Contrasting trends of population size change for two Eurasian Owlet species - Athene brama and Glaucidium radiatum from South Asia over the late Quaternary

This study aims to understand the impacts of past climactic fluctuations, particulalry the over the late Quaternary, on the population size trends of two phylogenetically close, yet ecologically distinct species of Owlets in India. We use the Pairwise Sequential Markovian Coalescent (PSMC) approach on whole genome data from the two species to examine effective population size changes over time.

本研究旨在探究古气候波动（尤其是第四纪晚期的古气候波动）对印度两种系统发育亲缘关系较近但生态特征显著分化的小鸮种群数量动态变化趋势的影响。我们采用成对序列马可夫共祖分析（Pairwise Sequential Markovian Coalescent, PSMC）方法，基于这两个物种的全基因组数据，分析其有效种群大小随时间的变化情况。
