Figure 1. Variation in alpha diversity (A–C) and beta diversity (D–F) of the bacterial communities on the skin of Coqui frogs (Eleutherodactylus coqui) from seven sites varying in elevation and land use. Analyses of elevation (C, F) exclude one unpaired site from the highest elevation zone (Bosque Enano).

Ordinations were constructed using non-metric multidimensional scaling based on Jaccard dissimilarities of relative abundance data (stress = 0.15 for D, E and also 0.15 for F).
