A comparison of genomic islands of differentiation across three young avian species pairsNARA Subscribed
Detailed evaluations of genomic variation between sister species often reveal distinct chromosomal regions of high relative differentiation (i.e., “islands of differentiation” in F ST ), but there is much debate regarding the causes of this pattern. We briefly review the prominent models of genomic islands of differentiation and compare patterns of genomic differentiation in three closely related pairs of New World warblers wi...
Ecology can inform genetics: Disassortative mating contributes to MHC polymorphism in Leach’s storm‐petrels ( Oceanodroma leucorhoa )NARA Subscribed
Studies of MHC‐based mate choice in wild populations often test hypotheses on species exhibiting female choice and male–male competition, which reflects the general prevalence of females as the choosy sex in natural systems. Here, we examined mutual mate‐choice patterns in a small burrow‐nesting seabird, the Leach’s storm‐petrel ( Oceanodroma leucorhoa ), using the major histocompatibility complex (MHC). The life history and e...
Recurrent selection explains parallel evolution of genomic regions of high relative but low absolute differentiation in a ring speciesNARA Subscribed
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 which spatial variation represents changes during the evolution of two species from one. We examined genomic variation among three subspecies of the greenish warbler ring species, using genotypes at 13 013 950 nucleotide sites along a new gr...
Genes of the major histocompatibility complex (MHC) have provided some of the clearest examples of how natural selection generates discordances between adaptive and neutral variation in natural populations. The type and intensity of selection as well as the strength of genetic drift are believed to be important in shaping the resulting pattern of MHC diversity. However, evaluating the relative contribution of multiple microevo...
Extensive polymorphism and geographical variation at a positively selected MHC class II B gene of the lesser kestrel ( Falco naumanni )NARA Subscribed
Understanding the selective forces that shape genetic variation in natural populations remains a high priority in evolutionary biology. Genes at the major histocompatibility complex (MHC) have become excellent models for the investigation of adaptive variation and natural selection because of their crucial role in fighting off pathogens. Here we present one of the first data sets examining patterns of MHC variation in wild pop...
