Última Effects of deforestation on headwater stream fish assemblages in the Upper Xingu River Basin, Southeastern Amazonia Neotropical Ichthyology Ilha,Paulo; Rosso,Sergio; Schiesari,Luis. ABSTRACT The expansion of the Amazonian agricultural frontier represents the most extensive land cover change in the world, detrimentally affecting stream ecosystems which collectively harbor the greatest diversity of freshwater fish on the planet. Our goal was to test the hypotheses that deforestation affects the abundance, richness, and taxonomic structure of headwater stream fish assemblages in the Upper Xingu River Basin, in Southeastern Amazonia. Standardized sampling surveys in replicated first order streams demonstrated that deforestation strongly influences fish assemblage structure. Deforested stream reaches had twice the fish abundance than reference stream reaches in primary forests. These differences in assemblage structure were largely driven...

Benthic macroinfauna of six beaches near to Guaratuba Bay, Paraná, Brazil were studied in summer and winter of 1994. Sampling stations were distributed along a transect, from upper of the drift line to depths of nearly 3 m behind the first break of the surf zone. Biological and sedimentological samples, slope, wave height and period were recorded. Subtidal samples were collected by scuba diving. The beaches varied from extremely inclined, composed of coarse sediments, to low inclined, composed of fine and very fine sands. The polychaete Scolelepis squamata, was the numerically dominant species in those beaches composed by fine to very fine sand in the subaereal profile. The echinoderm Mellita quinquiesperforata occurred in the last stations of the surf...
