Recruitment synchrony of yellow perch (Perca flavescens, Percidae) in the Great Lakes region, 1966–2008
Population-level reproductive success (recruitment) of many fish populations is
characterized by high inter-annual variation and related to annual variation in key
environmental factors (eg, climate). When such environmental factors are annually
correlated across broad spatial scales, spatially separated populations may display
recruitment synchrony (ie, the Moran effect). We investigated inter-annual (1966–2008)
variation in yellow perch (Perca flavescens, Percidae) recruitment using 16 datasets …
