Molecular Phylogeny and Biogeographic History of the Armored Neotropical Catfish Subfamilies Hypoptopomatinae, Neoplecostominae and Otothyrinae (Siluriformes: Loricariidae)

A strong influence of river capture is infer in the accumulation of modern clade species-richness values, the formation of the modern basin-wide species assemblages, and the presence of many low-diversity, early-branching lineages restricted to the Atlantic Coastal Drainages.

Genetic structure and historical diversification of catfish Brachyplatystoma platynemum (Siluriformes: Pimelodidae) in the Amazon basin with implications for its conservation

The results show high levels of haplotype diversity and point to the occurrence of two structured populations of B. platynemum in the Amazon basin with high values for FST, as well as of differences in water chemistry in Madeira River.

Transcontinental dispersal, ecological opportunity and origins of an adaptive radiation in the Neotropical catfish genus Hypostomus (Siluriformes: Loricariidae)

The geographical remoteness of the Paraná River basin, its recent history of marine incursion, and its continuing exclusion of many species that are widespread in other tropical South American rivers suggest that ecological opportunity played an important role in facilitating the observed accelerations in diversification.

Accelerated Diversification Explains the Exceptional Species Richness of Tropical Characoid Fishes.

Three species-rich and ecomorphologically diverse lineages that originated more than 60 Ma in the Paleocene experienced particularly notable bursts of Oligocene diversification and now account collectively for 68% of the approximately 2,150 species of Characoidei.

A new map of the tiger shark ( Galeocerdo cuvier ) genetic population structure in the western Atlantic Ocean: Hypothesis of an equatorial convergence centre

The tiger shark (Galeocerdo cuvier) is a common widespread coastal–pelagic shark species whose population genetic structure has only recently been the object of genetic studies. In this study, the…
