Data matrices for ethnoflora analysis

It contains four matrices. Two are presence-absence matrices (0, 1), used for a Jaccard dissimilarity analysis. The first contains the data for analyzing the dissimilarity in the species that make up the ethnofloras (SppEtnia_Jaccard). The second contains the data for analyzing the dissimilarities in the uses of species shared between ethnic groups (usos_Jaccard). The scripts for the Jaccard analyses are located in the supplementary section. The other two matrices were used for a Mantel test analysis. The first matrix contains the geographic distance between ethnic groups, and the second contains the linguistic distance between the ethnic groups.
