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 …

The genus Gambusia represents approximately 45 species of polyandrous livebearing
fishes with reversed sexual size dimorphism (ie males smaller than females) and with …

Sex ratio and sexual dimorphism have long been of interest in population and evolutionary
ecology, but consequences for communities and ecosystems remain untested. Sex ratio …

Invasive species that rapidly spread throughout novel distribution ranges are prime models
to investigate climate-driven phenotypic diversification on a contemporary scale. Previous …

Males and females have divergent reproductive interests arising from their unequal
investments in offspring. This sexual conflict drives an antagonistic arms race that influences …

Metagenomics and bacterial culture were used to determine the normal skin microbiome of
the Western mosquitofish (Gambusia affinis). This is the first study of G. affinis, and the most …

We review the behavioral and physiological ecology of rubyspot damselflies before, during,
and after copulation. Adult rubyspots are sexually dimorphic, with males bearing a red wing …

Success of animal translocations depends on improving postrelease demographic rates
toward establishment and subsequent growth of released populations. Short‐term metrics …

Most studies of parasite-mediated sexual selection target organisms where female or male
mate choice is the major driving force of sexual selection, leaving the effects of parasites on …

In populations with a male-biased operational sex ratio, coercive mating by males can have
fitness consequences for females. One component of reduced fitness for females in …
