Resumo: |
The objective of this study was to analyze the macroinvertebrate benthic communities in two small reservoirs, Monjolinho Reservoir and Fazzari Reservoir, both are localized in the campus of the Federal University of São Carlos, São Carlos city, São Paulo state, but they are on different anthropogenic disturbance. The samplings were carried out during the dry (April June) ant the wet (November December) seasons in 2004. In each dams the sampling were collected in 12 points random. At each site, three sampling units were taken with an Eckman-Birge sampler. Also were determinate more three sampling points at upstream in Monjolinho and Fazzari streams. Several physical and chemical variables were measured at each site and the means calculated to every season. Differents metrics were applied to compare the macroinvertebrate communities between the reservoirs. The analyses indicate that, overall, community persistent is correlated with the state environmental of each reservoir. The macroinvertebrate benthic community in Monjolinho reservoir was characterized by tolerant species dominant like Chironomus sp and Limnodrilus hoffmeisteri, they are very commons in trophic systems. In the other side in Fazzari reservoir, the no tolerant species (Chaoboridae and Campsurus sp) were dominants, this is an indication that the system is oligotrophic. |
