Abstract

e comprehension of species responses to climate change is one of our present ecological challenges. is paper aims to evaluate the demographic responses of a Southern Giant Petrel population according to climate factors. We used a Multi-State Mark-Recapture method to estimate survival from breeder and non-breeder, and transition rates. Breeder survival response to Southern Oscillation Index, Antarctic Oscillation Index and temperature. Non breeder survival response to Southern Oscillation Index and temperature and Desertion rate with response to Temperature only in summer. Southern Giant Petrels are associated with warmer sea conditions. No recent decrease caused by climate factors can be expected under the scenario of warming in Antarctic Peninsula, and actual population size makes this assumption reasonable.
南极巨型海燕种群对气候变化的响应
了解物种对气候变化的反应是我们当前面临的生态挑战之一。本文旨在根据气候因素评估南巨海燕种群的人口响应。我们使用多状态标记-重新捕获方法来估计繁殖者和非繁殖者的存活率以及过渡率。南方涛动指数、南极涛动指数和温度对育种者存活率的影响。非繁殖体存活率对南方涛动指数和温度的响应,以及仅在夏季对温度的响应。南方巨海燕与温暖的海洋环境有关。在南极半岛变暖的情景下,预计近期不会出现气候因子导致的减少,而实际的人口规模使这一假设合理。
