Behavioral interference between species, such as territorial aggression, courtship, and
mating, is widespread in animals. While aggressive and reproductive forms of interspecific …

Hybridization is not always limited to two species; often multiple species are interbreeding.
In birds, there are numerous examples of species that hybridize with multiple other species …

Host–symbiont relationships are ubiquitous in nature, yet evolutionary and ecological
processes that shape these intricate associations are often poorly understood. All orders of …

Christmas Island is located at the overlap of the Indian and Pacific Ocean marine provinces
and is a hot spot for marine hybridization. Here, we evaluate the ecological framework and …

Interspecific territoriality may play an important role in structuring ecological communities,
but the causes of this widespread form of interference competition remain poorly …

Much ecological and evolutionary theory predicts that interspecific interactions often drive
phenotypic diversification and that species phenotypes in turn influence species …

Adaptive radiations are characterized by the rapid proliferation of species. Explaining how
adaptive radiations occur therefore depends, in part, on identifying how populations become …

Understanding the origins and impacts of novel traits has been a perennial interest in many
realms of ecology and evolutionary biology. Here, we build on previous evolutionary and …

Hybridization is an important aspect of speciation, yet questions remain about the ecological
and environmental factors that influence hybridization among wild populations. We used …

Elucidating the relationship between genetic and cultural evolution is important in
understanding speciation, as learned premating barriers might be involved in maintaining …
