Table 2 in Cryptic diversity in toads of the Rhinella marina species group (Anura, Bufonidae) with a subjectively beautiful new species from Western Ecuador

Table 2. Loadings, eigenvalues, and percentage of explained variance for first two PCs of a PCA. This analysis was based on seven acoustic variables from the advertisement calls of 35 toads from western Ecuador (R. bella), eastern Ecuador (R. marina), and Central America (R. horribilis). Additionally, one from eastern Peru was included in the analysis
