“…Both species are of great concern due to their ability to produce toxins harmful to humans and animals. Planktothrix agardhii is known for producing a variety of microcystins (Carmichael, 1994;Chorus, 2001), while C. raciborskii is able to synthesize the neurotoxin saxitoxin (Lagos et al, 1999;Castro et al, 2004) and the alkaloid hepatotoxin cylindrospermopsin (Ohtani et al, 1992;Li et al, 2001).…”

Biological invasions have attracted particular attention since they often result in serious consequences for natural ecosystems. One planktonic invasive species is Cylindrospermopsis raciborskii, a cyanobacterium originally reported to occur exclusively in the tropics. Over the last few decades its range has extended to temperate regions and it occupies shallow highly eutrophic lakes previously dominated by other cyanobacteria. The purpose of this study was to examine the ecology of C. raciborskii during Planktothrix agardhii blooms in two shallow lakes in western Poland and to determine whether these species have different environmental preferences. Multiple linear regression showed that the biomass of P. agardhii was significantly negatively related to Secchi depth in Lake Bnin´skie. In Lake Bytyn´skie, P. agardhii was significantly positively related to concentrations of PO 3À 4 , chlorophyll a and total phosphorus and negatively related to Secchi depth, NO À 3 , and total nitrogen. Cylindrospermopsis raciborskii was significantly positively related only to concentrations of NH þ 4 . There was a negative correlation between the biomass of P. agardhii and C. raciborskii perhaps showing different responses to environmental variables. Moreover, the biomass of P. agardhii was negatively correlated with Shannon-Wiener diversity of the phytoplankton assemblages. Our results support the concept that these cyanobacterial species have different environmental preferences and their niches differ from each other. These results suggest that light is an important driver of phytoplankton community structure resulting in shifts from a community dominated by P. agardhii in very turbid waters to more diverse communities perhaps including the invasive C. raciborskii in clearer waters.

“…Sua alta competitividade em ambientes eutrofizados, aliada à sua capacidade de formar florações e produzir toxinas, fazem desta espécie uma das Cyanobacterias mais estudadas tanto do ponto de vista ecológico como de saúde pública. Duas das toxinas produzidas são a cilindrospermopsina, um alcalóide com ação no fígado e rins (Ohtani et al 1992, Lagos et al 1999) e a potente toxina paralisante do tipo PSP (Paralytic Shellfish Poisons), que age no sistema neuromuscular (Lagos et al 1999). As florações e a produção de toxinas comprometem a qualidade da água para abastecimento, além de aumentarem consideravelmente os seus custos de tratamento (Carmichael 1996, Codd 2000.…”

-(Cylindrospermopsis raciborskii (Woloszynska) Seenayya & Subba Raju (Cyanobacteria): weekly variation and relation with environmental factors in an eutrophic lake, São Paulo, SP, Brazil). Blooms of Cylindrospermopsis raciborskii have become more and more frequent in Brazilian reservoirs because of its high competitiveness in tropical eutrophic systems. This species is able to produce very aggressive toxins which cause problems to public health and environmental hazards. Our objective was to follow up variations of C. raciborskii density and its relation with the environmental parameters. The studied lake is located in the south of São Paulo city (23º39' S and 46º37' W). It is an eutrophic system with frequent blooms of C. raciborskii. Samples were collected weekly in the deepest part of the lake, from September/97 to September/98. Temperature profile, mixing zone, euphotic zone, pH, conductivity, turbidity, dissolved oxygen, alkalinity, nutrients, chlorophyll a, C. raciborskii density and total phytoplanktonic density were analysed. The ordination of abiotic and biotic data was carried out using Principal Component Analysis (PCA) and Canonical Correspondence Analysis (CCA). During November and December/97 the highest values of C. raciborskii densities were observed. From 12/10 to 12/17, the species contributed with more than 50% to total density. In that period the water column was thermally stratified, temperature and turbidity were high and water transparency decreased. The autumn/winter of 1998 was characterized by the absence of the studied species, by unstratified water column, low water level and temperature, high values of transparency (the highest values observed in the lake) and a great increase in biomass of the macrophyte Eichhornia crassipes (Mart.) Solms. All these relations are presently discussed.Key words -Cyanobacteria, Cylindrospermopsis raciborskii, eutrophic reservoir, weekly variation RESUMO -(Cylindrospermopsis raciborskii (Woloszynska) Seenayya & Subba Raju (Cyanobacteria): variação semanal e relações com fatores ambientais em um reservatório eutrófico, São Paulo, SP, Brasil). Florações de Cylindrospermopsis raciborskii têm sido cada vez mais freqüentes em reservatórios brasileiros em virtude da sua alta competitividade em ambientes tropicais eutrofizados. Esta espécie é produtora de toxinas extremamente agressivas, as quais podem causar problemas de saúde pública e danos ao meio ambiente. Nosso objetivo foi acompanhar a variação temporal da densidade desta população relacionando-a com variáveis ambientais e detectando os possíveis fatores que interferem no seu desenvolvimento. O lago estudado localiza-se na zona sul do Município de São Paulo (23º39' S e 46º37' W). É um corpo d'água eutrofizado e vem apresentando florações freqüentes de C. raciborskii. Amostras de água foram coletadas semanalmente, na parte mais profunda do lago, durante o período de setembro/97 a setembro/98. Foram analisados o perfil térmico, zona de mistura, transparência, zona eufótica, turbidez, pH, alcalini...

Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth 5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand. It formed water blooms at densities >100 000 cells/ml in Lakes Waahi and Whangape. Net rates of population growth >0.2 day -1 were recorded for C. raciborskii in Lakes Ngaroto, Waahi, and Karapiro, based on comparisons of low numbers (detection of <10 cells/ml) from initial samples and its presence at bloom densities (>15 000 cells/ml) in the subsequent sample "x"-"y" days later. C. raciborskii may be well adapted to rapid proliferation in the Waikato lakes, which are eutrophic to hypertrophic, with high light attenuation, and where nitrogen (N) fixation may provide it with a competitive advantage over non-nitrogen fixing algae under N-limited conditions.
