Sexual selection has the potential to decrease mean fitness in a population through an array
of costs to nonsexual fitness. These costs may be offset when sexual selection favors …

Mutational input is the ultimate source of genetic variation, but mutations are not thought to
affect the direction of adaptive evolution. Recently, critics of standard evolutionary theory …

The evolution of male traits that inflict direct harm on females during mating interactions can
result in a so-called tragedy of the commons, where selfish male strategies depress …

The maintenance of genetic variance in fitness represents one of the most longstanding
enigmas in evolutionary biology. Sexually antagonistic (SA) selection may contribute …

Earth's biodiversity is undergoing mass extinction due to anthropogenic compounding of
environmental, demographic and genetic stresses. These different stresses can trap …

Females and males carry nearly identical genomes, which can constrain the evolution of
sexual dimorphism and generate conditions that are favourable for maintaining sexually …

Heatwaves are increasing in frequency and intensity due to climate change, pushing
animals beyond physiological limits. While most studies focus on survival limits, sublethal …

Competition for mates can be a major source of selection, not just on secondary sexual traits
but across the genome. Mate competition strengthens selection on males via sexual …

To mitigate the effects of climate change, it is important to understand species' responses to
increasing temperatures. This has often been done by studying survival or activity at …

Abstract Theory predicts that the ability of selection and recombination to purge mutation
load is enhanced if selection against deleterious genetic variants operates more strongly in …
