本文描述了当代两种群间成虫迁移数量和迁移速率估计器的发展。所提出的估计是基于已知的半兄弟姐妹（HS）和/或父母-后代（PO）关系，观察到不同繁殖季节种群之间的关系。其基本原理是HS和PO对显示了在繁殖间隔期间亲本运动发生频率的信息。所提出的方法允许每个亲本在种群内和种群间的平均后代数量的差异。此外，结合种群内发现的PO对，仅使用遗传数据即可获得估计量。一般来说，样本量代表人口规模的平方根是获得有意义的迁移信息所必需的。我们通过运行基于个体的模型对所提出的估计器的性能进行了详细的评估，结果提供了关于样本量的指导，以确保所需的准确性和精度。此外，鉴于很少有有效的方法来估计成虫的运动（特别是当种群不能遗传不同时），我们讨论了所提出的亲属分配方法在保护生物学和野生动物管理方面的有用性。
This paper describes the development of estimators for the contemporary migration number and rate of adults between two populations in iteroparous species. The proposed estimators are based on known half‐sibling (HS) and/or parent–offspring (PO) relationships observed between populations across breeding seasons. The rationale is that HS and PO pairs exhibit information about the occurrence frequency of parental movements during the breeding interval. The proposed method allows for variance in the average number of offspring per parent within and between populations. In addition, coupled with the PO pairs found within the population, the estimators can be obtained using only genetic data. Generally, a sample size representing the square root of the population size is required to obtain meaningful migration information. We describe a detailed evaluation of the performance of the proposed estimators by running an individual‐based model, and the results provide guidance regarding sample sizes to ensure the required accuracy and precision. In addition, given that there are few effective methods to estimate adult movement (especially when populations cannot be genetically distinct), we discuss the usefulness of the proposed kinship assignment method in terms of conservation biology and wildlife management.
