The characiform fishes of the Neotropics and Africa radiated remarkably in ecomorphology,
but the macroevolutionary processes responsible for their biodiversity remain unexplored …

Understanding why some clades diversify greatly while others do not is a major goal of
evolutionary biology. Both abiotic and biotic factors are important in driving unequal …

O trato digestório de 44 exemplares de Schizodon knerii foi estudado utilizando técnicas
anatômicas, histológicas e histoquímicas. Boca tem posição terminal, epitélio labial é …

Convergent evolution is often interpreted as evidence of natural selection favoring an
optimal phenotype during adaptation. Morphological convergence is frequently found …

We tested the contribution of the phylogenetic and specific components to the
ecomorphological structure of stream fish from the upper Paraguai River and upper São …

Astyanax mexicanus offers a unique model for studying parallel evolution, with cave-
dwelling forms arising from at least two distinct surface lineages. Here, we examined …

We report the first draft genome assembly for Prochilodus magdalenae, the leading
representative species of the Prochilodontidae family in Colombia. This 1.2-Gb assembly …

Twenty polymorphic microsatellite markers were developed for the Neotropical fish
Leporinus obtusidens using a next generation sequencing approach and tested in two other …

The order Characiformes is one of the most diverse and widely distributed groups of fishes
in cis-Andean basins. That diversity is reflected in the São Francisco River (Brazil), where …

Differences in food intake and morphological attributes may facilitate the coexistence of
detritivorous fish. The present study investigated the possible differences in the feeding …
