Estado atual da sistemática dos peixes de água doce da América do Sul

Abstract: Resumo A fauna sul-americana de peixes de água doce, comparada com a do resto do mundo, é pouco conhecida. Há necessidade de coletas imediatas em muitas regiões, antes que os peixes se tornem raros ou se extingam. A fase descritiva da fauna de peixes de água doce da América do Sul desenvolveu-se em três períodos históricos. De 1750 até aproximadamente 1866, boa parte dos grandes exemplares de interesse comercial foi descrita por zoólogos europeus. De 1866 a 1930, caracterizou-se por descrições de espécies de g… Show more

“…2009). Although it is widely recognised that these natural barriers have produced distinct aquatic biotas above and below these barriers (e.g., Rahel 2007), we are still far from a complete understanding of their influence on freshwater fish assemblages, especially in tropical aquatic environments (Böhlke et al. 1978).…”

“…On the other hand, the suppression of natural barriers may result in habitat invasion by species so far isolated downstream of the barrier, as recently observed for Sete Quedas Falls in the Paraná River basin (Julio Junior et al 2009). Although it is widely recognised that these natural barriers have produced distinct aquatic biotas above and below these barriers (e.g., Rahel 2007), we are still far from a complete understanding of their influence on freshwater fish assemblages, especially in tropical aquatic environments (Böhlke et al 1978).…”

“…As in many groups of Neotropical freshwater fishes (Bohlke, Weitzman & Menezes, 1978), there are still many undescribed taxa within the Trichomycteridae. The situation in this family is, however, particularly acute in this regard, with literally enormous numbers of species still unknown to science, some of which are of great systematic interest.…”

“…De acordo com Reis, Kullander & Ferraris (2003), as Américas Central e do Sul abrigam 6.025 espécies de peixes de água doce (4.475 válidas e outras 1.550 a serem descritas). Por conta da enorme complexidade interespecífica, filogenética e zoogeográfica e da diversidade existente nas bacias hidrográficas brasileira, ainda há dúvidas sobre estimativas mais confiáveis do número de espécies e famílias das comunidades de peixes regionais (Bohlke, Weitzman & Menezes, 1978;Menezes, 1992).…”
