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 …

What explains variation in the strength of sexual selection across species, populations or
differences between the sexes? Here, we show that unifying two well‐known lines of …

A focus on novel, confirmatory, and statistically significant results leads to substantial bias in
the scientific literature. One type of bias, known as “p-hacking,” occurs when researchers …

There are substantial concerns that increasing levels of anthropogenic noise in the oceans
may impact aquatic animals. Noise can affect animals physically, physiologically and …

Mate availability has been shown to influence intrasexual competition and mate-guarding
behavior across a variety of species. Nevertheless, little is known about how perceived mate …

Resources are often central to the formation and persistence of human consortships, and to
the evolutionary fitness consequences of those consortships. As a result, the distribution of …

The current investigation examined whether women's perceptions of the sex ratio (ratio of
women to men) in the local population influence their body dissatisfaction and weight loss …

Two studies examined the connection between women's sexual orientation, their
sociosexuality (ie willingness, attitudes, and desires associated with uncommitted sexual …

The operational sex ratio (OSR) and density are considered important factors affecting the
strength of sexual selection. Although there is increasing evidence that OSR and density …

Our understanding of sexual selection has greatly improved during the last decades. The
focus is no longer solely on males, but also on how female competition and male mate …
