Adelie penguin satellite position data 2000-2009 from the California Avian Data Center hosted by Point Reyes Bird Observatory Conservation Science

Abstract: 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.

摘要：本项目为一项国际合作研究，旨在调查栖息于南极洲罗斯岛与博福特岛的阿德利企鹅（*Pygoscelis adelia*）的地理种群结构、新种群建立及种群动态变化。本项持续推进的研究将持续关注以下核心内容：限制或促进种群增长的各类资源的相对重要性（包括筑巢栖息地、食物获取途径）；受相邻种群间利用性竞争与干扰性竞争影响的自然历史特征（包括繁殖成功率、觅食投入）；影响上述特征的气候因素，尤其是海冰格局；以及依据种群初始规模与地理位置调控种群增长的行为机制（包括迁出、迁入）。本研究涵盖已知年龄个体的种群普查、各群体间觅食投入与觅食重叠情况的分析，以及换羽区与越冬区位置的识别工作。
