Název v původním jazyce

Molecular phylogeny and biogeography of the Neotropical cichlid fish tribe Cichlasomatini (Teleostei: Cichlidae: Cichlasomatinae)

Popis výsledku v původním jazyce

We have conducted the first comprehensive molecular phylogeny of the tribe Cichlasomatini including all valid genera as well as important species of questionable generic status. We analyzed sequences from 2 mitochondrial (16S rRNA, cytochrome b) and onenuclear marker (first intron of S7 ribosomal gene) totalling 2236 bp. Our data suggest that all genera except Aequidens are monophyletic, but we found important disagreements between the traditional morphological relationships and the phylogeny based onour molecular data. Estimation of divergence times suggests that the divergence of Cichlasomatini started around 44 Mya with the vicariance between coastal rivers of the Guyanas and remaining cis-andean South America, followed by evolution of the inner groups, one clade in Western Amazon, and the second clade in the Eastern Amazon. Vicariant divergence has played importantly in evolution of cichlasomatine genera, with dispersal limited to later range extension of species within genera.
