We summarize published and unpublished information available on the presence of macroalgae on the on tidal flats of Koenigshafen Bay (island of Sylt, North Sea), one of the more extensively studied areas of the Wadden Sea. A total of 46 green algal species, 36 brown algal species and 26 red algal species has been recorded within the last 120 years on soft and hard substrata of Koenigshafen Bay (disregarding species found unattached or drifting). Several of these species were only temporarily resident on the tidal flats. Today, at least 35 green, 15 brown and 12 red algal species occur within or close to Koenigshafen Bay. Significant long-term changes in species abundances have occurred in all three major groups of algae: Since the late 1970s, dense green algal mats dominated by Enteromorpha flexuosa, E. radiata and E. prolifera have occurred regularly on the intertidal flats, whereas a general decrease of brown and red algae has been documented. Two red algal species, Gracilaria verrucosa and its epiphyte Callithamnion corymbosum, were conspicuous members of the macro-flora until the middle of this century. Although still present in the 1980s, they have now disappeared completely. On the other hand, the brown alga Sargassum muticum has begun to colonize mussel beds. The causal background of long-term changes in the macroalgal flora of Koenigshafen Bay is discussed. Owing to substantial nomenclatural changes during the last 120 years, a revised species list with authors' names and synonyms is included. " "changes" "" "D" "Reinke, J."

It compliments the previously defined 'average taxonomic distinctness' (AvTD, Delta super(+)), which is the mean path length through the taxonomic tree connecting every pair of species in the list. VarTD is simply the variance of these pairwise path lengths and reflects the unevenness of the taxonomic tree. For example, a species list in which there are several different orders represented only by a single species, but also some genera which are very species-rich, would give a high Lambda super(+) by comparison with a list (of equivalent Delta super(+)) in which all species tended to be from different families but the same order. VarTD is shown to have the same desirable sampling properties as AvTD, primarily a lack of dependence of its mean value on the sample size (except for unrealistically small samples). Such unbiasedness is of crucial importance in making valid biodiversity comparisons between studies at different locations or times, with differing or uncontrolled degrees of sampling effort. This feature is emphatically not shared by indices related to species richness and also not by properties of the phylogeny adapted from proposals in other, conservation contexts, such as 'average phylogenetic diversity' (AvPD, Phi super(+)). As with AvTD, the VarTD statistic for any local study can be tested for 'departure from expectation', based on a master taxonomy for that region, by constructing a simulation distribution from random subsets of the master list. The idea can be extended to summarizing the joint distribution of AvTD and VarTD, so that values from real data sets are compared with a fitted simulation 'envelope' in a 2 d ( Delta super(+), Lambda super(+)) plot. The methodology is applied to 14 species lists of free-living marine nematodes, and related to a master list for UK waters. The combination of AvTD and VarTD picks out, in different ways, some degraded locations (low Delta super(+), low to normal Lambda super(+)) and the pristine island fauna of the Scillies (normal Delta super(+), high Lambda super(+)). The 2 indices are also demonstrated to be measuring effectively independent features of the taxonomic tree, at least for this faunal group (although it is shown theoretically that this will not always be the case). The combination of Delta super(+) and Lambda super(+) is therefore seen to provide a statistically robust summary of taxonomic (or phylogenetic) relatedness patterns within an assemblage, which has the potential to be applied to a wide range of historical data in the form of simple species lists."

At Sodwana Bay, we tested the hypotheses that the seaweed communities would (1) differ floristically with depth, (2) be more species-rich in shallower water, (3) show similar biomasses within the depth range sampled and (4) be affected (biomass and/or species composition) by sand. Samples were collected (using SCUBA) from reefs ('sites') at depths of about 1m, 7m, 10m, 15m and 26m. Each sample comprised all macroscopic (non-crustose) seaweeds within a 25cm x 25cm quadrat (five quadrats per depth). Environmental factors, including percentage sand cover and depth, were recorded. The seaweed communities were mainly compact turfs; a total of 82 Rhodophyta, 14 Chlorophyta and eight Phaeophyta were recorded. Ordination (canonical correspondence analysis) and classification (Twinspan) of the data showed clear differences in the floristic composition (either as species biomass or presence/absence) with depth, mainly between shallow subtidal communities (0.5-1.0m depth) and those at intermediate depths (5.5-15.0m), followed by the deepest communities (25.7-29.0m) and those at intermediate depths. The shallow samples showed the greatest species diversity. Total seaweed biomass decreased significantly with depth and percentage bare (seaweed-free) substratum increased significantly with depth, possibly because of lower wave action, light penetration, or different grazing patterns. Sand (as percentage sand cover) also affected seaweed community composition, but this showed no pattern with depth. The algal communities on these reefs at Sodwana Bay showed exceptional a-diversity, with 104 taxa (> 20% of the recorded KZN flora) occurring in the total sample area of only 1.56m(2). The seaweed communities of northern KZN are structurally and floristically similar to those of other tropical coral reefs around the world."

Particular options such as the minimum group size, the maximum split levels and both the amount and score of cut levels to be used are left to the judgement of the researcher. When using small and homogeneous data sets, the score assigned to the cut levels can be derived from intermediate transformations of the cover-abundance values, rather than transformations obtained with a strong weighting on presence, or an emphasis on dominance. Our research question is to know whether these coefficients have the same robustness for more heterogeneous and larger data sets. with a large amount of transition communities. A comparison was made between five different sets of cut levels in order to determine I he most effective one for the classification of data on a floristic gradient. The analysed cut level sets differed in the number of cut levels and in the weight provided to the cover-abundance coefficients. The classifications resulting from the different sets of cut levels were compared, by determining the amount of identical associations that were clustered together, by visualising the results of the different cut level types through DCA, by comparing the correlations between the median values of the abiotic factors in each TWINSPAN group and DCA-values of the first axis of the different cut level types. The analysis showed that the cut level types in particular derived from the original values of the Braun-Blanquet cover-abundance coefficients, reflect best the floristic gradient and the underlying structure of the data. Results on heterogeneous data sets are complementary to the previous findings in literature where better results were achieved with a combined transformation for more homogeneous data sets."

Sampling was carried out at six sites (4 to 10 quadrats per site) around the Cape Peninsula. For each of the quadrats, biomass of each species, grazing, and environmental variables such as temperature, wave exposure and sand cover were determined. The data were analysed using canonical correspondence analysis (CCA) and two way indicator species analysis (TWINSPAN). A total of 142 seaweed taxa were found at the six sites (21 Chlorophyta, 14 Phaeophyta and 107 Rhodophyta). The two sides of the Peninsula have a very different biomass-composition of Chlorophyta, Phaeophyta and Rhodophyta. The biomass of Rhodophyta in the Atlantic sites is much higher than in the Bay, and the biomass of Chlorophyta is higher in False Bay than on the west coast. A change in floristic composition of subtidal algal communities around the Cape Peninsula can be observed and is principally related to seawater temperature and wave exposure. Next to these physical factors, grazing is demonstrated to be important in determining species composition. A lower degree of wave exposure might result in a higher number of grazers in False Bay. The occurrence of a higher cover of encrusting corallines in the Bay is probably a consequence of the higher grazing pressure. Distinct community types can be recognized from TWINSPAN and CCA."

"" "Marine Pollution Bulletin" "" "2007" "55" "" "" "" "" "" "" "The EC Water Framework Directive (WFD) suggests using abundance and species composition of intertidal seaweed communities for ecological quality classification of rocky seashores. There are two difficulties with this. According to WFD all sensitive species should be present on a shore. There is no accepted list of sensitive seaweed species and those which may be sensitive in one location may not be so in another. Second, natural successions can result in very large abundance changes of common species, e.g. from almost completely fucoid-dominated shores to almost totally barnacle-dominated shores, without any change in ecological quality. Studies have shown that numerical species richness, not the list of actual species present, is broadly constant in the absence of disturbance. The ephemeral species, possibly the sensitive members of the community, change regularly in such a way as to conserve species richness. It is proposed that species richness on a defined length of shore be used as a criterion of ecological quality. A database of species found on over 300 shores in the British Isles, under strictly controlled sampling conditions, has given ranges of values of species richness to be expected and has allowed for variations in these values due to sub-habitat variability, wave exposure and turbidity to be factored in. A major problem in applying such a tool is the lack of expertise of many workers in critical identification of seaweed species. A reduced species list has been extracted from the database using species commonly present and identifiable with reasonable certainty. A numerical index of ecological quality is proposed based on scores for various aspects of the physical nature of the habitat combined with a score for species richness which may be based on the reduced species list. The scoring system also uses further aspects of community structure, such as ecological status groups and the proportions of rhodophyta, chlorophyta and opportunist species. For this system to be effective there has to be close control of the way in which sampling is carried out to ensure a uniform level of thoroughness." "WRRL" "" "D" "Kusakin, O. G."
