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

ABSTRACT A central paradigm in evolutionary biology is that the fundamental divergence in
the fitness interests of the sexes ('sexual conflict') can lead to both the evolution of sex …

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 …

Sexual conflict occurs whenever there is sexually antagonistic selection on shared traits.
When shared traits result from interactions (eg, mating rate) and have a different genetic …

Aggressive behaviours are among the most striking displayed by animals, and aggression
strongly impacts fitness in many species. Aggression varies plastically in response to the …

In haplodiploids, females pass their genes on to all their offspring, whereas a male's genes
are only passed on to his daughters [1]. Hence, males always benefit from female-biased …

Stronger condition-dependence in sexually selected traits is well-documented, but how this
relationship is established remains unknown. Moreover, resource availability can shape …

A handful of studies have investigated sexually antagonistic constraints on achieving sex-
specific fitness optima, although exclusively through male-genome-limited evolution …

Highlights•We studied laboratory-adapted populations of Drosophila melanogaster fruit
flies.•Males can perceive future risk of competition by the number of rivals around.•Males …

Biodiversity is increasingly threatened by unpredictable, frequent, and intense climatic
events like heatwaves that pose harmful impacts on ectotherms. Beyond the health and …
