Cryptic female choice (CFC) represents postmating intersexual selection arising from female-
driven mechanisms at or after mating that bias sperm use and impact male paternity share …

Heatwaves are occurring at an increasing frequency and intensity under ongoing climate
change. As many reproductive traits—including mating behaviour and gamete traits—are …

While both sperm number and quality are now recognized to be important in determining the
outcome of sperm competition, very few studies have experimentally assessed the influence …

As inbreeding is costly, it has been suggested that polyandry may evolve as a means to
reduce the negative fitness consequences of mating with genetically related males. While …

Strategic ejaculate adjustments occur when males modify their investment in sperm and
nonsperm components of the ejaculate according to the context. This strategy is expected to …

Pharmaceutical pollutants constitute a major threat to wildlife because of their capacity to
induce biological effects at low doses. One such pollutant is the antidepressant fluoxetine …

Deleterious mutations can accumulate in the germline with age, decreasing the genetic
quality of sperm and imposing a cost on female fitness. If these mutations also affect sperm …

The vertebrate brain is a remarkably plastic organ, which responds quickly to environmental
changes. However, to date, studies investigating plasticity in brain morphology have focused …

Recent studies suggest that environmentally induced effects on sperm phenotype can
influence offspring phenotype beyond the classic Mendelian inheritance mechanism …

Recent theory predicts that in species where females tend to mate with the relatively most
ornamented males, males may increase their attractiveness to females, and hence mating …
