Species range limits involve many aspects of evolution and ecology, from species
distribution and abundance to the evolution of niches. Theory suggests myriad processes by …

Recent theory and empirical evidence have provided new insights regarding how
evolutionary forces interact to shape adaptation at stable and transient range margins …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Today's scientists are facing the enormous challenge of predicting how climate change will
affect species distributions and species assemblages. To do so, ecologists are widely using …

Speciation generally involves a three-step process—range expansion, range fragmentation
and the development of reproductive isolation between spatially separated populations …

Accurate forecasts of biological invasions are crucial for managing invasion risk but are
hampered by niche shifts resulting from evolved environmental tolerances (fundamental …

Radiations of ecologically and morphologically differentiated sympatric species can exhibit
the pattern of a burst of diversification, which might be produced by ecological divergence …

What stops populations expanding into new territory beyond the edge of a range margin?
Recent models addressing this problem have brought together population genetics and …

Although sexual interactions between species (reproductive interference) have been
reported from a wide range of animal taxa, their potential for determining species …

Character displacement is the process by which traits evolve in response to selection to
lessen resource competition or reproductive interactions between species. Although …
