Abstract Catch rates of Yellow Perch Perca flavescens in standard gill‐net surveys
conducted by the Minnesota Department of Natural Resources have declined since 1970 …

Phenotypic plasticity, the ability of a single genotype to produce different phenotypes under
different environmental conditions, plays a profound role in several areas of evolutionary …

Population dynamics and ecological effects of invasive fishes are affected by offspring
survival to sexual maturity (recruitment). Recruitment is oftentimes determined by conditions …

Resource polymorphism is common across taxa and can result in alternate ecotypes with
specific morphologies, feeding modes, and behaviors that increase performance in a …

Phenotypic plasticity is common among animal taxa. While there are clearly limits and likely
costs to plasticity, these costs are unknown for most organisms. Further, as plasticity is …
