Lingering genetic evidence of North American mallards (Anas platyrhynchos) introduced to New Zealand
Introduced species are becoming part of the landscape around the world. Unfortunately, in many cases, the exact source population for these introduced species is not known, which can hamper their proper management. Genetic investigations can shed light on the introduction process and we used the New Zealand mallard (Anas platyrhynchos) population as a case study to demonstrate the insights that genetics can provide.
