Abstract

This study describes the composition and distribution of fish species in an Atlantic Forest Environmental Protection Area located in the city of São Paulo (APA Capivari-Monos), with the aim of determining the composition, distribution and the relationship of the community to local environmental conditions. Three main rivers (Capivari, Taquacetuba and Embu-Guaçu) were sampled by electrofishing at a total of 10 sites. Twenty-five species were recorded, of which 20% (Characidium oiticicai, Pseudocorynopoma heterandria, Pseudotocinclus tietensis Trichomycterus paolence and Glandulocauda melanopleura) are considered endangered for the State of São Paulo. Community attributes varied between rivers and along the longitudinal axis, indicating that several species have a restricted distribution and specific ecological requirements.

Este estudo descreve a composição e distribuição de espécies de peixes em uma Área de Proteção Ambiental de Mata Atlântica localizada na cidade de São Paulo (APA Capivari-Monos), com o objetivo de determinar a composição, distribuição e a relação da comunidade com características ambientais. Três rios principais (Capivari, Taquacetuba e Embu-Guaçu) foram amostrados com pesca elétrica em um total de dez pontos de coleta. Vinte e cinco espécies foram registradas, das quais 20% (Characidium oiticicai, Pseudocorynopoma heterandria, Pseudotocinclus tietensis, Trichomycterus paolence e Glandulocauda melanopleura) são consideradas ameaçadas para o Estado de São Paulo. Os atributos da comunidade variaram entre os rios e ao longo do eixo longitudinal, indicando que diversas espécies apresentam uma distribuição restrita e exigências ecológicas específicas.
