Shifting roles of the East China Sea in the phylogeography of red nanmu in East Asia

This dataset contains one README file and two raw data files on the distribution and genetic data described in the paper: Jiang et al. (2021) Shifting roles of the East China Sea in the phylogeography of Machilus thunbergii (Lauraceae) in East Asia. Journal of Biogeography.
Ecological niche modeling was employed to predict the potential distribution of M. thunbergii during the Last Glacial Maximum (LGM) and the last interglacial period. Nuclear microsatellite and chloroplast markers were used to reveal the phylogeographic pattern and infer the population history of 33 M. thunbergii populations.
The ecological niche models suggested that the ECS provided potentially suitable habitats for M. thunbergii during the LGM. A sharp change in cpDNA haplotypes was found along the eastern China coasts, while microsatellites revealed a clinal pattern for genetic composition from eastern China to central Japan. The divergent lineages formed an admixture on the Zhoushan Archipelago of China and Kyush...

本数据集包含1个README文件及2个原始数据文件，内容涉及论文《东海在东亚樟科红楠（Machilus thunbergii）系统地理学中的角色转变》（Jiang等，2021，《生物地理学杂志》）中描述的分布与遗传数据。
研究采用生态位模型（Ecological niche modeling）预测末次盛冰期（Last Glacial Maximum, LGM）及末次间冰期红楠的潜在分布。利用核微卫星（nuclear microsatellite）与叶绿体标记（chloroplast markers）揭示33个红楠种群的系统地理格局，并推断其种群历史。
生态位模型结果显示，末次盛冰期东海为红楠提供了潜在适宜生境。中国东部沿海地区的叶绿体DNA（cpDNA）单倍型存在显著变化，而微卫星数据揭示了从中国东部到日本中部遗传组成的渐变模式。分化支系在中国舟山群岛及Kyush...形成混合群。
