A Century of Hybridization: Decreasing Genetic Distance Between American Black Ducks and Mallards

  author={Judith E. Mank and John E. Carlson and Margaret C. Brittingham},
  journal={Conservation Genetics},
American black ducks (Anas rubripes) and mallards (A. platyrhynchos) are morphologically and behaviorally similar species that were primarily allopatric prior to European colonization of North America. Subsequent sympatry has resulted in hybridization, and recent molecular analyses of mallards and black ducks failed to identify two distinct taxa, either due to horizontal gene flow, homoplasy, or shared ancestry. We analyzed microsatellite markers in modern and museum specimens to determine if… CONTINUE READING
