Understanding phenotypic diversity requires not only identification of selective factors that
favor origins of derived states, but also factors that favor retention of primitive states. Anurans …

Amphibian communities at 178 ponds across southwestern Ontario, Canada, were studied
to determine if presence of predatory fish was related to altered amphibian species richness …

typically focused on “hard” components of life histories; phenotypic characteristics that can …

Environmental heterogeneity can cause the intensity and direction of selection to vary in
time and space. Yet, the effects of human‐induced environmental changes on sexual …

In many organisms reproductive success is strongly dependent on several breeding site
