Aposematic theory has historically predicted that predators should select for warning signals
to converge on a single form, as a result of frequency‐dependent learning. However …

Polymorphic species, in which multiple variants coexist within a population, are often used
as model systems in evolutionary biology. Recent research has been dominated by the …

Genetic variation in female resistance and tolerance to male mating harassment can affect
the outcome of sexually antagonistic mating interactions. We investigated female mating …

Negative frequency-dependent selection (NFDS) is one of the most powerful selective forces
maintaining genetic polymorphisms in nature. Recently many prospective cases of …

Studies of heritable colour polymorphisms allow investigators to track the genetic dynamics
of natural populations. By comparing polymorphic populations over large geographic areas …

Background Establishment of geographic morph frequency clines is difficult to explain in
organisms with limited gene flow. Balancing selection, such as negative frequency …

Sexual selection, more so than natural selection, is posited as the major cause of sex
differences. Here I show ecological correlations between solar radiation levels and sexual …

Disentangling the relative importance and potential interactions of selection and genetic drift
in driving phenotypic divergence of species is a classical research topic in population …

Color polymorphism in natural populations can manifest as a striking patchwork of
phenotypes in space, with neighboring populations characterized by dramatic differences in …

Background Studying contemporary hybridization increases our understanding of
introgression, adaptation and, ultimately, speciation. The sister species Ischnura elegans …
