

Bootstrap percentages based on 1,000 replications, only percentages greater than 30% shown (e.g.. 73). Location numbers correspond to Table 3.1 and Figure 3.1. the major cluster that included samples from all regions. The sample from Martin River, Alaska (location 2), appears to be even more distinct in the consensus dendrogram (Figure 3.3). As with the neighbor joining tree, the relatively long branch lengths in the dendro grams agree with the heterogenous allele frequency distributions and suggest significant levels of differentiation among the samples collected. The slight geographic concordance evident in the cluster analysis becomes more, evident in the multidimensional scaling (Figure 3.4). The stress value of 0.111 of the MDS analysis is considered good, a value of 0.05 would he considered excellent, 0.0 perfect, and 0.2 poor (Kruskal 1964a). In the multidimensional space illustrated in Figure 3.4, samples from region A make up all of the samples in the lower left portion of the plot (low axis I and axis H values) while only samples from region D are located in the right hand portion of the plot (high axis I values and moderate to high axis II values). Geographic affinity is also apparent at smaller spatial scales such as along the northern Washington coast and Srait of Juan De Fuca where several adjacent sampling locations grouped together in MDS space (Hoko River location 30, Salt Creek - location 31, Quillayute River location 32, and Hoh River location 33). As in the cluster analysis, the steelhead sample (Suntaheen Creek, Alaska) appears to be quite different than all the coastal cutthroat trout samples when represented by MDS (Figure 3.5). This difference does not appear to be unique to the Suntaheen Creek sample, an 0. mykiss sample from Bakeoven Creek (Deschutes River, Oregon) from Currens (1997) shows phenetic affinity for the Suntaheen Creek sample and both are quite different from all the coastal cutthroat trout samples (Figure 3.5). Across their distributional range, coastal cutthroat trout show a pattern of strong isolation by distance with samples from geographically adjacent locations being more similar than they are to populations from locations further away.

Location numbers correspond to numbers in Table 3.1. B akeoven Creek data from Currens (1997). distance exhibit highly significant associations with genetic distance (pairwise F) and geographic distance. Significant associations were detected using both the shortest water distance (Figure 3.6; Mantel r = 0.415, P = 0.0001) and depth constrained water distance (Figure 3.7; Mantel r = 0.395, P = 0.0001). The association of genetic distance and geographic distance varied among regions (Figures 3.8 and 3.9) with significant (P 0.10) associations being observed in region A (Mantel r = 0.23 8, P = 0.079) and region D (Mantel r 0.436, P = 0.099). This is in contrast to genetic variation that was similar among the regions (Table 3.4). Based on plots of pairwise FST and geographic distance (Figure 3.8 and 3.9), it is evident that the range in pairwise distances are different among the regional groups, specially region D where no pairwise distances greater than 229 km. Isolation by distance appears to be significant at shorter distances regardless of the regional area across the distributional range of coastal cutthroat trout. The Mantel correlogram indicates that the association of genetic distance and geographic distance (shortest water distance) is strongly positive and significant (P 0.05) at short distances. In other words, fish from a location are more similar genetically to fish from nearby locations than they are to fish from distant locations. The correlation becomes not significantly positive at approximately 740 km (Figure 3.10 and Table 3.6). Significant negative associations begin to occur at distances greater that 1,243 km. That is, at distances greater than 1,243 km the genetic differences (i.e., statistically significant differences) between fish from two sites increased with distance. For Figure 3.10, distances classes greater than distance class 19 (2,137 km) should be ignored since they are based a small number of pairs and therefore have low statistical power (Legendre and Legendre 1998) (see also Table 3.6). Regional Mantel correlograms were not generated because of the low number of pairs in all distance classes. r.1sI 0.35 S Mantelr=0.415 S S 0.30 S 0 .5S . . 0.25 P-value = 0.0001 . S ..

The use of depth constrained water distance provided similar results (Figure 3.11 and Table 3.7). The correlation becomes not significantly positive at distances of approximately 825 km. 3.5. DISCUSSION Across the distributional range of coastal cutthroat trout, genetic population structure was primarily at the individual stream level (i.e., sampling location in this study). This survey was based on samples collected over a five year period, providing a snap shot of genetic variation and the distribution of this variation that existed from 1992 to 1996. Significant genetic variation was found among 54 sample sites consisting of 1,413 individual coastal cutthroat trout from across their distributional range. In the only survey to date that has examined populations across their distributional range, I found regional differences in how genetic variation was distributed across the landscape even though the amount of genetic variation within regions was similar. Geographic concordance of populations at the northern and southern extent of the subspecies range was observed and isolation by distance was evident at regional scales (<800 km). My results based on samples collected across the range of the subspecies were consistent with the hypothesis that coastal cutthroat trout from each sampling location were from genetically distinct, isolated populations. When examining intra-regional patterns of genetic population structure, my results were not inconsistent with those reported by others using allozymes (Campton and Utter 1987) and microsatellites 93 -S \. 0.5 S S 0 0 0.0 0 0 \ /°\ 0 / . -, -0.5 /\ \ \/ S S \ -1.0 \/\ \ S 0 500 1000 1500 2000 2500 3000 Distance (km) Figure 3.11.

Wenburg and Bentzen (2001) found significant heterogeneity among all populations and pairs of populations in tests of genotypic differentiation from coastal cutthroat trout collections from the Hood Canal, Washington. The amount of variation observed within each regional area was significantly different than zero and did not differ among regions. Genetic diversity as measured by various measures of genetic diversity (e.g., heterozygosity, number of polymorphic alleles) was similar across the range of coastal cutthroat trout. The contribution to the total gene diversity was greater among populations within regions (8.6%) than among regions (2.5%), while 88.9% of the total gene diversity was within populations. Campton and Utter (1987) found allele frequency differences between the north Puget Sound and Hood Canal regions contributed the most to the total genetic variation among the coastal cutthroat trout populations they examined while differences among basins within a region only contributed a small proportion to the total genetic variation observed. The contrast of my results to those of Campton and Utter (1987) are a result of the regional groupings made in both studies. All of the populations sampled by Campton and Utter (1987) and placed into two regions would have been included in a single geographical region in my study. Similarly, Beacham et al. (2003) delineated samples within the Fraser River drainage into six regions and found that the genetic population structure of Fraser drainage Chinook salmon had a strong geographic basis with regional differences accounting for approximately twice the variation in allele frequency as within regional variation among populations. Beacham et al. (2003) sampled at a finer spatial scale than I did and the geographic extend of their six regions would be represented by a single, larger regional group at that spatial scale used in my analysis. Reisenbich1r et al. (1992) found regional differences between northern and southern populations of steelhead sampled between the Columbia River and Mad River, California, but not within basin or intra-regional genetic differentiation (10 allozyme loci). The spatial extend of the regional scale used by Campton and Utter (1987), Beacham et al. (2003), Reisenbichier et al. (1992) and in other studies are smaller than the regional spatial scale used in my study and this helps explain the relatively large contribution of among population gene diversity within a region that I observed versus the low within region but high among region gene diversity reported in other studies. Compared to other species of anadromous salmonids, the amount of genetic diversity attributed to differences among populations was high in coastal cutthroat trout (Table 3.8). This is consistent with other studies that have been conducted at smaller spatial scales and suggest a range-wide consistency in the population structure of coastal cutthroat trout. Slight geographic concordance was observed in both the neighbor-joining and UPGMA clustering approaches for samples located at the northern and southern extend of the range. Although bootstrap support was weak, my results suggest slight regional grouping of coastal cutthroat trout throughout their range, particularly at the northern and southern extend of their range. Campton (1987) found anadromous coastal cutthroat trout in the Puget Sound were primarily structured at the between-region (North Puget Sound versus Hood Canal) and among-stream levels (streams within a drainage). Wenburg and Bentzen (2001) proposed that the strongest contributor to population structure of anadromous coastal cutthroat trout was differentiation at the level of individual creeks in their survey that included 22 sites from the Hood Canal, Puget Sound, and several coastal Washington sites. The analysis of isolation by distance based on the Mantel correlograms indicated that at regional scales (i.e., distances <800 km) populations of coastal cutthroat trout exhibited a strong pattern of isolation by distance. The strength of IBD differed among Table 3.8. A summary of genetic diversity analyses of selected salmonid species.

Wenberg and Bentzen (2001) found genetic distances between populations of coastal cutthroat trout in the Hood Canal, Washington, were positively correlated with geographic distance at spatial scales smaller than that of this study; but partial reproductive isolation was still evident with significant differences in genotype frequencies found between sampling locations separated by as little as 2 km. At a spatial scale larger than the Hood Canal, Wenburg et al. (1998) found significant correlation between genetic distance and geographic distance among 13 coastal cutthroat trout populations throughout Washington using DCE but not when using °ST and PST Stronger IBD at smaller spatial scales is also suggested by Wenburg and Bentzen (2001) that found two of three genetic distance measures significantly correlated with geographic distance within the Hood Canal but only one of three genetic measures significantly correlated when samples included sites throughout Washington. Others have found similar patterns of population structure in salmonids. Recently Olsen et al. <1898 Id> found patterns of coho salmon genetic population structure similar to patterns found in my study of coastal cutthroat trout. Olsen et al. (2003) reported significant intra-regional population differentiation, large among population differentiation (FST= 0.099), phenetic clustering only exhibited weak geographic concordance, and IBD was strong at small spatial scales. Fontaine et al. (1997) found that the relative positions of Atlantic salmon populations in a neighbor-joining phenogram did not correspond with their geographical proximity. They found an intraregional correspondence between genetic distance and geographic location that broke down when interregional populations where included in their analysis (Fontaine et al. 1997). Estoup et al. (1998) found poor congruence between dendrogram topology and geographic distance from 11 nonanadromous brown trout populations separated by 2.5 to 850 km (Vosges massif, France). Although samples from adjacent locations were significantly different indicating limited gene flow (Estoup et al. 1998), strong IBD and a significant tendency for errors in assignment tests to assign individuals to one of the nearest populations indicated a high level of microgeographic structuring of these brown trout populations. Castric et al. (2001) found their population phenogram illustrated an overall lack of population grouping by drainage or any other hierarchical clustering among 30 populations of brook charr in six major river drainages in Maine. In addition, Castric et al. (2001) found reversed IBD (i.e, greater genetic similarity with increased geographic distance). Costello et al. (2003) found significant IBD among populations of bull trout in British Columbia and Alberta, Canada, but weak bootstrap support for a neighbor-joining tree that tended to group populations by physiogeographic region. Patterns of genetic population structure found in this study along the Pacific coast from Vancouver Island, British Columbia, to Cape Blanco, Oregon (regional area C in this study) and non-coastal basins in Puget Sound, Strait of Juan de Fuca, and Strait of Georgia (regional area B in this study) may be a result of Pleistocene glaciation or an artifact of the many years of hatchery releases; including the introduction of hybrids, that has occurred in this region (Johnson et al. 1999). These two regional areas (A and B) had the weakest IBD yet still had significant genetic variation (0> 0). Cutthroat trout and steelhead hybrids ("cutthroat cross trout") were released as early as 1912 by the State of Washington in the Nisqually River, Puget Sound, Washington (Riseland 1912). Hatchery coastal cutthroat trout were introduced in British Columbia streams as early as 1930 (Hartman and Gill 1968), although Hartman and Gill reported that introductions were into areas already occupied by coastal cutthroat trout, were generally not successful, and were unlikely to have influenced distribution of coastal cutthroat trout in their survey area. In addition to the release of hybrids, out of basin transfers have occurred. As a result of poor returns from an anadromous coastal IDI cutthroat trout program in Washington in the 1950s, hatchery coastal cutthroat trout from the Alsea River in Oregon were brought in followed by crosses with steelhead in the late 1 960s (Crawford 1979); these efforts to establish high return rates of hatchery coastal cutthroat trout were not successful (Crawford 1979). Recent hatchery production of anadromous coastal cutthroat trout has been focused on providing sport fishing opportunities and has occurred primarily in Puget Sound, Grays Harbor, the Lower Columbia River, and the Oregon coast (Johnson et al. 1999), although since 1997 no releases of hatchery coastal cutthroat trout have occurred in Oregon coastal streams that contain anadromous coastal cutthroat trout (Hooton 1997). Recent genetic surveys of Washington coastal cutthroat hatcheries found hybrids in the Aberdeen Fish Hatchery and the Beaver Creek Fish Hatchery, Colombia River (Johnson et al. 1999). The meristic rule used to identify 0. mykiss individuals resulted in very distinct separation of steelhead from coastal cutthroat trout in the clustering and ordination procedures. Other molecular markers have been developed (Wenburg et al. 1998; Ostberg and Rodriguez 2002) that would provide greater resolution for species identification than the allozymes used in this study and may provide additional insight into 0. o. clarki and 0. mykiss hybrid issues in future analyses of my samples, especially in studies designed specifically to examine hybridization. Determining genetic structure can be complicated by hybridization. The possibility of hybridization with steelhead exists for many populations of coastal cutthroat trout. Wilson et al. (1985) used mtDNA sequencing to analyze populations of steelhead and rainbow trout (anadromous and resident forms, respectively) and a population of coastal cutthroat trout. With few exceptions, their results indicated detectable divergence among all geographic populations of steelhead and rainbow trout. hiterspecific nucleotide divergence between 0. mykiss and 0. c. clarki was two- to four-fold larger than intraspecific divergence detected within 0. mykiss. Based on a 101 base substitution rate of 2% per million years (estimate based on mutation rate calibration determined from primates therefore, used with caution), Wilson el al. (1985) estimated that 0. mykiss 0. clarki clarki divergence occurred 1 to 2 million years ago. Behnke (1992) speculated that in small streams where two species of trout are found, crossbreeding occurs if reproductive isolation (e.g., limited niche diversity, insufficient space to allow physical separation at spawning) breaks down. Campton and Utter (1985) used allozymes to identify juvenile fish with intermediate phenotypes consistent with those expected for decedents of coastal cutthroat trout and steelhead and was the first formal documented observation of hybrids in the wild, and led the authors to suggest that in streams where both species spawn "the production of hybrid offspring may not be uncommon". More recently, many genetic studies have detected the occurrence of hybrids between coastal cutthroat trout and steelhead in the wild (Hawkins 1997; Wenburg et al. 1998; Young et al. 2001). Surprisingly, no samples appeared to be intermediate to 0. mykiss and 0. clarki in multidimensional space (Figure 3.5). The MDS ordination analysis of my samples that included two outgroups of 0. mykiss did not exhibit any populations intermediate to the two species. Based on reports in the literature that concluded that hybridization between coastal cutthroat trout and 0. mykiss to be widespread throughout the range of coastal cutthroat trout populations on the West Coast (Johnson et al. 1999), one might expect some of my samples to include hybrids that would be intermediate to steelhead and coastal cutthroat trout in the multidimensional space. This lack of intermediate populations may be due to differences in the loci and number of loci used in the different studies, my application of an independent morphological rule (short maxillary extension and absence of basibranchial teeth) to exclude misidentified 0. mykiss from the analyses, and the inclusion of older fish (fish >1+) in many of my samples. Johnson et al. (1999) did observe hybrid individuals most often among age 0+ and 1+ 102 fish and seldom in adults. In addition, Johnson et al. (1999) used a larger set of loci and used three fixed or nearly fixed loci (ADA-2 mAH-2 *, and CK4-2 *) to identify and exclude 0. mykiss individuals that had been inadvertently included in their samples and used a decision rule based on eight loci (sAAT4*, ADA2*, mAH2*, mAH-3 <, CKA 2*, IDDH-1 sIDH2*, and sMEP2 *) to attempt to identify and exclude suspected hybrid individuals from their analyses. Consistent with my results that did not exclude any suspected hybrids, Johnson et al. (1999) reported that coastal cutthroat trout samples in their analysis were closely clustered together and were well differentiated from steelhead after excluding suspected hybrids based on the presence of steelhead like alleles. In addition, surveys such as mine were not designed to estimate hybridization and should be viewed with caution when inferring range-wide hybridization patterns. In my study, no individuals other than 0. mykiss (based on, the absence of basibranchical teeth and a short maxillary extension) were removed from the analysis. I did not use or have results across all samples for many of the loci used by Johnston et al. (1999) to identify hybrids. The reduced loci set I used may have limited my ability to detect the extent of hybridization observed by others. My samples were collected by a limited number of people, perhaps providing a bias against collecting hybrids. Recently Baumsteiger (2002) found that expert evaluators were almost always able to successfully identify coastal cutthroat trout in the field, but had moderate difficulty identifying steelhead and were not able to correctly identify hybrids. In addition, the morphological rule I used to identify 0. mykiss may have eliminated hybrids from the analysis resulting in the lack of intermediate populations in the MDS analysis. I did not perform analyses on individuals, rather allele frequencies of populations were used perhaps masking the presence of hybrid individuals. 103 Recently, studies to examine hybridization between coastal cutthroat trout and steelhead found that the occurrence of hybrid coastal cutthroat trout and steelhead was not randomly distributed among populations they sampled in the Puget Sound and Washington coast region (Young et al. 2001). Campton and Utter (1985) concluded that a post zygotic isolating mechanism may be contributing to the preservation of species integrity given the infrequent observation of adult hybrids. Behnke (1992) speculated that although gene flow may occur between coastal cutthroat trout and coastal rainbow trout (i.e., steelhead), reproductive isolation typically does not break down completely and it is uncommon to find a hybrid swarm typically found when interior cutthroat trout species hybridize. Hawkins and Foote (1998) did not find reduced viability of hybrids between coastal cutthroat trout and steelhead in hatchery experiments, but did report a mismatch between egg size and development rate relative to pure species that may "play an important role in limiting introgression between the species." These data suggest that compared to other species of Pacific salmon and trout, coastal cutthroat trout are characterized by many smaller, genetically more diverse local populations that act in a more independent, isolated nature over short time frames (<100 years). For example, on average approximately 11% of all genetic differences we observed (total gene diversity) was attributed to differences among populations (0 = 0.131). This was much greater than that reported for other species of anadromous salmonids in western North America. Consistent differences occurred among populations from different regions (Alaska, Washington/Oregon, and California), but within regions there was less geographical structure than that observed among populations of other Pacific salmon and trout. Genetically, this can be explained by genetic drift (common in small populations), by founder effect (common in small 104 populations in areas with dynamic habitat conditions or where species are colonizing new habitat), and by periods of low dispersal. I believe that differences in genetic population structure between coastal cutthroat trout and other Pacific salmon and trout may reflect life-history differences among species. The many migratory life-histories that coastal cutthroat trout have evolved, for example, would be advantageous in unpredictable habitats where small populations expand, decline, or become extinct with changing conditions. Dispersal, which would be more likely with fish that migrate, might be rare or consist of only few individuals, but they may be crucial for reestablishing populations in adjacent habitat following localized extinctions or as new habitat becomes available. Understanding genetic population structure across the landscape is critical to developing appropriate conservation and management plans, but it will not paint a complete picture of what is needed for development of appropriate conservation plans. Knowledge of life history differences adds to this picture, but to bring it all into focus one needs to also understand the habitat dynamics that coastal cutthroat trout have adapted to and will be faced within the future. Connectivity of biological and physical processes throughout the basin must be considered for management, conservation, and restoration efforts (Reeves et aL 1995). The slight geographic concordance of populations at the northern and southern extend of the range and the regional separation of the southern populations suggest coastal cutthroat trout populations at the periphery of the range have faced different habitat conditions (both marine and/or freshwater) than populations located in the central part of the distribution. Studies of other organisms have found that in general, peripheral populations tend to be genetically and morphologically divergent from central populations (Lesica and Allendorf 1995). Lesica and Allendorf (1995) reviewed various aspects of peripheral populations and their value to species 105 conservation with special attention to the distinction between marginal versus peripheral habitat conditions. The southern populations occupy habitat that ecologically marginal in addition to being at the geographic margins of the distributional range. Southern populations have experienced different habitat conditions (i.e., Kiamath Province, etc.) than adjacent populations along the Oregon coast and throughout the range of coastal cutthroat trout whereas the northern populations occupy areas that are similar to conditions throughout a large part of the distributional range. Coastal basins in Oregon south of, and including the Sixes River, drain the Klamath Mountains and the unique geology that makes up the Klamath Mountains Geologic Province (McKee 1972). Sampling locations from the region include locations 48 to 55. Conservation units for coastal cutthroat trout need to reflect appropriate geographic areas based on the distribution of genetic diversity and life history variation among populations. For instance, because small populations are typically at greater risk of extinction than larger populations and because of the high gene diversity found in coastal cutthroat trout, conservation measures designed for other Pacific salmon and trout populations with larger, more connected populations may not be appropriate for coastal cutthroat trout. The recent findings of Channell and Lomolino (2000) that found as a species becomes endangered they tend to persist in the periphery of their historical geographical range places a greater emphasis on these peripheral populations of coastal cutthroat trout when conservation plans are developed. Although there is no indication that there has been a contraction of the distribution of coastal cutthroat trout, long-term conservation plans are likely to depend on protection of distinct populations (Lesica and Allendorf 1995), particularly peripheral populations in marginal habitats that may contain high adaptive significance to the species as a whole (Scudder 1989). The connections and interactions among local populations that are important for both 106 regional and local persistence are likely to be disrupted by management. Risks of local extinction, both deterministic and stochastic, may be partially addressed through management actions at the stream or watershed scale; long-term persistence will require consideration at a much larger scale. 107 4. CONCLUSION The results of my genetic and meristic survey of coastal cutthroat trout populations across their distributional range found many diverse local populations with interregional differences in the distribution of that diversity across the landscape. These data suggest that compared to other species of Pacific salmon and trout, coastal cutthroat trout are characterized by more diverse local populations that act in a more independent, isolated nature. The amount of sub-population genetic structure in my study did not differ among regions, but the strength of isolation by distance differed among regions with the strongest isolation by distance being detected at the northern and southern extent of the range (Chapter 3). The northern and southern populations exhibited geographic concordance based on allozymes (Chapter 3), but only the southern populations exhibited meristic phenetic affinity at the regional spatial scale (Chapter 2). The southern populations were relatively distinct in terms of their phenetic affinity (i.e., the southern populations grouped together). In addition, the among population differences in meristic characters observed in the southern region were greater than those observed within the other three regional areas. Although both meristics characters and allele frequencies exhibited significant differences among populations, the pair-wise measures of between population distances were not concordant (Figure 4.1). Lynch (1996) found such lack of concordance not surprising for reasons related to statistical sampling and the weak relationship between molecular and quantitative-genetic variation. Additionally, it has been found that morphological and molecular evolution can occur at independent rates (Avise 1994). Salducci et al. (2004) recently found a discordance in resolution between population subdivision of the cyprinid Leuciscus souffia soufJia using aliozymes and meristic characters; they attributed the lack of concordance to insufficient differences Ip 0.05 e) 0 S 0.03 S .

The lack of concordance I observed could be a result of many different scenarios, including strong environmental influence on meristic characters or differential selection acting on the characters and loci. Another factor contributing to the lack of concordance between population structure based on meristic and allozyme characters is that the meristic measures are phenotypic traits that are very likely polygenic traits (i.e., the expression is a function of appropriate alleles at numerous loci (Avise 1994)) whereas the allozyme analyses used the frequency of various genotypes to characterize a population. The implications of this lack of concordance between these two measures of population differentiation are not restricted to these meristic or allozyme derived population studies. Conservation planning for any species requires an understanding of the interaction among populations across different geographic scales and a maintenance of historical genetic population structure. However, efforts might be better directed if they focused on maintaining adaptive diversity rather than relying on a measure that reflects genetic isolation (Crandall et al. 2000). The extant in which either my meristic or allozyme measures captures a trait that enhances the potential for coastal cutthroat to persist is unknown. Until further is known about the adaptive significance of the population differences I detected, a conservative approach to the use of these data would call for a recognition of the population subdivision suggested by both the meristic and genetic measures (i.e., southern populations distinct, geographic affinity of populations at the northern and southern portion of the range, and a primary population structure at the individual stream level). The strong geographic concordance and inter-regional divergence of meristic characters exhibited by the southern populations (Chapter 2) was consistent with other 110 ecological studies that have found peripheral populations tend to be genetically and morphologically divergent from central populations and morphological characters are expected to diverge more rapidly in isolated populations than gene frequencies (Lesica and Allendorf 1995). The persistence of a population or group of populations (e.g., metapopulation) is dependent on the presence of suitable ecosystem states and the ability of populations to track and use these patches through time. My snap-shot of population structure across the range of coastal cutthroat trout provides a glimpse of past landscape dynamics since the current population structure is a reflection of dispersal and isolation that have occurred over a range of time scales. The landscape within the distributional range of coastal cutthroat trout is dynamic in space and time ranging from the geologic processes of glaciation and volcanism that have shaped a large portion of the area (McPhail and Lindsey 1986) to other events such as fire and flood have shaped the landscape at smaller temporal (101 - 102 years) and spatial scales (watersheds and basins) (Benda 1994). These various disturbances create a shifting mosaic of abiotic and biotic conditions (Reeves et al. 1995). Across the range of coastal cutthroat trout, the pattern of temporal and spatial extent (i.e., latitudinal extent) of disturbances can be thought of as being infrequent but spatially large in the north and shifting to disturbances of a more frequent and smaller spatial scale to the south (McPhail and Lindsey 1986; Benda et al. 1998; Naiman and Bilby 1998). This is conceptually illustrated in Figure 4.2. In this simplified construct, anthropogenic disturbances represent a range of processes from land management activities to urbanization, and tectonics include processes such as coastal uplift and events such as the 1964 Alaska earthquake. The disturbance regime that coastal cutthroat trout encounter in the north is vastly different 111 North Juneau 1 .i:L"'.: ..... a p. BC/WA tL.. .1 . .. WA/OR .. OR/CA a '. . ... South Infrequent Frequent Temporal scale Figure 4.2. A simplified construct of the temporal scale (horizontal axis) and latitudinal scale (vertical axis) of disturbances in coastal basins across the distributional range of coastal cutthroat trout. 112 from that in the south. Peripheral populations of coastal cutthroat trout at the northern extent of the distribution (i.e., Alaska) occur in habitat that is marginal is terms of the distributional range, but not condition, whereas coastal cutthroat trout populations at the southern extent of the range (i.e., southern Oregon/Northern California) exist in habitat that is marginal in terms of the distributional range and condition (i.e., Kiamath Province, etc.). Coastal basins in Oregon south of, and including the Sixes River, drain the Kiamath Mountains and the unique geology that makes up the Kiamath Mountains Geologic Province. Tracking changes across the landscape in response to different environmental conditions depends on distance and habitat conditions along the route of dispersal. Coastal cutthroat trout populations at the southern extent of the range are subject to smaller, but more frequent disturbances that I believe have resulted in less exchange of individuals with populations to the north (i.e., Oregon coast) resulting in regional distinctiveness and local extinction/recolonization events resulting in higher levels of within region diversity. Variations in habitat at various spatial and temporal scales will be reflected in any snap shot of population structure. Taylor et al. (1993) used the term landscape connectivity to express the degree to which the landscape facilitates or impedes movement among areas. The opportunity for movement across the landscape during various portions of its life cycle (e.g., spawning, over-wintering, ocean migration) is critical for the survival of a local population and opportunities for individuals to move among populations (i.e., stray) are critical for recolonization following local extinctions. Movement in the marine environment can influence the observed population structure of anadromous salmonids. Avoidance of deep water areas in the marine environment by coastal cutthroat trout has been suggested (Jones and Seifert 1997) although test for isolation by distance were similar when either shortest water distance or water-depth constrained distance were used (Chapter 3). At this scale, 113 limited dispersal over deep water did not appear to be infiucencing popu'ation structure. In summary, the persistence of a population or group of populations depends the ability of populations to track changes in the environment through time and this movement of individuals across the landscape depends on the availability of suitable habitat features at various spatial and temporal scales. This suggests that understanding the historical and current spatial structuring of populations is useful for conservation and management of coastal cutthroat trout. Management and long-term conservation plans are likely to depend on protection of distinct populations (Lesica and Allendorf 1995), particularly peripheral populations in marginal habitats that may contain high adaptive significance to the species as a whole (Scudder 1989). In contrast to conventional thinking that predicts core populations persisting and range contraction as a species becomes endangered, most species (of 245 examined) persist in the periphery of their historical geographic range (Channell and Lomolino 2000). Habitat that was suboptimal historically along the periphery of a species range may provide valuable opportunities for conservation planning (Channell and Lomolino 2000), for it is in these areas one often finds divergence from central populations (Lesica and Allendorf 1995). For coastal cutthroat trout, the unique meristic characteristics of populations in the southern extent of the range suggest that these populations may be essential to conserve the range of diversity in the sub-species. But as this study has shown, assuming similar population structure across regions would be inappropriate. Rangewide conservation planning must account for differences in landscape dynamics and local population response. 114 BIBLIOGRAPHY Adams, B. K. and J. A. Hutchings. 2003.
