The vast mammal diversity of the Neotropics is the result of a long evolutionary history.
During most of the Cenozoic, South America was an island continent with an endemic …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

The biotic and geologic dynamics of the Great American Biotic Interchange are reviewed
and revised. Information on the Marine Isotope Stage chronology, sea level changes as well …

The remarkable radiation of South American (SA) canids produced 10 extant species
distributed across diverse habitats, including disparate forms such as the short-legged …

Comparative biologists often attempt to draw inferences about tempo and mode in evolution
by comparing the fit of evolutionary models to phylogenetic comparative data consisting of a …

Background Adaptive radiation, the evolution of ecological and phenotypic diversity from a
common ancestor, is a central concept in evolutionary biology and characterizes the …

Background Despite being one of the most studied families within the Carnivora, the
phylogenetic relationships among the members of the bear family (Ursidae) have long …

The mammalian order Carnivora has attracted the attention of scientists of various
disciplines for decades, leading to intense interest in defining its supra-familial relationships …

We analyzed a concatenated (8492bp) nuclear–mitochondrial DNA data set from 44
musteloids (including the first genetic data for Lyncodon patagonicus) with parsimony …

Adaptive radiation is hypothesized to be a primary mechanism that drives the remarkable
species diversity and morphological disparity across the Tree of Life. Tests for adaptive …
