Abstract: 1. Equilibrium and non-equilibrium hypotheses have often been used to explain observations in community ecology. Published case studies have demonstrated that steady state phytoplankton assemblages are more likely to occur in deep lakes than in shallow mixed ones.\ud 2. Phytoplankton seasonal succession was studied by weekly sampling in Faxinal Reservoir (S Brazil), a subtropical deep, clear, warm monomictic and slightly eutrophic reservoir. This study demonstrated an alternation of steady and non-steady state… Show more

“…The relative low abundance of this group can be attributed to the predominant oligotrophic conditions of the larger two first reservoirs and to the prevalent low retention time (non-equilibrium state) (Becker et al, 2008) of the others, except for Capivara, in the cascade. Silva et al (2005) concluded that there is no significant cascading effect on phytoplankton in the reservoirs of the Iguaçu River.…”

“…Williams, 1998;Padisák et al, 2003). Alternatively, long periods with high temperatures may lead to stable environmental conditions, which results in a decrease in diversity due to competitive exclusion of most taxa from the community (Sommer et al, 1993;Naselli-Flores et al, 2003;Becker et al, 2008). These latitudinal For each region, the percentage of lakes in which the genus was found is given Hydrobiologia (2010) 653:79-90 85 differences in generic richness and the underlying factors require further investigation.…”

“…In the reservoirs of the high Paraná River basin, where is located the study area, it was already shown that the influence of the hydrological flow and weather regimes are responsible for the fluctuations in the phytoplankton biomass (Gomes & Miranda 2001). In southeast and south Brazil, transitional zone between tropical-subtropical climate, the seasonal thermal stratification and circulation are also of major importance for the phytoplankton structure (Becker et al 2008).…”
