The metaphor of 'genomic islands of speciation'was first used to describe heterogeneous
differentiation among loci between the genomes of closely related species. The biological …

Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Species can be defined as populations that are diagnosably distinct, reproductively isolated,
cohesive, or exclusive groups of organisms. Boundaries between species in sympatry are …

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 …

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 …

Recently diverged taxa may continue to exchange genes. A number of models of speciation
with gene flow propose that the frequency of gene exchange will be lower in genomic …

Hybrid zones provide a powerful opportunity to analyze ecological and evolutionary
interactions between divergent lineages. As such, research on hybrid zones has played a …

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

Rapid and inexpensive methods for genomewide single nucleotide polymorphism (SNP)
discovery and genotyping are urgently needed for population management and …

Natural hybridization between closely related taxa is a common phenomenon in both plants
and animals. Hybridization has often been viewed as a destructive force that could erode …
