Equivalence and similarity tests in environmental space for P. boliviensis and P. depilata A PCA of ecological climatic B the variables contribution to the analyses C graphical results of the equivalency and similarity permutation tests comparing the two species of Phoneutria. Line marks and filled squares are the available environment in each range (M) and occupied space by each species, respectively. Occupied climatic niche by P. boliviensis, P. depilata and niche overlap (D) are in green, red and blue colors, respectively.
