Adelie penguin dive data 1999-2009 from the California Avian Data Center hosted by Point Reyes Bird Observatory Conservation Science

This project is an international collaborative investigation of geographic structuring, founding of new colonies, and population change of Adelie penguins (Pygoscelis adelia) nesting on Ross and Beaufort islands, Antarctica. This ongoing study will continue to consider the relative importance of resources that constrain or enhance colony growth (nesting habitat, access to food); the aspects of natural history that are affected by exploitative or interference competition among neighboring colonies (breeding success, foraging effort); climatic factors that influence the latter, especially sea ice patterns; and behavioral mechanisms that influence colony growth as a function of initial size and location (emigration, immigration). The research includes a census of known-age penguins, studies of foraging effort and overlap among colonies; and identification of the location of molting and wintering areas.

本项研究系一项国际协作的南极地区地理结构研究项目，旨在探究罗斯岛和波弗特岛上的阿德利企鹅（Pygoscelis adelia）的筑巢分布、新殖民地的建立以及种群变迁。该研究将持续考量资源对殖民地增长（巢穴栖息地、食物获取）的相对重要性；邻近殖民地间因利用性或干扰性竞争而受影响的自然历史方面（繁殖成功率、觅食努力）；影响后者的气候因素，尤其是海冰模式；以及影响殖民地增长作为初始规模和位置的函数的行为机制（迁徙、移民）。研究内容涵盖已知年龄企鹅的普查、对觅食努力和殖民地间重叠的研究；以及识别换羽和越冬地区的位置。
