The fitness of hybrids is a critical determinant of gene flow between hybridizing populations.
If hybrid phenotypes change predictably as parental populations become increasingly …

Hybrid incompatibilities occur when interactions between opposite-ancestry alleles at
different loci reduce the fitness of hybrids. Most work on incompatibilities has focused on …

Determining the underlying causes for the links between form, function, and the
environment, and how these correlations relate to adaptation to novel environments …

Hybridization is the process of interbreeding between distinct genomic lineages.
Environmental disturbances have been associated with increased hybridization between …

In contrast to ecological speciation, where reproductive isolation evolves as a consequence
of divergent natural selection, speciation by parallel natural selection has been less …

Selection against mismatched traits in hybrids is the phenotypic analogue of intrinsic hybrid
incompatibilities. Mismatch occurs when hybrids resemble one parent population for some …

Threespine stickleback fish (Gasterosteus aculeatus) have long been an ecological and
evolutionary model system. Stickleback exhibit remarkable patterns of parallel adaptation …

Differences in ecological factors between habitats drive evolutionary divergence and can
lead to the generation of new species. While many studies provide evidence suggesting a …

Despite deep evolutionary conservation, recombination rates vary greatly across the
genome and among individuals, sexes and populations. Yet the impact of this variation on …
