  1. The ensembles of species belonging to common environmental categories are analyzed. The average distances and the fraction of small distances of the ensembles are compared to 10000 random sets of species of the same size as the corresponding ensembles. The expected value for the mean distance between two points is , while the expected value for the fraction of small distances by definition is . As for Table 1, the -values were determined by comparing the distribution of the corresponding values for the random ensembles with the actually observed value for the selected ensembles. See Supplementary Figure S9 for more details.
