Benthic macroinvertebrates as bioindicators of water quality in Billings Reservoir fishing sites (SP, Brazil)

Benthic macroinvertebrates in the Paranapanema reservoir cascade (southeast Brazil).

In this study, the composition, specific richness and abundance of benthic macroinvertebrates (<250 microm) from sediments of eight reservoirs of the Paranapanema River (southeast Brazil), as well as from the main tributaries (Taquari, Pardo and Tibagi) and the mouth zone into the Paraná River were analyzed. Nineteen points distributed along 700 km were sampled quarterly (8 campaigns) during a ...

Cyanobacterial community patterns as water quality Bioindicators

 The main goal of this study was to examine the use of cyanobacteria for evaluating the quality of running water. Accordingly epilithic cyanobacterial communities were collected in Dez River and Ojeyreb drain in south of Iran. Samples were collected in two seasons: autumn and spring. Effective physical and chemical factors on the structure of cyanobacterial communities and the dispersi...
