Historic duck DNA traces wild mallard genetic changes to more than a century of releases

Researchers have long known that releasing domesticated ducks can alter wild populations. Now, a study led by a doctoral student at The University of Texas at El Paso has documented, for the first time in North America, when and where these genetic changes took place and tied them directly to more than a century of releases.
