It has been suggested that intrasexual competition can be a source of negative frequency‐
dependent selection, causing agonistic character displacement and facilitating speciation …

Background Assortative mating patterns for mate quality traits like body size are often
observed in nature. However, the underlying mechanisms that cause assortative mating …

Animal groups can show consistent behaviors or personalities just like solitary animals. We
studied the collective behavior of Temnothorax nylanderi ant colonies, including consistency …

African cichlid fishes not only exhibit remarkably high rates of speciation but also have some
of the fastest evolving sex determination systems in vertebrates. However, little is known …

Background It is hypothesized that one of the mechanisms promoting diversification in
cichlid fishes in the African Great Lakes has been the well-documented pattern of philopatry …

Populations experiencing localized mortality can recover in the short term by net movement
of individuals from adjacent areas, a process called compensatory immigration or spillover …

Cichlid fishes are the most species-rich group of all teleost fishes. Their diversity is centered
in the East African Great Lakes where more than 2,000 species evolved within the past 10 …

The mbuna are a speciose assemblage of small, colorful, primarily rocky shore cichlids
endemic to Lake Malawi. They have long been regarded as a group distinct from the lake's …

The active transmission of information from sender to receiver is a fundamental component
of communication, and is therefore a primary facet in evolutionary models of sexual …

Female mate preferences for male traits and resource characteristics affect trait evolution
and diversification. Here, we test the effects of male body traits and territory characteristics …
