Supplement 1. Data showing results for eight analyses consisiting of rare species trajectories analyses 1 and 2, community divergence using pair-wise comparisons analyses 1–3, and community divergence from a regional species pool analyses 1–3, along with the analysis summary table.

File List Rare_species_analysis_1.txt Results for “Rare Species Trajectories Analysis 1; Do the rarest species in the least isolated sites decline or increase with increasing isolation?” Rare_species_analysis_2.txt Results for “Rare Species Trajectories Analysis 2; Are there more rare species in the least or most isolated sites?” Pairwise_comparison_analysis_1.txt Results for “Community divergence using pair-wise comparison Analysis 1; Is geographic distance or environmental distance correlated with community divergence across all sites?” Pairwise_comparison_analysis_2.txt Results for “Community divergence using pair-wise comparison Analysis 2; Is geographic and environmental distance correlated with community divergence in the most or least isolated subsets of sites?” Pairwise_comparison_analysis_3.txt Results for “Community divergence using pair-wise comparison Analysis 3; Is community divergence highest at intermediate patch isolation?” Regional_comparison_analysis_1.txt Results for “Community divergence from a regional species pool Analysis 1; Are environmental or isolation variables correlated with community distance from the regional community, using all sites?” Regional_comparison_analysis_2.txt Results for “Community divergence from a regional species pool Analysis 2; Does variance of community distance from a regional pool differ between the least and most isolated subsets of the data?” Regional_comparison_analysis_3.txt Results for “Community divergence from a regional species pool Analysis 3; Does the amount of variation explained by environmental parameters differ between the most and least isolated subsets of patches?” Summary_across_analyses.txt A summary of responses across all analyses Description Tab-delimited tables detailing results for eight analyses and the summary across analyses. Tables include (depending on analysis) P and q values for each level of region, year, growth-type, isolation and guild, plus sample sizes, effect sizes, and a column summarizing the response. The first rows of each file define the column headings.

数据集说明
本数据集包含8项分析结果及跨分析汇总结果，均以制表符分隔的表格文件形式存储。根据分析类型的不同，表格涵盖区域、年份、生长型、隔离程度以及功能群各水平下的P值与q值，同时包含样本量、效应量以及响应结果汇总列。每个文件的首行用于定义列标题。
