Abstract:The southern region of Brazil is rich in hydric and biogeographic resources, contributing to the formation of distinct ichthyofaunistic niches and facilitating the isolation of some species. Despite the great ecological importance, there are few cytogenetic and molecular studies on the ichthyofauna of these basins. Therefore, specimens of Ancistrus abilhoai and Hemiancistrus fuliginosus were analyzed by combining cytogenetic and mitochondrial markers. Cytogenetic analysis revealed a diploid number of 2n = 48 f… Show more
