Since the first investigation 25 years ago, the application of genetic tools to address
ecological and evolutionary questions in elasmobranch studies has greatly expanded. Major …

Islands have long provided material and inspiration for the study of evolution and ecology.
The West Indies are complex historically and geographically, providing a rich backdrop for …

Evolutionary theory has gained tremendous insight from studies of adaptive radiations. High
rates of speciation, morphological divergence, and hybridization, combined with low …

Molecular clocks are widely used to date phylogenetic events, yet evidence supporting the
rate constancy of molecular clocks through time and across taxonomic lineages is weak …

Abstract Late Pliocene and Pleistocene climatic instability has been invoked to explain the
buildup of Neotropical biodiversity, although other theories date Neotropical diversification …

Many evolutionary studies of birds rely on the estimation of molecular divergence times and
substitution rates. In order to perform such analyses, it is necessary to incorporate some form …

Background During the last ten years, major advances have been made in characterizing
and understanding the evolution of mitochondrial DNA, the most popular marker of …

Discussions aimed at resolution of the Tree of Life are most often focused on the
interrelationships of major organismal lineages. In this study, we focus on the resolution of …

The Andean uplift played important roles in the historical diversification of Neotropical
organisms, both by producing new high-elevation habitats that could be colonized and by …

We investigated the degree of geographical shifts of transmission areas of vector‐borne
avian blood parasites (Plasmodium, Haemoproteus and Leucocytozoon) over ecological …
