Hybridization among diverging lineages is common in nature. Genomic data provide a
special opportunity to characterize the history of hybridization and the genetic basis of …

Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Under climate change, species unable to track their niche via range shifts are largely reliant
on genetic variation to adapt and persist. Genomic vulnerability predictions are used to …

Speciation results from the progressive accumulation of mutations that decrease the
probability of mating between parental populations or reduce the fitness of hybrids—the so …

This third edition of Reconstructing Quaternary Environments has been completely revised
and updated to provide a new account of the history and scale of environmental changes …

Density-dependent processes play a key role in the spatial structuring of biodiversity.
Specifically, interrelated demographic processes, such as gene surfing, high-density …

Species‐level taxonomy derives from empirical sources (data and techniques) that assess
the existence of spatiotemporal evolutionary lineages via various species “concepts.” These …

Defining the impacts of anthropogenic climate change on biodiversity and species
distributions is currently a high priority. Niche models focus primarily on predicted changes …

Hybrid zones have been promoted as windows on the evolutionary process and as
laboratories for studying divergence and speciation. Patterns of divergence between …

Allopatric speciation requiring an unbroken period of geographical isolation has been the
standard model of neo-Darwinism. While doubts have been repeatedly raised, strict …
