Figure 6.

Correlation of habitat environmental factors with physical characteristics of pill bugs (Edge widths indicate Mantel’s r statistics corresponding to distance correlations, and edge colors indicate statistical significance based on 9999 permutations showing pairwise comparisons of physical characteristics with environmental factors. The color gradient in the box indicates Pearson’s correlation coefficient, the magnitude of which is proportional to the r-value, and the number indicates Pearson’s r-value. The “*” means p < 0.050; The “**” means p < 0.01 for Pearson correlation.)
