Condition-specific competition is widespread in nature. Species inhabiting heterogeneous
environments tend to differ in competitive abilities depending on environmental stressors …

A major goal of modern evolutionary biology is to understand the causes and consequences
of phenotypic plasticity, the ability of a single genotype to produce multiple phenotypes in …

An animal's susceptibility to risk may be partly dependent on its body size. But are larger
individuals bolder? We assessed this question by measuring time to emerge from a shelter …

Males using alternative male mating tactics (AMTs) may express their mating effort in a
variety of ways. In polygynous species with limited sexual dimorphism, differences in male …

Male alternative reproductive strategies are found in some species of most major animal
taxa but are especially widespread in fishes. Mature males of the shortfin molly, Poecilia …

Exaggerated male traits under sexual selection are often used for both competition and
courtship, raising the question of whether ornaments evolved simultaneously for both …

Sex differences in personality traits, such as boldness, are often driven by differences in life
history strategies. Specifically, in a polygynous mating system where males defend …

Male sexually selected signals can indicate competitive ability by honestly signaling fitness-
relevant traits such as condition or performance. However, behavior can also influence …

Compared to many types of phenotypic plasticity, developmental plasticity of mating
behaviour in response to the social environment has received less attention. Understanding …

The persistence of gynogenetic organisms is an evolutionary paradox. An ideal system for
examining the persistence of gynogens is the unisexual–bisexual mating complex of the …
