a significant trendp = .001
We also observed a significant trend of increased absolute divergence with distance between populations of H. erato – H. e. chestertonii (Mantel's test: R 2 = .44; p = .001), H. melpomene – H. cydno (Mantel's test: R 2 = .69; p = .001) and H. melpomene – H. timareta (Mantel's test: R 2 = .56; p = .001).
