Influence of phytoplankton fractions on growth and reproduction of tropical cladocerans

Abstract: The influence of two seston fractions, Ͻ 20 m ͑nanoplankton͒ and Ն 20 m ͑microplankton͒, on growth and reproduction of cladoceran species with different sizes, from Lake Monte Alegre, was evaluated through individual growth and life table experiments. Size, shape and other features of the algae in the fractions were described. The procedure of filtering lake water through a 20 m net for seston fractionation caused mutual contamination. The smallest cladoceran species, Ceriodaphnia cornuta Sars and Moina micrur… Show more

“…Different zooplankton groups may have contrasting responses to eutrophication due to, among other factors, differences in reproductive rates (Fileto et al 2004), filtering capacities (Xie et al 1998) and specializations in acquiring food (Schriver et al 1995). Besides, in monitoring studies, different population and community metrics or variates (e.g., density, biomass, species richness, evenness, and diversity of specific groups) may be used as ecological indicators to evaluate the effects of eutrophication or the efficiency of a control program.…”

“…Nesse período ocorre a menor produtividade primária do fitoplâncton, influenciada principalmente por fatores físicos e químicos (Feresin, 2010), mas pouco influenciada pelos fatores bióticos, como controle do zooplâncton sobre o fitoplâncton (Silva, 2004). Além disso, algumas algas existentes no lago são consideradas relativamente mais indigestas (Fileto et al, 2004). A variação temporal do fitoplâncton e a influência do padrão térmico sobre a distribuição vertical das algas no lago foram analisadas por Silva (1995) e Rangel et al (2009) respectivamente.…”

“…Cladóceros filtradores selecionam partículas principalmente pelo tamanho, e, no caso das algas, outras características como forma, dureza da parede celular, bainha gelatinosa, presença de espinhos, tamanho dos filamentos e das colônias, também são considerados (Fileto et al, 2004).…”
