Proportions of among-caves variances in phenotypes accounted for by ecological variables, genetic distances, and not explained by either of those. Phenotypes were PC scores for body shape (PC1, 3, and 5, top row) and head shape (PC1, 2, and 3, bottom row), and genetic distances were Cavalli distance matrix (Dce; referred as G). Environmental variables (E) were the number of openings, the minimal distance to the lake and the annual average water temperature in each cave. Proportion of variance that was not explained by either of those refers to “others” (O)
