“…Based on earlier findings, it was suggested that C. raciborskii can benefit from low light intensities (Dokulil & Mayer, 1996;Pa´disak & Reynolds, 1998;Bouvy et al, 1999;Briand et al, 2002b;. However, recent experimental studies on tropical and temperate C. raciborskii isolates showed no significant differences in growth rates at different light intensities (Briand et al, 2004).…”

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.

“…Cyanobacterial dominance is mostly related to favourable bottom-up factors (Briand et al 2002, Marinho & Huszar 2002), since they are widely known for their ability to minimize grazing pressure, through different effects on zooplankton community: mechanical interference (difficulty in manipulating and ingesting large colonies or filaments), assimilation (low amounts of essential nutrients) and toxicity (De Bernardi & Giussani 1990). However, some zooplankton species have developed physiological resistance to cyanotoxins (Fulton & Paerl 1988) or behavioural adaptations to avoid toxic cells (Reinikainen et al 1998).…”

“…No chemical changes were observed between Periods I and II, and most of the changes (decrease in nutrients, increase in pH and decrease in light linked to the algae self-shading) were a consequence of the bloom. Low CO 2 and high pH are able to promote or allow cyanobacterial dominance (Shapiro 1990, Caraco & Miller 1998 and many studies have reported a direct relationship between high pH and cyanobacterial biomass (Briand et al 2002). However, the significance of pH as a cause or consequence of cyanobacterial blooms is still not well defined.…”

Trends in recent years have indicated that cyanobacterial blooms in tropical reservoirs are increasing in frequency, magnitude and geographical distribution. Funil Reservoir in southeastern Brazil has experienced eutrophication in the recent decades, resulting in lasting and intense toxic cyanobacterial blooms. As input of nutrients is high during the year, the aim of the present study was to evaluate the role of other variables related to changes in cyanobacterial biomass and composition. The dominant group found over the entire study period was Cyanobacteria (97% of total biomass), which contributed to low diversity. A shift of nitrogen-fixing (Anabaena circinalis and Cylindrospermopsis raciborskii) and non nitrogen-fixing (Microcystis aeruginosa) cyanobacteria was observed. Redundancy analysis indicated that physical factors such as temperature, changes in the mixing zone and light intensity were the main driving factors of the seasonal succession. Nitrogenfixing cyanobacteria dominated in periods of low light in the deepest mixing zone, and also seemed to have experienced stronger grazing effects as the density of the large zooplankton group was related to cyanobacteria biomass. M. aeruginosa bloomed in warm stratified waters, high water levels and during months with more daylight, when the zooplankton density was drastically reduced. Although the long-standing dominance of cyanobacteria may be related to high nutrient availability, the present study showed that under high and constant input of nutrients, other factors, especially physical variables, present a more plausible explanation to promote changes in species composition.KEY WORDS: Cyanobacterial bloom · Cylindrospermopsis · Microcystis · Anabaena · Zooplankton Resale or republication not permitted without written consent of the publisherAquat Microb Ecol 57: [137][138][139][140][141][142][143][144][145][146][147][148][149] 2009 reports of surface scum have become much more numerous since the mid-20th century. Harmful algal blooms caused by cyanobacteria (CyanoHABs) are one of the most severe problems in freshwater ecosystems nowadays. These often-toxic blooms and the dense surface scums are indicative of water quality deterioration and food-web changes, and can be responsible for the mortality of fish, domestic animals and even humans (Paerl & Huisman 2009).Cyanobacteria blooms occur in waters during calm stratified conditions with high temperatures and adequate nutrient supplies (Huszar et al. 2000). Cyanobacterial dominance is mostly related to favourable bottom-up factors (Briand et al. 2002, Marinho & Huszar 2002, since they are widely known for their ability to minimize grazing pressure, through different effects on zooplankton community: mechanical interference (difficulty in manipulating and ingesting large colonies or filaments), assimilation (low amounts of essential nutrients) and toxicity (De Bernardi & Giussani 1990).

“…Cylindrospermopsis raciborskii is highly tolerant of a range of salinity and nutrient concentrations and can grow in temperate climates under light and temperature regimes different from those of tropical environments (Briand et al 2002). These factors make it difficult to predict the distribution and proliferation of this species.…”

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.
