Data from: Spatially explicit models of divergence and genome hitchhiking

Samuel M. Flaxman, Jeffrey L. Feder, Patrik Nosil, J. L. Feder, S. M. Flaxman & P. Nosil
Strong barriers to genetic exchange can exist at divergently selected loci, whereas alleles at neutral loci flow more readily between populations, thus impeding divergence and speciation in the face of gene flow. However, ‘divergence hitchhiking’ theory posits that divergent selection can generate large regions of differentiation around selected loci. ‘Genome hitchhiking’ theory suggests that selection can also cause reductions in average genome-wide rates of gene flow, resulting in widespread genomic divergence (rather than divergence only...

Data from: Cast adrift on an island: introduced populations experience an altered balance between selection and drift

A long-standing question in evolutionary biology is what becomes of adaptive traits when a species expands its range into novel environments. Here we report the results of a study on an adaptive colour pattern polymorphism (stripes) of the coqui frog following its introduction to Hawaii from Puerto Rico. We compared population differentiation (φ'ST and FST) for the stripes locus —which underlies this colour pattern polymorphism— with neutral microsatellite loci to test for a signature of...
