A multimetric index based on fish fauna for the evaluation of the biotic integrity of streams at a mesohabitat scale Índice multimétrico com base na fauna de peixes para avaliação da integridade biótica de riachos em escala de meso-hábitat

AIM: In this study, we evaluated the ability of the Index of Biotic Integrity (IBI), based on fish fauna, to discriminate between reference streams and degraded streams at a mesohabitat scale. METHODS: We sampled the ichthyofauna of 96 mesohabitats (runs, riffles and pools) with electrofishing gear...
