Abstract

The study of composition and trophic organization of the ichthyofauna in streams with different levels of anthropogenic impact is an important tool to assess the integrity of these water bodies, providing a consistent approach to understand the interactive processes within aquatic communities. Long term studies of disturbed environments are fundamental to evaluate not only the continuous effects of anthropogenic action, but also the seasonal modifications that are common in small and physically fragile streams. Thus, the analysis of stream community structure in different spatial and temporal scales is important to the development of biological monitoring programs and species conservation by allowing the distinction between natural variability and that caused by environments changes. The ichthyofauna of three tributaries of Santo Inácio River (Bofete, SP), located on a sand mining area, will be studied in order to analyze spatial and temporal variation in the species composition and in the species food partitioning. The environmental features, the composition and diet of the ichthyofauna will be analyzed in July/2013 and January/2014, representing a dry and wet season, respectively. These data will be compared with studies performed in 2001/2002 in the same area to verify possible changes in the ichthyofauna structure in face of possible environmental changes over this time period.
