From: Host phylogeny and environment shape the diversity of salamander skin bacterial communities
Association between salamander phylogenetic distances and skin bacterial community dissimilarity. a Bacterial dissimilarity (Y-axis) at the order level as a function of host species evolutionary distances (X-axis) estimated by fossil-based molecular dating of the best-scoring ML tree of extant salamanders. The solid black line represents the slope estimated with a Mantel test between matrices. b Correlogram showing the variation in the Mantel correlation coefficients as a function of host species evolutionary distances (in millions of years). Open circles connected by a solid black line represent the correlations estimated with the best-scoring ML tree. Solid circles represent the correlations estimated with evolutionary distances using the fossil-based molecular dating of the bootstrap trees. Colours are indicative of the corresponding p-values of correlations
