Molecular demographic history of the Hainan Peacock Pheasant (Polyplectron katsumatae) and its conservation implications

摘要: Knowledge of the historical responses animal species to climate changes is critical for understanding their evolutionary history and conservation. During late Quaternary period, Southeast Asia had a larger land area than today due lower sea levels, its terrestrial landscape was covered by extensive forests savannah. To date, however, general fluctuations in distribution impacts on demographics native during periods are still disputed. Specifically, animals Hainan Island, which located northernmost region Asia, changes, poorly understood. Here, we performed series demographic analyses based mitochondrial DNA genes examine response resident Peacock Pheasant (Polyplectron katsumatae) change. Unlike pattern population collapse ice age expansion warming detected through period. It concluded that survived periods, despite currently limited size Island. Anthropogenic influences must be considered conservation planning fragmented habitats populations. phylogeography, Quaternary, Polyplectron katsumatae,
