Table 5 Summary of pairwise Mantel's tests on inter-populational distance matrices. Matrices used in each test were derived from CVA of call and morphological variables, and from straight-line geographic distances between collecting localities. Top number in each cell is r (correlation coefficient), bottom is p-value. Comparisons marked by an asterisk were significant after sequential Bonferroni adjustment. Each matrix uses ranked values but the results are unchanged with raw (unranked) values
