Pair-wise tests of coincidence among morphological clines of cranial crest separation in toads.

Pair-wise tests of coincidence among morphological clines of cranial crest separation in toads during different time periods, among habitat clines between forest and prairie during different time periods, and between clines in toad morphology and habitat at most closely comparable time periods. Likelihood Ratio Test (LRT) values are above the diagonal and probability (P) values are below the diagonal. Asterisks (*) indicate significant difference at α = 0.05. Daggers (†) indicate significant difference following sequential Bonferroni correction for multiple independent tests.
