Figure 4. Dot plot of multivariate homogeneity of groups dispersions (betadisper) of Batrachoseps attenuatus skin microbiota samples collected in Quercus agrifolia and Eucalyptus globulus dominant habitats.

Each point represents the bacterial skin community of an individual sample; point color indicates dominant vegetation of the habitat (Black—Quercus agrifolia and gray—Eucalyptus globulus) and shape indicates site identity (square—site 1, triangle—site 2, and diamond—site 3). Significant differences are marked with asterisks (* if 0.01 < p < 0.05, ** if 0.001 < p < 0.01, and *** if p < 0.001).
