“…For example, a recent review of Pseudoplatystoma using morphological characters showed that the widely distributed species P. fasciatum actually represents a complex of five species, one in each hydrographic basin that they occupy [44]. Another survey of different populations of Gymnotus pantherinus from southeast Brazil showed that each population was genetically distinct with few shared and many exclusive haplotypes [45]. The authors suggested that the development of geographic barriers resulting from the formation of the Serra do Mar, resulted in a pattern of allopatric speciation [45].…”

The authors suggested that the development of geographic barriers resulting from the formation of the Serra do Mar, resulted in a pattern of allopatric speciation [45]. Two surveys analyzing Piabina argentea from the Upper Paraná and São Francisco River basins with molecular and cytogenetic tools showed that the nominal species comprises a species complex with six distinct putative species [18,19].…”

“…Conclui-se que a complexidade das linhagens de T. torquatus encontradas não podem ser explicadas somente com uma ou outra teoria, como a dos refúgios ou dos rios. Na verdade, na Mata Atlântica, áreas compreendidas entre os principais rios são congruentes com as áreas preditas como remanescentes florestais do Pleistoceno, logo, torna-se difícil distinguir entre tais hipóteses alternativas (Baroni, 2010). Essa ausência de um padrão geral pode demonstrar uma história evolutiva complexa devido a influência diferencial de eventos paleogeográficos e paleoclimáticos na diferenciação dos grupos taxonômicos (Cracraft & Prum, 1988).…”
