An implicit assumption of speciation biology is that population differentiation is an important
stage of evolutionary diversification, but its significance as a rate-limiting control on …

A fundamental need in conserving species and their habitats is defining distinct entities that
range from individuals to species to ecosystems and beyond (Table; Ryder …

The family Vireonidae represents one of the most widespread and well-known New World
avian radiations, but a robust species-level phylogeny of the group is lacking. Here, we infer …

Anthropogenic alterations in the natural environment can be a potent evolutionary force. For
species that have specific habitat requirements, habitat loss can result in substantial genetic …

We used multilocus phylogeographic analyses, morphometric measurements, and
environmental niche models (ENMs) to analyze the recent evolution of the golden vireo …

A thorough understanding of the effects of spatially and temporally variable demographic
drivers of population processes is necessary to accurately evaluate potential source-sink …

The effect of separation by biogeographic features followed by secondary contact can blur
taxonomic boundaries and produce complex genetic signatures. We analyzed population …

Nest predation and brood parasitism likely cause declines in many songbird species, yet the
rate of these declines varies among species. Simultaneously studying co-occurring species …

The Orinoco Crocodile (Crocodylus intermedius) is a critically endangered crocodile species
found only in the Orinoco River basin in Colombia and Venezuela, in northwestern South …

Understanding the interplay of dispersal and how it translates into gene flow is key to
understanding population processes, and especially so for endangered species occupying …
