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 …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

Assortative mating occurs when there is a correlation (positive or negative) between male
and female phenotypes or genotypes across mated pairs. To determine the typical strength …

Biological invasions dramatically affect the distribution, abundance and reproduction of
many native species. Because of these ecological effects, exotic species can also influence …

Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

Population Genetics and Microevolutionary Theory Explore the fundamentals of the
biological implications of population genetic theory In the newly revised Second Edition of …

Divergent natural selection has been shown to promote speciation in a wide range of taxa.
For example, adaptation to different ecological environments, via divergent selection, can …

Food webs in agricultural systems are complex and trophic linkages are difficult to track
using conventional methodologies. Here, we review three alternative approaches that allow …

Pheromone-based behaviours are crucial in animals from insects to mammals,, and
reproductive isolation is often based on pheromone differences,,,. However, the genetic …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …
