Minireviews:
Bernabé Santelices. Recent advances in fertilization ecology of macroalgae. J. Phycol. 2002 38:
4-10.
Our understanding of natural patterns of fertilization in seaweeds has increased substantially over the last 10
years due to new approaches and methods to characterize the nature and frequency of fertilization processes in situ, to
recognize the conditions and mechanisms enhancing fertilization success, and to anticipate population and community
consequences of the patterns of natural fertilization. Successful reproduction in many species depends on a delicate
juxtaposition of abiotic and biotic conditions. Important abiotic factors are those triggering gamete release (e.g. single or
interacting effects of light quality and water movement) and those affecting gamete viability or concentrations (e.g.
salinity effects on polyspermy blocks; gamete dilution due to water movement). Examples of important biotic
components are synchronous gamete release, efficiency of polyspermy-blocking mechanisms, population density of
sexually fertile thalli, interparent distances, and male-to-female ratios. Field data indicate fertilization frequencies of
70%–100% in broadcasting-type seaweeds (e.g. fucoids) and 30%–80% in brooding-type (red) algae. Red algal values
are higher than previously thought and challenge presently accepted explanations for their complex life histories.
Important population and community questions raised by the recent findings relate to the magnitude of gene flow and
exchange occurring in many micropopulations that seemingly breed during periods of isolation, the physiological basis
and population effects of male-to-male competition and sexual selection during fertilization of brooding seaweeds, and
the effects of massive gamete release, especially in holocarpic seaweeds, on benthic and planktonic communities.
Comparative studies in other algal groups are now needed to test the generality of the above patterns, to provide critical
pieces of information still missing in our understanding of natural fertilization processes, and to elucidate the
evolutionary consequences of the different modes of reproduction (e.g. brooders vs. broadcasters). ABSTRACT.
John A. Raven and Janet E. Kübler. New light on the scaling of metabolic rate with the size of
algae. J. Phycol. 2002 38: 11-16.
The scaling of metabolic rate with the size of algae has been discussed and researched at length. The observation
that algae usually have exponents b in the equation R = a·W-b (where R is the specific growth rate, W is the organism
[cell] biomass, and a and b are constants) equal to or higher than the value of -0.25 for many other organisms is
generally related to resource-saturated (maximal) values of R. Recent work has shown that the exponent b for lightlimited growth is more negative than -0.25. This was predicted from considerations of the package effect in photon
absorption, as modulated by the volume-specific pigment content of the cells, and the photosynthetic unit size. Further
work is needed to extrapolate these findings to fluctuating light environments. This minireview puts the recent work into
a broader context and suggests how further work could quantify the roles of optical thickness and of spatial and
temporal variations in the radiation field in determining metabolic rates. ABSTRACT.
Reviews:
Hugh L. MacIntyre, Todd M. Kana, Tracy Anning, and Richard J. Geider. Photoacclimation of
photosynthesis irradiance response curves and photosynthetic pigments in microalgae and
cyanobacteria. J. Phycol. 2002 38: 17-38.
The photosynthesis-irradiance response (PE) curve, in which mass-specific photosynthetic rates are plotted
versus irradiance, is commonly used to characterize photoacclimation. The interpretation of PE curves depends critically
on the currency in which mass is expressed. Normalizing the light-limited rate to chl a yields the chl a-specific initial
slope (αchl). This is proportional to the light absorption coefficient (achl), the proportionality factor being the photon
efficiency of photosynthesis (øm). Thus, α chl is the product of achl and øm. In microalgae αchl typically shows little
(<20%) phenotypic variability because declines of øm under conditions of high-light stress are accompanied by
increases of achl. The variation of αchl among species is dominated by changes in achl due to differences in
pigment complement and pigment packaging. In contrast to the microalgae, α chl declines as irradiance increases in the
cyanobacteria where phycobiliproteins dominate light absorption because of plasticity in the phycobiliprotein:chl a
ratio. By definition, light-saturated photosynthesis (Pm) is limited by a factor other than the rate of light absorption.
Normalizing P m to organic carbon concentration to obtain P mC allows a direct comparison with growth rates. Within
species, PmC is independent of growth irradiance. Among species, P mC covaries with the resource-saturated growth rate.
The chl a:C ratio is a key physiological variable because the appropriate currencies for normalizing light-limited and
light-saturated photosynthetic rates are, respectively, chl a and carbon. Typically, chl a:C is reduced to about 40% of its
maximum value at an irradiance that supports 50% of the species-specific maximum growth rate and light-harvesting
accessory pigments show similar or greater declines. In the steady state, this down-regulation of pigment content
prevents microalgae and cyanobacteria from maximizing photosynthetic rates throughout the light-limited region for
growth. The reason for down-regulation of light harvesting, and therefore loss of potential photosynthetic gain at

moderately limiting irradiances, is unknown. However, it is clear that maximizing the rate of photosynthetic carbon
assimilation is not the only criterion governing photoacclimation. ABSTRACT.

Printzina (Trentepohliales, Chlorophyta) in urban habitats in western Ireland. J. Phycol. 2002
38: 39-54.
On the basis of field and culture investigations, five species of the genera Trentepohlia and Printzina were found
to occur in urban habitats in western Ireland: Trentepohlia abietina (Flotow) Hansgirg, T. aurea (Linnaeus) Martius, T.
iolithus (Linnaeus) Wallroth, T. cf. umbrina (Kützing) Bornet, and Printzina lagenifera (Hildebrandt) Thompson et
Wujek. These species formed perennial populations on a variety of substrata. T. abietina occurred on bark of trees; T. cf.
umbrina occurred on stone walls; and P. lagenifera grew on several substrata, mainly cement and asbestos sheeting. T.
aurea and T. iolithus were found on old concrete and cement walls; in particular, the latter species formed characteristic,
extensive, deep-red patches on many buildings. In culture, best growth and reproduction of these species were observed
at 10 and 15° C, 16:8 h light:dark. Both in culture and in the field, reproduction took place by release of biflagellate
swarmers behaving as asexual spores, germinating to produce new plants without any evidence of sexual fusion; release
of biflagellate swarmers in the field was generally observed in all seasons throughout a whole annual cycle.
Confirmation of the occurrence of sexual reproduction in Trentepohlia was not obtained. ABSTRACT.

(Bacillariophyceae) species in inland embayments and outer coastal waters of Washington
state, USA. J. Phycol. 2002 38: 55-65.
Plankton samples from three inland embayments and several outer coastal sites of Washington State were
collected from 1997 through 1999 and were examined for the presence of diatoms of the genus Pseudo-nitzschia and
levels of the toxin, domoic acid (DA). Seven species were observed, including Pseudo-nitzschia pungens (Grunow ex
Cleve) Hasle, P. multiseries (Hasle) Hasle, P. australis Frenguelli, P. fraudulenta (Cleve) Hasle, P. cf. heimii Manguim,
P. pseudodelicatissima (Hasle) Hasle, and P. delicatissima (Cleve) Heiden. The coastal Pseudo-nitzschia species
assemblages differed significantly from those observed within embayments. The dominant species observed at coastal
sites were P. pseudodelicatissima and P. cf. heimii. Pseudo-nitzschia assemblages found in embayments included one or
more of the following species: P. pungens, P. multiseries, P. australis, P. pseudodelicatissima, and P. fraudulenta. The
nuclear large subunit rRNA gene was sequenced for six of the seven species identified. This sequence revealed that P.
multiseries, P. pungens, P. australis, and P. heimii were genetically similar to those found in California, whereas P.
delicatissima and P. pseudodelicatissima were distinct from the California isolates. Although the concentrations of DA
in razor clams along Washington State coasts have exceeded regulatory limits several times since 1991, levels of DA in
shellfish from Washington State embayments have not yet exceeded regulatory limits. The widespread presence of
toxin-producing Pseudo-nitzschia species suggests, however, that toxic blooms are likely to occur within embayments in
the future. In conjunction with the monitoring of environmental conditions conducive to toxic bloom formation, the
development of species-specific probes for rapid and accurate detection of potentially toxic Pseudo-nitzschia species in
this region would enable the forecasting of a toxic event before DA accumulates in shellfish, thereby reducing the
impacts to coastal communities. ABSTRACT.
Ilka Schönfelder, Jörg Gelbrecht, Jörg Schönfelder, and Christian E. W. Steinberg. Relationships
between littoral diatoms and their chemical environment in Northeastern German lakes and
rivers. J. Phycol. 2002 38: 66-89.
We explored statistical relationships between the composition of littoral diatom assemblages and 21 chemical
and physical environmental variables in 69 lakes and 15 river sites in the lowland of northeastern Germany. Canonical
correspondence analysis with single treatment and with forward selection of environmental variables was used to detect
11 important ecological variables (dissolved inorganic carbon [DIC], Na+, total phosphorus [TP], dissolved organic
carbon [DOC], total nitrogen [TN], pH, oxygen saturation, dissolved iron, SO42-, NH4+, soluble reactive silicium) and
maximum water depth or Ca2+ or soluble reactive phosphorus that most independently explain major proportions of the
total diatom variance among the habitats. Monte Carlo permutation tests showed that each contributed a significant
additional proportion (P < 0.05) of the variance in species composition. Together, these 11 most important
environmental variables explained 34% of the total variance in species composition among the sites and captured 73%
of the explained variance from the full 21 parameters model. Weighted-averaging regression and calibration of 304
indicator taxa with tolerance down-weighting and classic deshrinking was used to develop transfer functions between
littoral diatoms and DIC, pH, TP, TN, and Cl-. The DOC:TP ratio was introduced and a weighted-averaging model was
developed to infer allochthonous DOC effects in freshwater ecosystems. This diatom-DOC/TP model was significant (P
< 0.001) and explained 7.6% of the total diatom variance among the sites, surpassing the inferential power of the
diatom-TP-transfer function (7.3% explained variance). The root-mean-square errors of prediction of the models were

estimated by jack-knifing and were comparable with published data sets from surface sediment diatom samples. The
data set of littoral diatoms and environmental variables allows use of the diatom-environmental transfer functions in
biomonitoring and paleolimnological approaches across a broad array of natural water resources (such as floodplains,
flushed lakes, estuaries, shallow lakes) in the central European lowland ecoregion. ABSTRACT.

of periphyton assemblages in relation to environmental gradients in Colorado Rocky
Mountain streams. J. Phycol. 2002 38: 83-95.
We assessed relationships between chemical and physical characteristics and periphyton assemblages in stream
reaches of the mineral belt in the Southern Rockies ecoregion of Colorado, United States. Using canonical ordination
analyses, we contrasted results wherein assemblage structure was assessed using community metrics or species
abundances. Our objectives were to identify community metrics or individual species diagnostic of the primary
environmental stressors in these streams, to compare the sensitivity of these two approaches to determining the primary
stressors, and to determine how these approaches may be used to differentiate the effects of these environmental
stressors from other gradients. For periphyton metrics, the first axis extracted by redundancy analysis correlated with
total phosphorus, substrate coarseness and embeddedness, and riparian vegetation condition, whereas the second axis
correlated with dissolved metals. For species abundances, the three axes extracted by canonical correspondence analysis
(CCA) were correlated with (1) stream size and types of in-stream habitats; (2) total phosphorus, dissolved ions, and
riparian disturbance by agriculture; and (3) sediment coarseness and embeddedness and riparian vegetation condition.
Concentrations of dissolved metals were not correlated with the CCA axes. Analyses of species abundances were
sensitive to effects associated with nutrients, substrates, and riparian vegetation, whereas analyses of periphyton metrics
were sensitive not only to these nutrient and physical habitat effects but also to toxicological effects associated with
metals. As a result, the analyses of periphyton metrics may be used to identify which metrics would be useful for a
periphyton index of biotic integrity and would also be individually diagnostic of the larger scale stressors in these
streams, nutrient, substrate, and riparian vegetation effects of livestock grazing and increased metal concentrations
associated with metal mining. ABSTRACT.

Lay Ming Teo. Singapore isolates of the Dinoflagellate Gymnodinium catenatum (Dinophyceae)
produce a unique profile of paralytic shellfish poisoning toxins. J. Phycol. 2002 38: 96-106.
We investigated the cell morphology, toxicity and toxin composition, and rDNA sequences of clonal cultures of
the chain-forming dinoflagellate Gymnodinium catenatum H.W.Graham isolated from the port of Singapore. The cell
morphology was consistent with most descriptions of this species except for sparsely distributed putative trichocyst
pores visible on some cells under SEM. Nucleotide sequences (697 base pair) of the D1–D2 conserved regions and
intervening variable domain of the large subunit rDNA were identical among isolates from Singapore and those of all
other global populations examined so far (from Australia, China, Japan, Korea, New Zealand, Spain, and Uruguay), and
this is consistent with the morphological conservatism of the species. Among isolates of G. catenatum that produce
toxins associated with paralytic shellfish poisoning, the cellular toxicity of Singapore clones, as determined by
intraperitoneal mouse bioassay (30–50 pg saxitoxin equivalents·cell-1) and immunoassay (24 ± 8 saxitoxin
equivalents·cell-1) was relatively high. The mouse bioassay toxicity was comparable with that of Spanish and Philippine
isolates that have undergone acid hydrolysis. However, analysis of toxin composition of Singapore clones by HPLC
with fluorescence detection or HPLC-mass spectrometry/mass spectrometry revealed a unique toxin profile that was
dominated by the highly potent carbamate toxins, primarily gonyautoxin (GTX) 1 and 4 with lesser amounts of GTX2,
GTX3, neosaxitoxin, and saxitoxin. No N - sulfocarbamoyl, decarbamoyl, or deoxy-decarbamoyl toxins were detected.
In contrast, less potent N - sulfocarbamoyl toxins dominate the toxin profiles of all other global populations examined to
date (from Australia, China, Japan, New Zealand, the Philippines, Portugal, Spain, and Uruguay). The lack of genetic
diversity found among broadly distributed populations of G. catenatum is consistent with the hypothesis of a relatively
recent global spread of this species. Yet the unique toxin profile of Singapore strains indicates that it is unlikely that this
strain has been recently translocated from any of the populations with characterized toxin profiles. In any case, the
unique carbamate-dominated toxin profile may be a useful signature to identify the potential spread of this strain from
the port of Singapore, one of the world's busiest. ABSTRACT.

monitoring by a bioluminescent cyanobacterial sensor strain. J. Phycol. 2002 38: 107-115.
Phosphorus (P) is widely considered to be the main nutrient limiting the productivity of freshwater
phytoplankton, but an assessment of its bioavailability in natural samples is highly complex. In an attempt to provide a
novel tool for this purpose, the promoter of the alkaline phosphatase gene, phoA, from Synechococcus sp. PCC 7942
was fused to the luxAB luciferase genes of the bioluminescent bacterium Vibrio harveyi. The resulting construct was
introduced into a neutral site on the Synechococcus sp. PCC 7942 genome to yield strain APL, which emitted light when

inorganic P concentrations fell below 2.3 µM. Light emission of P-deprived cells decreased rapidly upon inorganic P
readdition. The reporter was demonstrated to be a sensitive tool for monitoring the bioavailability of both inorganic and
organic P sources. In water samples taken from a natural freshwater environment (Lake Kinneret, Israel), the
luminescence measured correlated with total dissolved phosphate concentrations. ABSTRACT.

hydrophobicity and light on spore settlement in the brown alga Hincksia irregularis
(Phaeophyceae). J. Phycol. 2002 38: 116-124.
We examined the effects of light and surface hydrophobicity individually and in tandem on Hincksia irregularis
(Kützing) Amsler spore settlement. Hincksia irregularis spores were determined to be negatively phototactic by the use
of computer-assisted motion analysis. Spore settlement was significantly influenced by surface hydrophobicity and by
light, individually and in tandem. Experiments conducted using culture plates modified to reduce well edge artifacts
revealed significantly higher settlement on hydrophobic surfaces and in dark environments when compared with
negatively charged surfaces and lighted environments. Experimental light/dark boundaries elicited distinct spore
settlement responses, with spores displaying dissimilar settlement patterns on plates with different surface
hydrophobicities. The results of this study indicate H. irregularis spores possess the capacity for complex responses to
their environment. These complex responses may influence dispersal and aid spores in the detection of suitable
settlement locations in marine microenvironments. ABSTRACT.

Kühl. Apparent light requirement for activation of photosynthesis upon rehydration of
desiccated beachrock microbial mats. J. Phycol. 2002 38: 125-134.
Photosynthetic electron transport of beachrock microbial mats growing in the intertidal zone of Heron Island
(Great Barrier Reef, Australia) was investigated with a pulse amplitude modulation chl fluorometer providing four
different excitation wavelengths for preferential excitation of the major algal groups (cyanobacteria, green algae,
diatoms/dinoflagellates). A new type of fiberoptic emitter-detector unit (PHYTO-EDF) was used to measure chl
fluorescence at the sample surface. Fluorescence signals mainly originated from cyanobacteria, which could be almost
selectively assessed by 640-nm excitation. Even after desiccation for long time periods under full sunlight, beachrock
showed rapid recovery of photosynthesis after rehydration in the light (t1/2 ≈15 min). However, when rehydrated in the
dark, the quantum yield of energy conversion of PSII remained zero over extended periods of time. Parallel
measurements of O2 concentration with an oxygen microoptode revealed zero oxygen concentration in the surface layer
of rehydrated beachrock in the dark. Upon illumination, O2 concentration increased in parallel with PSII quantum yield
and decreased again to zero in the dark. It is proposed that oxygen is required for preventing complete dark reduction of
the PSII acceptor pools via the NADPH-dehydrogenase/chlororespiration pathway. This hypothesis is supported by the
observation that PSII quantum yield could be partially induced in the dark by flushing with molecular oxygen.
ABSTRACT.
Mariachiara Naldi and Patricia A. Wheeler. 15N measurements of ammonium and nitrate uptake
by Ulva fenestrata (Chlorophyta) and Gracilaria pacifica (Rhodophyta): comparison of net
nutrient disappearance, release of ammonium and nitrate, and 15N accumulation in algal
tissue. J. Phycol. 2002 38: 135-144.
Ammonium and nitrate uptake rates in the macroalgae Ulva fenestrata (Postels and Ruprecht) (Chlorophyta) and
Gracilaria pacifica (Abbott) (Rhodophyta) were determined by 15N accumulation in algal tissue and by disappearance
of nutrient from the medium in long-term (4–13 days) incubations. Nitrogen-rich algae (total nitrogen > 4% dry weight
[dw]) were used to detect isotope dilution by release of inorganic unlabeled N from algal thalli. Uptake of NH4+ was
similar for the two macroalgae, and the highest rates were observed on the first day of incubation (45 µmol N·g dw-1·h-1
in U. fenestrata and 32 µmol N·g dw-1·h-1 in G. pacifica). A significant isotope dilution (from 10 to 7.9 atom %
enrichment) occurred in U. fenestrata cultures during the first day, corresponding to a NH 4+ release rate of 11 µmol N·g
dw-1·h-1. Little isotope dilution occurred in the other algal cultures. Concurrently to net NH4+ uptake, we observed a
transient free amino acid (FAA) release on the first day in both macroalgal cultures. The uptake rates estimated by NH4+
disappearance and 15N incorporation in algal tissue compare well (82% agreement, defined as the percentage ratio of the
lower to the higher rate) at high NH4+ concentrations, provided that isotope dilution is taken into account. On average,
96% of added 15NH4+ was recovered from the medium and algal tissue at the end of the incubation. Negligible uptake of
NO3- was observed during the first 2–3 days in both macroalgae. The lag of uptake may have resulted from the need for
either some N deprivation (use of NO3- pools) or physiological/metabolic changes required before the uptake of NO3-.
During the subsequent days, NO3- uptake rates were similar for the two macroalgae but much lower than NH 4+ uptake
rates (1.97–3.19 µmol N·g dw-1·h-1). Very little isotope dilution and FAA release were observed. The agreement
between rates calculated with the two different methods averaged 91% in U. fenestrata and 95% in G. pacifica.
Recovery of added 15NO3- was virtually complete (99%). These tracer incubations show that isotope dilution can be
significant in NH4+ uptake experiments conducted with N-rich macroalgae and that determination of 15N atom %

enrichment of the dissolved NH4+ is recommended to avoid poor isotope recovery and underestimation of uptake rates.
ABSTRACT.
Kalle Olli and Donald M. Anderson. High encystment success of the dinoflagellate Scrippsiella
cf. lachrymosa in culture experiments. J. Phycol. 2002 38: 145-156.
Close to 100% encystment efficiency and a yield above 10 5 cysts·mL-1 were routinely achieved in full strength
f/2 medium-based batch cultures (883 µM NO3- and 36 µM PO4-3) of the marine dinoflagellate Scrippsiella cf.
lachrymosa Lewis. Increases in cell density led to nutrient depletion in this enriched medium, which was the most likely
cause for initiation of cyst formation. Lowering the concentration of either nutrient to 1/10 the initial levels decreased
the encystment efficiency, whereas use of ammonium as the N source resulted in both low cell yield and low
encystment efficiency. The mandatory dormancy period was ca. 60 days and was not affected by cold dark storage of
the cysts. Cysts produced in the initial phase of sexual reproduction were relatively large (length 47 µm, width 31 µm)
with a heavy calcareous cover. Cysts produced thereafter lacked apparent calcareous cover and were smaller (length 29
µm, width 19 µm). The decrease of cyst volume (by a factor of 0.24–0.4) suggested strong resource limitation during the
course of encystment. However, after the mandatory dormancy period, germination success of the smaller cysts was
higher (80%), compared with the larger cysts that had been produced initially (50%). Germling survival (74%) was
independent of cyst type but was enhanced by higher nutrient concentration during incubation. The ratio of initial
nutrient concentration in the medium to the cyst yield was used as a proxy to estimate the cellular nutrient quota. The
conservative estimates of 9 pmol N·cyst-1 and 0.4 pmol P·cyst-1 obtained in this manner are at the low end of the range
of previous published estimates for other dinoflagellate cysts. Given the high encystment observed in laboratory
experiments, we have no reason to assume an inherently lower encystment success in dinoflagellate field populations.
Our results do not challenge the low nutrient paradigm for dinoflagellate sexuality. We believe that the high encystment
success and cyst yield of this particular species is at least partly due to its ability to achieve very high cell densities in
cultures, which evidently leads to nutrient depletion even in f/2 medium. ABSTRACT.
Virginia M. Weis, E. Alan Verde, and Wendy S. Reynolds. Characterization of a short form
peridinin-chlorophyll-protein (PCP) cDNA and protein from the symbiotic dinoflagellate
Symbiodinium muscatinei (Dinophyceae) from the sea anemone Anthopleura elegantissima
(Cnidaria). J. Phycol. 2002 38: 157-163.
Peridinin-chl-proteins (PCPs) are highly abundant light harvesting pigment proteins unique to the photosynthetic
dinoflagellates. Although extensive studies have examined PCP proteins, only four complete pcp nucleotide sequences
have been reported to date. PCPs occur in two different forms, a short form with a molecular mass of 14–16 kDa and a
long form with a mass of 30–35 kDa, which is thought to have arisen by a gene duplication event. This study describes
PCP and its cDNA from Symbiodinium muscatinei (LaJeunesse and Trench), a symbiotic dino-flagellate resident in the
sea anemone Anthopleura elegantissima (Brandt). Two-dimensional PAGE of S. muscatinei proteins revealed numerous
strongly staining spots at a molecular mass of 15.7 and varying pIs. The N-terminal peptide sequence from one of these
spots could be successfully aligned with PCPs from other dinoflagellates, and a complete cDNA sequence was
generated by reverse transcriptase PCR, using primers based on the peptide sequence. Northern analyses of RNA
revealed a single 1.0-kb band, suggesting that only the short form of the gene is expressed. The S. muscatinei pcp
predicted amino acid sequence displayed a 50%–70% identity with the other known pcp sequences. Interestingly, S.
muscatinei PCP was best aligned with the only other short form sequence known, that from Heterocapsa pygmaea, and
not with the long form from the congener Symbiodinium sp. from the coral Acropora formosa. Phylogenetic analysis of
the five pcp sequences suggests that the PCP gene family is divided into two distinct clades, a short form and a long
form, and indicates the existence of two separate genes for the two forms. ABSTRACT.

regeneration of protoplasts from disintegrated cells of the multicellular marine green alga
Microdictyon umbilicatum (Chlorophyta). J. Phycol. 2002 38: 174-183.
Protoplast regeneration from extruded cytoplasm of the multicellular marine green alga Microdictyon
umbilicatum (Velley) Zanardini (Cladophorales, Anadyomenaceae) was investigated. The early process of protoplast
formation is comprised of two steps: agglutination of cell organelles into protoplasmic masses followed by generation of
a temporary enclosing envelope around them. Agglutination of cell organelles was mediated by a lectin–carbohydrate
complementary system. Three sugars, D-galactosamine, D-glucosamine, and α-D-mannose, inhibited the agglutination
process, and three complementary lectins for the above sugars, peanut agglutinin, Ricinus communis agglutinin, and
concanavalin A, bound to the surfaces of chloroplasts. Agglutination assay using human erythrocytes showed the
presence of lectins specific for the above sugars in the algal vacuolar sap. A fluorescent probe 1-(4trimethylammoniumphenyl)-6-phenyl-a, 3,5-hexatriene revealed that the envelope initially surrounding protoplasts was
not a lipid-based cell membrane. However, this developed several hours later. Simultaneous fluorescein diacetate and
propidium iodide staining showed that the primary envelope had some characteristics of cell membranes, such as
ALGOLOGICAL NEWSLETTER (Kiev)
№ 16 FEBRUARY 2002
semipermeability and selective transport of materials. Also, fluorescein diacetate staining showed esterase activity in the
protoplast and relocation of cell organelles and compartmentalization of cytoplasm during the process of regeneration.
Both pH 7–9 and salinity 400–500 mM were found to be essentially important for the development of the protoplast
envelope. When the basic regeneration process was accomplished, two alternative pathways of development were seen;
about 70% of one-celled protoplasts transformed into reproductive cells within 2 weeks after wounding, whereas others
began cell division and grew into typical Microdictyon thalli. Quadriflagellate swarmers were liberated from the
reproductive cells, and they germinated into mature individuals. It is therefore suggested that this species may use the
wound response as a method of propagation and dispersal. ABSTRACT.

cell nuclear antigen gene from the coccolithophorid Pleurochrysis carterae (Haptophyceae). J.
Phycol. 2002 38: 164-173.
The gene encoding proliferating cell nuclear antigen (PCNA) was isolated from the marine coccolithophorid
microalga Pleurochrysis carterae (Braarud et Fagerland) Christensen (Haptophyceae). Two mRNAs (Pcpcna1 and
Pcpcna2) were identified and contained an identical coding region for 222 amino acid residues and an untranslated
sequence of 302 base pair (Ut1) and 246 base pair (Ut2), respectively. Comparison between PCR-derived genomic DNA
fragments and cDNA sequences revealed five introns. The coding region of Pcpcna is similar to counterparts in other
organisms and contains highly conserved functional domains. Phylogenetic analyses indicated clustering of Pcpcna with
pcna in its haptophyte relative Isochrysis galbana Parke. A recombinant fusion protein of Pcpcna, overexpressed in
Escherichia coli, was recognized by the PC10 antibody against rat PCNA. Using RT-PCR and Western blotting, Pcpcna
was found to be highly transcribed and translated during the exponential growth phase relative to the stationary growth
phase, with a positive correlation between gene expression and growth rate. It can be concluded that the pcna is
conserved in this coccolithophorid phytoplankton and that its expression is growth stage related. ABSTRACT.
Phylogenetics and Taxonomy:
Louise E. Phillips. Taxonomy and molecular phylogeny of the red algal genus Lenormandia
(Rhodomelaceae, Ceramiales). J. Phycol. 2002 38: 184-208.
The genus Lenormandia Sonder is currently composed of nine species from Australia and New Zealand. Some of
these are well known, but others are rare and ill defined. Material of all nine species has been examined and found to fall
into three discrete morphological groups forming highly supported clades on analysis of 18S rDNA sequences. The first
group contains four Australian-endemic species and includes the type species L. spectabilis Sonder. Plants have a cleft
apex that is not inrolled, a distinctive rhombic surface areolation pattern caused by a one- to two-layered medulla of
interlocking cells, lack pseudopericentral cells, and produce their reproductive structures on the blade surfaces. The type
species of the genus Lenormandiopsis, L. latifolia (Harvey et Greville) Papenfuss, was found to belong to this group and
is thus returned to Lenormandia where it was originally placed. Species falling into the other two groups are removed to
new genera that are being described separately. One extremely rare species of Lenormandia from southwestern
Australia is transferred to the delesseriacean genus Phitymophora. ABSTRACT.

Epiglossum Kützing (Rhodomelaceae, Ceramiales). J. Phycol. 2002 38: 209-229.
In a taxonomic/phylogenetic study of the genus Lenormandia, several species were found to differ significantly
from the type species, L. spectabilis Sonder, in apical morphology, blade-surface pattern, medullary construction, the
presence of pseudopericentral cells, and the position of reproductive structures. These species constitute two groups that
differ morphologically, a finding largely supported by analysis of 18S rRNA sequences, as reported previously. The two
putative Lenormandia species from New Zealand, along with two previously undescribed species also from New
Zealand, comprised one such group, designated here by the new genus name Adamsiella L.E. Phillips et W.A. Nelson,
gen. nov. and including A. melchiori L.E. Phillips et W.A. Nelson, sp. nov., A. lorata L.E. Phillips et W.A. Nelson, sp.
nov., A. angustifolia (Harvey) L.E. Phillips et W.A. Nelson, comb. nov., and A. chauvinii (Harvey) L.E. Phillips et W.A.
Nelson comb. nov. Adamsiella differs from Lenormandia by incurved apices, a chevron surface pattern, and
reproductive structures on dorsi-ventrally flattened apically incurved polysiphonous branchlets usually produced at the
margins. Two species endemic to Australia formed the second group designated by the resurrected generic name
Epiglossum and also characterized by a strongly incurved apex and chevron surface pattern but with reproductive
structures produced on terete polysiphonous branchlets found either on the midrib or elsewhere on the blade surface but
not the margins. Epiglossum contains E. smithiae (J.D. Hooker et Harvey) Kützing and E. proliferum (C. Agardh) L.E.

ALGOLOGICAL NEWSLETTER (Kiev)
№ 16 FEBRUARY 2002
Microcystis aeruginosa is a common form of cyanobacteria (blue-green algae) capable of forming toxic
heptapeptides (microcystins) that can cause illness or death. Occasionally, blooms of cyanobacteria have caused toxic
fish-kills in catfish production ponds. We have developed a PCR test that will detect the presence of microcystinproducing cyanobacteria. Microcystin producers are detected by the presence of the microcystin peptide synthetase B
gene (an obligate enzyme in the microcystin pathway), which appears to be present only in toxin-producing
cyanobacteria. These PCR amplifications can be performed in multiplex using purified DNA from pond waters or by
two-stage amplification from native water samples. A synoptic survey of 476 channel catfish production ponds from
four states in the southeastern United States revealed that 31% of the ponds have the genetic potential to produce
microcystins by toxic algae. ABSTRACT.

Dear colleague!
This is a late call for the following workshop, the registration deadline for which has now been
extended to 28 February. Although the workshop is primarily intended for PhD students, we can
accept registration from non-students interested in broadening their knowledge about freshwater
science (particularly those in the early part of their careers).
INTERNATIONAL POSTGRADUATE WORKSHOP:
CURRENT ISSUES IN LIMNOLOGY
Castle Head Field Centre, Grange-over-Sands, Cumbria, U.K. 8 - 13 April 2002
Organised by The Freshwater Biological Association
This is the first in a proposed series of annual FBA postgraduate workshops. Led by
internationally renowned experts, it aims to develop students' understanding of some of the key
issues in current limnological research, and to provide a forum for the exchange of ideas with
workshop-leaders and fellow students. The workshop environment will also help students build
transferable skills in presentation, synthesis and communication.
The workshop will focus on three topical themes:
1. Exploring limnology: the physico-chemical constraints upon the biological transformation
in lakes (led by Colin Reynolds and Glen George, Centre for Ecology and Hydrology Windermere)
2. Dissolved organic matter and its interactions with microbial food webs (led by Lars
Tranvik & Stefan Bertilsson, Uppsala University, Sweden)
3. Using stable isotopes to answer limnological questions (led by Roger Jones, University of
Lancaster and Jill Lancaster, University of Edinburgh).
Each participant will also be required to present a poster and there will be a workshop on
poster presentation skills. The workshop is informal, with plenty of opportunity to discuss ideas
with fellow participants and the course leaders.
Workshop fee covering all accommodation & meals (no tuition fees): FBA Members Ј320, or
Non-Members Ј345 (+ Ј30 for single occupancy of a bedroom, depending on availability). Deadline
for booking: 6 February 2002 - NOW EXTENDED TO 28 FEBRUARY.
The workshop is primarily intended for PhD students, from anywhere in the world, who are
studying freshwater science. However, we are also able to accept non-students (particularly those in
the early part of their career) who wish to broaden their knowledge.
