Area - population relationships for Adelie Penguin colonies at Mawson.

The relationship between colony area and population density of Adelie Penguins Pygoscelis adeliae was examined to determine whether colony area, measured from aerial or satellite imagery, could be used to estimate population density, and hence detect changes in populations over time. Using maps drawn from vertical aerial photographs of Adelie Penguin colonies in the Mawson region, pair density ranged between 0.1 and 3.1 pairs/m2, with a mean of 0.63 - 0.3 pairs/m2. Colony area explained 96.4% of the variance in colony populations (range 90.4 - 99.6%) for 979 colonies at Mawson. Mean densities were not significantly different among the 19 islands in the region, but significant differences in mean pair density were observed among colonies in Mawson, Whitney Point (Casey, East Antarctica) and Cape Crozier (Ross Sea) populations.

本研究围绕阿德利企鹅（Pygoscelis adeliae）的繁殖群落面积与种群密度的关联展开分析，旨在验证通过航空或卫星影像测得的繁殖群落面积是否可用于估算种群密度，进而实现种群随时间的动态变化监测。
本研究采用莫森区域阿德利企鹅繁殖群落的垂直航空摄影制图数据，结果显示该区域繁殖对密度介于0.1至3.1对/平方米之间，平均密度为0.63±0.3对/平方米。针对该区域的979个繁殖群落，群落面积可解释种群数量96.4%的变异（变异幅度为90.4%~99.6%）。该区域内19个岛屿的平均种群密度无显著差异，但莫森、惠特尼角（南极东部凯西地区）与克罗泽角（罗斯海）的企鹅种群之间，平均繁殖对密度存在显著差异。
本研究作为ASAC项目1219（ASAC_1219）的一部分完成。本数据集包含以下字段：岛屿、纬度、经度、调查日期、繁殖群落面积、繁殖配对数、每平方米繁殖配对数、单巢占用面积、巢穴总数、成年个体总数。
