Evidence that metapopulation dynamics maintain a species' range limit

This zip folder includes both raw data from a multi-year (2019 and 2022) survey of coastal dune habitat and occupancy by Camissoniopsis cheiranthifolia, as well as an R project and associated scripts for an analysis of variation in metapopulation dynamics towards a species' range limit.本ZIP压缩文件夹包含两类资料：其一为针对海岸沙丘生境及Camissoniopsis cheiranthifolia占据情况开展的2019年与2022年多年调查所获原始数据；其二为用于分析物种分布范围极限处集合种群动态变异的R语言项目及配套脚本。
