Minireviews:
BernabИ 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. KЭbler. 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 = aћW-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 light-limited 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
(?chl). This is proportional to the light absorption coefficient (achl),
the proportionality factor being the photon efficiency of photosynthesis
(Ьm). Thus, ? chl is the product of achl and Ьm. In microalgae ?chl
typically shows little (<20%) phenotypic variability because declines of Ьm
under conditions of high-light stress are accompanied by increases of achl.
The variation of ?chl among species is dominated by changes in achl due to
differences in pigment complement and pigment packaging. In contrast to the
microalgae, ?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 Pm to organic carbon concentration to obtain PmC
allows a direct comparison with growth rates. Within species, PmC is
independent of growth irradiance. Among species, PmC 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.

Trentepohlia and 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
(KЭtzing) 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 15њ 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.

differences among Pseudo-nitzschia (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.

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.

Kaufmann. Multivariate analysis 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.

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 equivalentsћcell-1) and immunoassay (24 ± 8 saxitoxin
equivalentsћcell-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.

bioavailability 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.

effects of surface 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 (KЭtzing) 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.

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 Nћg dw-
1ћh-1 in U. fenestrata and 32 µmol Nћg dw-1ћh-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 NH4+
release rate of 11 µmol Nћg dw-1ћh-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 NH4+ uptake rates (1.97-3.19 µmol Nћg dw-1ћh-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 105 cystsћmL-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 Nћcyst-1 and 0.4 pmol Pћcyst-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.

Morphology:
Gwang Hoon Kim, Tatiana A. Klotchkova, and John A. West. From protoplasm to
swarmer: 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 ?-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-(4-trimethylammoniumphenyl)-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 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.

the proliferating 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.

gen. nov. and Epiglossum KЭtzing (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) KЭtzing
and E. proliferum (C. Agardh) L.E. Phillips, comb. nov. ABSTRACT.

Techniques:

for microcystin occurrence in channel catfish production ponds. J. Phycol.
2002 38: 230-233.
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 microcystin-producing 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 ?320, or Non-Members ?345 (+ ?30 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
