| spatial and temporal distribution of the zoobenthos community during the filling up period of porto primavera reservoir (paraná river, brazil). | this study is part of the limnological monitoring undertaken by the energy company of the state of são paulo (cesp) during the filling up process of the porto primavera reservoir (hydroelectric power plant engenheiro sérgio motta). this reservoir, located in the high paraná river between the states of são paulo and mato grosso do sul, is the fourth largest in the country. the first filling up phase started in december 1998 and the second phase in march 2001. samples for benthic community and sed ... | 2009 | 19347142 |
| 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 two-year period (2000 and 2001). the zoobenthos was characterized by a high species richness, (c.a. 100 ... | 2008 | 19197472 |
