An international team of researchers is challenging a commonly held view that explains how so many species of birds came to inhabit the Neotropics, an area rich in rain forest that extends from Mexico ...

New research has uncovered how different populations of the bird crimson rosella are related to each other -- a discovery which has important implications for research into how climate change may ...

New research challenges a commonly held view that explains how so many species of birds came to inhabit the Neotropics, an area rich in rain forest that extends from Mexico to the southernmost tip of ...

Introduction: Studying birds in time and space / Dieter Thomas Tietze -- Integrative taxonomy of birds : the nature and delimitation of species / George Sangster -- Studying speciation : genomic ...

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 phylogenetic ...

A University of Chicago biologist and world-renowned expert on bird speciation has compiled eight years of research and writing into a recently published book, Speciation in Birds. Trevor Price, ...

How long does it take for a new species to develop? Not long, it turns out. In fact, only a few thousand years — an evolutionary blink of an eye. A recent article published in Nature tracked ...

A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological ...

Using the world’s first family tree linking every known bird species, scientists, including two at Simon Fraser University, have discovered that birds appear to be accelerating their rate of evolution ...

We tested for the evolutionary relationship between stress response, speciation rate, and subspecies richness in birds by relying on the HormoneBase repository, from which we calculated within- and ...
