In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

Simple Summary Phenotypic plasticity, the genome producing multiple phenotypes, is
central to an animal's ability to respond to environmental change, expected or otherwise. A …

Sexual reproduction requires coordinated contributions from both sexes to proceed
efficiently. However, the reproductive strategies that the sexes adopt often have the potential …

Sperm competition favors large, costly ejaculates, and theory predicts the evolution of
allocation strategies that enable males to plastically tailor ejaculate expenditure to sperm …

Males have finite resources to spend on reproduction. Thus, males rely on a 'time investment
strategy'to maximize their reproductive success. For example, male Drosophila …

The animal gut commonly contains a large reservoir of symbiotic microbes. Although these
microbes have obvious functions in digestion and immune defence, gut microbes can also …

It is increasingly clear that social environments have profound impacts on the life histories of
'non-social'animals. However, it is not yet well known how species with varying degrees of …

In polyandrous species, a male's reproductive success depends on his ability to fertilize
females, which, in turn, depends on his mating ability and his ability to produce competitive …

Sexual selection operates through consecutive episodes of selection that ultimately
contribute to the observed variance in reproductive success between individuals …

In a rapidly changing environment, does sexual selection on males elevate a population's
reproductive output? If so, does phenotypic plasticity enhance or diminish any such effect …
