Differences in the advertisement calls of Microhyla fissipes between populations sympatric with and allopatric to M. heymoni
| Effect | Num DF | Den DF | PC1 | PC2 | ||
|---|---|---|---|---|---|---|
| F | P | F | P | |||
| Sympatry versus allopatry | 1 | 9 | 0.28 | 0.61 | 0.65 | 0.44 |
| Ambient temperature | 1 | 130 | 23.75 | <0.0001 | 1.50 | 0.22 |
| SMI | 1 | 130 | 0.66 | 0.42 | 0.14 | 0.70 |
PC1 is the temporal properties and PC2 the spectral properties of the calls. Ambient temperature is the temperature at the time of call recording, and SMI is the scaled body mass index of the caller. The sample locality nested in the type of population (sympatry vs. allopatry) was included as a random effect.
