Table 7. Character loadings, eigenvalues and percentage of explained variance for Principal Components (PC) I–IV. The analysis was based in eleven environmental variables extracted from presence localities of 26 species of Pristimantis, subgenus Huicundomantis. Bold figures indicate highest loadings.
