Table 6 in Cryptic diversity in toads of the Rhinella marina species group (Anura, Bufonidae) with a subjectively beautiful new species from Western Ecuador

Table 6. Loadings, eigenvalues, and percentage of explained variance for four first PCs from a PCA. The analysis is based on 19 climatic variables (BIO1–BIO19) from 98 collection localities of three toad populations’ specimens used for the phylogenetic analysis (see Material and methods section)
