A popular notion in sexual selection is that females are polyandrous and their offspring are
commonly sired by more than a single male. We now have large-scale evidence from …

Following Darwin's original insights regarding sexual selection, studies of intrasexual
competition have mainly focused on male competition for mates; by contrast, female …

Why do males and females frequently differ so markedly in body size and morphology? Sex,
Size, and Gender Roles is the first book to investigate the genetic, developmental, and …

Parents affect offspring fitness by propagule size and quality, selection of oviposition site,
quality of incubation, feeding of dependent young, and their defence against predators and …

Evolutionary biology has struggled to explain the coexistence of two basic observations:
Genetic variation is found in almost all traits in the presence of strong natural and sexual …

Why are females so choosy when it comes to mating? This question has puzzled and
marveled evolutionary and behavioral ecologists for decades. In mating systems in which …

In studies of population ecology, demography and life history evolution, among-individual
differences in traits associated with survival and reproduction are often attributed to variation …

Ecology Letters (2011) 14: 625–634 Abstract Condition is a nearly ubiquitous term in the
behavioural, physiological and evolutionary ecology literature; however, existing definitions …

The last decade has witnessed considerable theoretical and empirical investigation of how
male sexual ornaments evolve. This strong male-biased perspective has resulted in the …

The genic capture hypothesis offers a resolution to the question of how genetic variation in
male sexually selected traits is maintained in the face of strong female preferences. The …
