Characterizing the population history of a species and identifying loci underlying local
adaptation is crucial in functional ecology, evolutionary biology, conservation and …

Abstract With almost 2,600 species, Rodentia is the most diverse order of mammals. Here,
we provide an overview of changes in our understanding of the systematics of living rodents …

The Mediterranean basin is a hotspot of biodiversity, fuelled by climatic oscillation and
geological change over the past 20 million years. Wall lizards of the genus Podarcis are …

Background Although hybridization is thought to be relatively rare in animals, the raw
genetic material introduced via introgression may play an important role in fueling …

Admixture is recognized as a widespread feature of human populations, renewing interest in
the possibility that genetic exchange can facilitate adaptations to new environments. Studies …

Theories of how species evolve in changing environments mostly consider single species in
isolation or pairs of interacting species. Yet all organisms live in diverse communities …

Adaptive introgression can provide novel genetic variation to fuel rapid evolutionary
responses, though it may be counterbalanced by potential for detrimental disruption of the …

Studies on polymorphisms have been foundational to our understanding of evolution. The
presence of different phenotypic morphs is sometimes considered a precursor to speciation …

Mutations of small effect underlie most adaptation to new environments, but beneficial
variants with large fitness effects are expected to contribute under certain conditions. Genes …

While it is appreciated that population size changes can impact patterns of deleterious
variation in natural populations, less attention has been paid to how gene flow affects and is …
