Diatomáceas planctônicas e de sedimento superficial em represas de abastecimento da Região Metropolitana de São Paulo, SP, Sudeste do Brasil

Abstract: -(Plankton and surface sediment diatoms in water supply reservoirs from the Metropolitan Region of São Paulo, São Paulo State, Southeastern Brazil). This study presents and compares the floristic diatom composition of plankton and surface sediments of the water supply reservoirs from the Alto Cotia System (Pedro Beicht and Cachoeira da Graça reservoirs), located in the Reserva Florestal do Morro Grande. Samplings were carried out in seven sites, during the dry and rainy seasons and in the sediment surface duri… Show more

“…The sharing of species between compartments might be associated with the fact that the reservoirs are shallow, hence favored the interaction between the diatoms from different compartments. We found a greater diatom biodiversity in the plankton, in contrast to Almeida & Bicudo (2014) who found a greater biodiversity in the surface sediments. In agreement with Rosini et al (2016), who reported changes in the structure of the phytoplankton in an oligotrophic reservoir, we found that the distribution of species in the reservoirs varied according to environmental factors.…”

“…4-11 µm) do que os atualmente referidos para a população do PEFI. Para São Paulo, a espécie foi ilustrada e descrita por Almeida & Bicudo (2014). Apesar da semelhança desse material com o atualmente estudado, os espécimes identificados pelas autoras acima possuem medidas valvares maiores (compr.…”

“…Além de possuírem ciclo de vida curto e diversidade ao longo de todo o corpo hídrico, apresentam também sensibilidade a alterações e distúrbios ambientais nas características físico, química e biológica e, por isso, respondem rapidamente à estas condições O monitoramento de comunidades biológicas específicas podem funcionar como importante ferramenta para sinalizar alterações das condições limnológicas e hidrológicas (ALMEIDA; BICUDO, 2014;MORESCO et al, 2011).…”
