Comunidade zooplanctônica e sua relação com a qualidade da água em reservatórios do Estado de São Paulo

Abstract: RESUMO: As comunidades zooplanctônicas são importantes componentes na cadeia alimentar considerando os produtores primários e os demais níveis. Além disso, algumas espécies são sensíveis ou tolerantes à poluição orgânica. Aqui testamos a hipótese de que a composição de espécies varia conforme o gradiente de eutrofização. Buscou-se estabelecer os possíveis fatores ambientais responsáveis pela variação na distribuição das espécies. Esse estudo teve como objetivo caracterizar a comunidade zooplanctônica e relacio… Show more

“…In contrast, it was observed that the rotifers K. bostoniensis (invasive species), Keratella spp., H. mira, and P. vulgaris occurred in environments with a high abundance of Cyanobacteria and high levels of TP and TSS in the FUR (rainy and dry periods), MSM (rainy period) and COR (rainy period) reservoirs, and C. unicornis occurred in eutrophic environments in the FUN (rainy and dry periods) reservoir. These species are typical of meso-eutrophic environments and feed on solid suspended particles and colloids derived from bacteria that decompose organic material (Branco et al, 2002;Sousa et al 2008;De-Carli et al 2018). However, even with the trend observed in this study, the use of rotifers as bioindicators must be performed with care, as contrasting results can be found in the literature.…”

“…Rotifers were the organisms that most contributed to the total species richness of the zooplankton. The high diversity of this group in reservoirs has been a recurring pattern in Brazil and is mainly attributed to the opportunistic characteristics of this group (e.g., wide food spectrum, high population turnover) (Takahashi et al, 2009;De-Carli et al, 2018;Picapedra et al, 2020). In turn, great occurrences and abundances of cladocerans (especially B. hagmanni and C. cornuta) and juvenile copepods can be an important indicator of the beginning of the eutrophication process in these reservoirs.…”

“…Além disso, são usados com frequência como modelos ecológicos, já que apresentam limites definidos e conexões claras com ecossistemas adjacentes, sendo capazes de refletir as alterações na paisagem (Blaustein et al, 1999;Vadeboncoeur et al, 2002). Os maiores reflexos dessas alterações podem ser observados, como mudanças na estrutura das comunidades aquáticas associadas a essas poças (De Meester et al, 2005); um exemplo são as populações zooplanctônicas, utilizadas como indicadores dessas mudanças (De-Carli et al, 2018).…”
