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
