Demographic History of the Gentoo Penguin (Pygoscelis papua) and the Adélie Penguin (Pygoscelis adeliae) on Admiralty Bay, King George Island, Antarctica

摘要: Abstract. There is growing evidence that during the past 100 years climate of Antarctic Peninsula has changed from a relatively cold environment to an increasingly warmer one. The penguins breed in region are sensitive oceanographic environmental and climatic conditions. They considered bellwether sentinels ocean because their sensitivity changes. present study aimed determine evolutionary history Gentoo Penguin (Pygoscelis papua) Adelie adeliae) at Admiralty Bay, King George Island. A population genetics approach was used examine genetic variability two penguin species, searching infer demographics histories. D-loop mitochondrial DNA sequenced (n = 53) 29) penguins. These species showed high diversity, reflecting large ancestral size. results also revealed had stable over ...
