Migratory divides are contact zones between breeding populations that use divergent
migratory routes and have been described in a variety of species. These divides are of major …

… Table S3 summarises data on the temporal and spatial patterns of migration for the birds
tracked in this study and Delmore et al. (2012). On fall migration, birds with more inland alleles …

Details on the genetics of behavioral and quantitative phenotypes remain limited to a few
organisms. Such information is central to understanding both adaptation and speciation, as …

Adaptation to new environments often occurs in the face of gene flow. Under these
conditions, gene flow and recombination can impede adaptation by breaking down linkage …

Differential gene flow, reductions in diversity following linked selection and/or features of the
genome can structure patterns of genomic differentiation during the process of speciation. …

Detailed evaluations of genomic variation between sister species often reveal distinct
chromosomal regions of high relative differentiation (ie, “islands of differentiation” in F ST ), but …

Recent technological developments allow investigation of the repeatability of evolution at the
genomic level. Such investigation is particularly powerful when applied to a ring species, in …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Seasonal migration is a complex and variable behaviour with the potential to promote
reproductive isolation. In Eurasian blackcaps (Sylvia atricapilla), a migratory divide in central …

Heterogeneous patterns of genomic differentiation are commonly documented between closely
related populations and there is considerable interest in identifying factors that contribute …
