利用近亲标记再捕获估算有效种群数量
近亲标记-重捕(CKMR)是一种通过观察近亲(包括亲代-后代配对(POPs)和半同胞配对(HSPs))数量来估算种群普查规模和其他参数的方法。CKMR 模型能够利用不同组群的 POPs 和 HSPs 估算丰度、繁殖力和年龄存活率。有效种群数量(Ne)与 "同群内 "同胞配对数量之间的联系以前就被注意到过,但如何利用 CKMR 实际实现这种估算,以前还没有被证明过。我们的研究表明,可以使用 "同群内 "同胞配对的数量以及持久性有机污染物和 "不同群 "HSP 来估计 Ne。这些数据可以与后代数量年方差的估计值结合起来,以估计总繁殖成功率的终生方差,并可用来计算 Ne。我们的研究表明,成虫在特定年份繁殖后代数量的方差与同群内比较有关。我们在一个基于个体的模拟中演示了我们的方法,结果表明,CKMR Ne 估计结果与联系不平衡等方法估计的 Ne 结果相似。我们的方法允许使用 CKMR 估算 Ne,同时也能估算人口参数。

期刊介绍: A British Ecological Society journal, Methods in Ecology and Evolution (MEE) promotes the development of new methods in ecology and evolution, and facilitates their dissemination and uptake by the research community. MEE brings together papers from previously disparate sub-disciplines to provide a single forum for tracking methodological developments in all areas. MEE publishes methodological papers in any area of ecology and evolution, including: -Phylogenetic analysis -Statistical methods -Conservation & management -Theoretical methods -Practical methods, including lab and field -This list is not exhaustive, and we welcome enquiries about possible submissions. Methods are defined in the widest terms and may be analytical, practical or conceptual. A primary aim of the journal is to maximise the uptake of techniques by the community. We recognise that a major stumbling block in the uptake and application of new methods is the accessibility of methods. For example, users may need computer code, example applications or demonstrations of methods.
