Temporal Population Genetic Structure of Yellow Perch Spawning Groups in the Lower Great Lakes

摘要: AbstractThis study tested the hypothesis that genetic composition of Yellow Perch Perca flavescens spawning groups at specific sites remained consistent among years or age-cohorts; this likely would influence spatial population structure and be important for delineating management units. Previous studies identified genetically differed locations across fine geographic scales, but it was unknown whether these patterns persisted from year to year. We analyzed 15 nuclear DNA microsatellite loci six Lake Erie in 2009 reference two out-groups Lakes St. Clair Ontario. Results were compared with a prior samples same had been collected various years, ranging 2001 2005. evaluated consistency multiple birth-year-cohorts. indicated levels diversity similar all years. All eight spawn...
