背景情况:

大型猛禽的种群轨迹对成人的生存率很敏感.
准确的生育率,成熟度和生存率估计对于有效的保护至关重要.
金 (Aquila chrysaetos) 的保护需要了解它们的生存动态.

研究的目的:

通过使用DNA分析,估计苏格兰地区金的明显生存率.
调查性别和地区对金生存的影响.
建立一种新的方法来识别和估计该物种的个体存活率.

主要方法:

从的羽毛中提取DNA,以对金个体进行基因分析.
在四年 (2006-2009) 的时间里,在巢穴附近收集的羽毛.
使用Cormack-Jolly-Seber模型估计年度明显生存率,并结合性别和区域数据.

主要成果:

男性每年明显生存率 (0.774-0.808) 明显低于女性 (0.878-0.882).
男性的遭遇率低于雌性,这表明在巢穴附近的时间较少.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
