Table 8.
Character loadings, eigenvalues, and percentage of explained variance for Principal Components (PC) I–II. The analysis was based on six morphometric variables of adult Hypsiboas alfaroi, Hypsiboas almendarizae, Hypsiboas calcaratus, Hypsiboas fasciatus, Hypsiboas maculateralis, and Hypsiboas tetete. Bold figures indicate highest loadings.
