High Latitude Breeding

这项研究项目涉及野外和实验室研究鸟类对北极环境中普遍存在的极端条件的生理和行为适应。这项研究将集中在格陵兰岛和阿拉斯加的地点发现的四种鸟类，它们代表了一系列恶劣的极地条件。将确定不同环境对繁殖的影响，以检查气候的作用。血液样本和类固醇治疗将被用来检验关于环境条件对睾酮产生的作用及其对繁殖季节生殖行为的影响的假设。研究结果将被用来检验气候条件变化对迁徙到北极的鸟类繁殖行为的潜在影响，例如全球变暖。

This research project involves field and laboratory studies on the physiological and behavioral adaptations of birds to the extreme conditions that prevail in Arctic environments. The study will focus on four bird species found at sites in Greenland and Alaska that represent a series of harsh polar conditions. The effect of different environments on breeding will be determined in order to examine the role of climate. Blood samples and steroid treatment will be used to test hypotheses about the role of environmental conditions on testosterone production and its effect on reproductive behavior during the breeding season. The results will be used to examine the potential effects of changing climate conditions, such as global warming, on the breeding behavior of birds that migrate into the Arctic.
