Based on a literature survey, we evaluated the periods of cyanobacterial dominance in Brazil. We hypothesized that variability of environmental forces along the country will promote or facilitate temporal and spatial mosaic in cyanobacterial dominance. The most striking outcomes are related to the dominance of Cylindrospermopsis, Dolichospermum, and(More)
Toxicity and morphology may function as defense mechanisms of bloom-forming cyanobacteria against zooplankton grazing. Yet, the relative importance of each of these factors and their plasticity remains poorly known. We tested the effects of chemical and morphological traits of the bloom-forming cyanobacterium Cylindrospermopsis raciborskii on the feeding(More)
Toxic effects of freshwater cyanobacteria on mesozooplankton partially depend on the feeding strategies, generalist (cladocera) or selective filter-feeders (copepod) and on the type of toxin. Blooms of Cylindrospermopsis raciborskii (Nostocales) are increasingly more common in freshwaters. It can produce neurotoxins (paralytic shellfish poison, PSP),(More)
