Legend:

ID = Identifier from MGRS (Military grid reference system 100 km × 100 km)

mean_RGB = Coverage weighted mean RGB of colour lightness values of co-occurring species (grid cells)

RGB_P_comp = Phylogenetically predicted component of the mean_RGB of co-occurring species (grid cells)

RGB_S_comp = Deviation of mean_RGB from phylogenetically predicted component of co-occurring species (grid cells)

Longitude = Longitude of grid cell centroids (EPSG:4326, longlat)

Latitude = Latitude of grid cell centroids (EPSG:4326, longlat)

Sp_rich = Number of species per grid with colour lightness data

SES_CLD = Colour lightness diversity: Standardized effect sizes of mean pairwise distances of co-occurring species (grid cells) minus a null model of 1,000 alternative species sets with the same number of species randomly drawn from the species pool.
