For sexual selection to act on a given sex, there must exist variation in the reproductive
success of that sex as a result of differential access to mates or fertilisations. The …

The year 2021 marks the 150th anniversary of the publication of Charles Darwin's
extraordinary book The Descent of Man and Selection in Relation to Sex. Here, we review …

Over the last decades, the field of sexual selection underwent a paradigm shift from sexual-
stereotype thinking of “eager” males and “coy” females towards a more nuanced perspective …

Sexual selection has long been acknowledged as an important evolutionary force, capable
of shaping phenotypes ranging from fascinating and unusual displays to cryptic traits whose …

Human marriage systems, characterized by long-term partnerships and extended windows
of parental care, differ from the mating systems of pulsed or seasonally breeding non-human …

Competition for mate acquisition is the hallmark of any sexual organism. In insect-pollinated
plants, competition to attract pollinators is expected to result in pollinator-mediated selection …

In a rapidly changing environment, does sexual selection on males elevate a population's
reproductive output? If so, does phenotypic plasticity enhance or diminish any such effect …

In anisogamous species, sexual selection is expected to be stronger in males. Bateman's
principles state that the variance in (i) reproductive and (ii) mating success is greater for …

Abstract In 1948, Angus Bateman presented experiments and concepts that remain
influential and debated in sexual selection. The Bateman gradient relates reproductive …

The consequences of natural selection can be understood from a purely statistical
perspective. In contrast, an explicitly causal approach is required to understand why trait …
