Concepts

Explains how acoustic signal structure is shaped by habitat-driven selection that enhances the propagation of relatively undegraded vocalizations

An individual locus shows strong adaptive fitness effects in one habitat, but little or no cost in other habitats

Males infected with parasites will have reduced mate attraction as a consequence of less enhanced secondary sexual characters due to energy allocation to immune response

The degree to which novel resources resemble historical resources in their chemical or physical cues

Species with larger ecological breadth have greater phenotypic variation due to exposure to diverse environmental conditions

Alternate alleles are favoured in distinct habitats, and polymorphism is maintained by selection

plants invest moderately in attracting pollinators early in season and creating flowers to hedge bets on abiotic resource conditions later in the season

The hypothesis that larger male body size confers fitness advantages in mating success, commonly observed in insects where large size increases competitive ability

Individuals kill unrelated young to avoid wasting energy on parental care that does not benefit their own offspring

The hypothesis that parent-offspring conflicts can arise when host plants that maximize larval performance differ from plants that increase adult longevity and egg production
