Landscape‐scale population genetic structure in vagile vertebrates was commonly
considered to be a contradiction in terms whereas recent studies have demonstrated …

Understanding the mechanisms driving the extraordinary diversification of parasites is a
major challenge in evolutionary biology. Co-speciation, one proposed mechanism that could …

Background Genes at the major histocompatibility complex (MHC) are known for high levels
of polymorphism maintained by balancing selection. In small or bottlenecked populations …

Abstract Swainson's Hawks (Buteo swainsoni) are large raptors with a breeding distribution
extending across much of western North America where they were historically considered …

Population range expansions and contractions as a response to climate and habitat change
throughout the Quaternary are known to have contributed to complex phylogenetic and …

Background Phenotypic and molecular genetic data often provide conflicting patterns of
intraspecific relationships confounding phylogenetic inference, particularly among birds …

Many island avian populations are of conservation interest because they have a higher risk
of extinction than mainland populations. Susceptibility of island birds to extinction is primarily …

Traditional subspecies classifications may suggest phylogenetic relationships that are
discordant with evolutionary history and mislead evolutionary inference. To more accurately …

Migratory species are of increased conservation concern because of their reliance on
multiple, geographically disjunct habitats. An understanding of how long-term ecological …

Patterns of social organization and mating systems have been shown to be functions of
ecological factors such as resource allocation and breeding density. In some species …
