An interaction between coat colour phenotype and environment affected (A) |mean nearest taxon distances| (box-cox transformed) (city versus rural), and (B) β mean nearest taxon distance (βMNTD_ses) (built-environment versus forest), such that city and built-environment agouti squirrels had values closer to stochastic expectations. Dotted horizontal lines denote values beyond two standard deviations from the null distribution. Solid horizontal lines within violins denote the interquartile range. Horizontal brackets and ‘*’ denote significant differences in βMNTD_ses variance homogeneity using permutation tests (p < 0.05)
