Supplement 1. Simulated data sets of traits and initial and ultrametric distances used for Figs. 3 and 4.
Fig.3&4_Data_Files.zip -- (all files at once) zip file containing simulated data sets (in .txt files) of traits, initial and ultrametric distances used for Figures 3 and Fig. 4.
For both figures, the 5 species traits values to compute the simulated assemblages of 20 species were randomly sampled among a log-normal distributions with mean 0 and standard deviation 1 (available in files Fig3_Data-Species_traits.txt and Fig4_Data-Species_traits.txt). Initial distances were computed by mean of the Euclidean distance (available in files Fig3_Data-Initial_Euclidean_distances_D.txt and Fig4_Data-Initial_Euclidean_distances_D.txt). Ultrametric distances were then provided by single linkage and UPGMA clustering algorithms (available in files Fig3_Data-Ultrametric_distances_U_Single_Linkage.txt, Fig3_Data-Ultrametric_distances_U'_UPGMA.txt, and Fig4_Data-Ultrametric_distances_U_Single_Linkage.txt, Fig4_Data-Ultrametric_distances_U'_UPGMA.txt).
