Sexual selection is a key component of evolutionary biology. However, from the very
formulation of sexual selection by Darwin, the nature and extent of sexual selection have …

Theory suggests that male fitness generally increases steadily with mating rate, while one or
a few matings are sufficient for females to maximize their reproductive success. Contrary to …

A growing body of evidence has begun to reveal flaws in the traditional assumption of
female passivity and lack of discrimination after copulation has begun. William Eberhard has …

The past decade has seen a profound change in the scientific understanding of
reproduction. The traditional view of reproduction as a joint venture undertaken by two …

One hundred years after Darwin considered how sexual selection shapes the behavioral
and morphological characteristics of males for acquiring mates, Parker realized that sexual …

▪ Abstract We describe the impact of recent life-history plasticity theory on insect studies,
particularly on the interface between genetics and plasticity. We focus on the three …

Nuptial feeding encompasses any form of nutrient transfer from the male to the female
during or directly after courtship and/or copulation. In insects, nuptial gifts may take the form …

During copulation, male redback spiders (Latrodectus hasselti: Theridiidae) position
themselves above the female's jaws. This apparent male complicity in sexual cannibalism is …

Explanations for rapid species' range expansions have typically been purely ecological, with
little attention given to evolutionary processes. We tested predictions for the evolution of …

Edible and seminal gifts that male arthropods transfer to their mates range from important
material donations to items that provide little direct benefit. Recent reviews and research …
