Table 4. Character loadings, eigenvalues, and percentage of explained variance for Principal Components (PC) I–II of specimens of the D. leucophyllatus-triangulum complex.
| Character Loading | ||
|---|---|---|
| Variable | PC I | PC II |
| Type I note duration | 0.56 | 0.25 |
| Number of pulses of the Type I note | 0.53 | 0.31 |
| Rise time of the Type I note | 0.43 | 0.2 |
| Frequency bandwidth | –0.28 | 0.68 |
| Dominant frequency | –0.35 | 0.57 |
| Eigenvalue | 2.59 | 1.23 |
| % | 51.82 | 24.62 |
The analysis was based on five acoustic variables from the advertisement calls of Dendropsophus arndti sp. n., D. leucophyllatus, D. triangulum, D. reticulatus comb. nov., D. sp. D, D. sp. F, and D. sp. G. Bold figures indicate the highest loadings.
