The effect of niche filtering on plant species abundance in temperate grassland communities

The dataset contains 3 files: 1. "metadata.xls": It contains the necessary information to interpret the other files. 2. "sites_x_species.csv": It contains the list of species and their abundances in sampled vegetation plots. 3. "sites_x_predictor.csv": It contains the macroclimatic variables (PCA axes) in each vegetation plot, and their classification into grassland vegetation types.
