Zooplankton communities as eutrophication bioindicators in tropical reservoirs

Abstract: Eutrophication is a process characterized by an increase in the aquatic system productivity, which causes profound changes in the structure of its communities. Owing to the high environmental sensitivity of planktonic species, the study of their communities can indicate the deterioration of the environment. The Jaguari and Jacareí reservoirs are part of the Cantareira System, supplying water to Sã o Paulo inhabitants and that has been affected by several forms of continuous human interference.Here we analyze s… Show more

“…High rotifer abundance (Almeida et al 2009;Lodi et al, 2011;Špoljar, 2013) in eutrophic waters attributed to the avaliable food (phytoplankton, bacteria, and especially detritus) for rotifers and also their short generation times (Sed'a and Devetter, 2000;Nogueira, 2001, Gazonato Neto et al, 2014, Haberman and Haldna, 2014. When all data and statistical results of the present study are evaluated, the dominance of rotifers in both density and diversity are related with trophic status of the studied reservoirs.…”

“…In this study, seasonal changes in abundance were observed for microcrustaceans (cladocerans and copepods) in the COR, ITU, and PCO reservoirs, with lower values in the rainy season. These decreases in abundance may have resulted from the dilution effect of a higher volume of rainwater, and partially by the removal of these populations at the outlets downstream of these reservoirs (Gazonato-Neto et al, 2014). Some authors (Bonecker et al, 2001;Takahashi et al, 2009) also observed a lower abundance of microcrustaceans during the rainy period in the COR reservoir.…”

“…Pesquisas sobre o zooplâncton são realizadas desde a década de 1970no Brasil (Matsumura-Tundisi & Tundisi, 1976Nordi & Watanabe, 1978;Matsumura-Tundisi et al, 1989). Destacam-se os trabalhos sobre qualidade ambiental e eutrofização (Matsumura- Tundisi & Tundisi, 2005;Sendacz et al, 2006;Sousa et al 2008;Loureiro et al, 2011;Zaganini et al, 2011;Souza et al, 2013, Gazonato-Neto et al, 2014Araújo & Nogueira, 2016). A proposta desse trabalho foi verificar se há diferenças na composição do zooplâncton de acordo com o gradiente de eutrofização e quais fatores ambientais são responsáveis pela variação da distribuição das espécies.…”
