TABLE 1.
Evaluating the effect of habitat (bamboo and non‐bamboo) and size (evolutionary allometry) on the skull shape of bush frogs using phylogenetic generalized least‐squares (PGLS) analysis (shape ~log (size) × habitat).
| df | SS | R 2 | F | Z | p | |
|---|---|---|---|---|---|---|
| Log (Size) | 1 | 0.003 | .042 | 2.320 | 1.928 | .021 |
| Habitat | 1 | 0.002 | .019 | 1.060 | 0.425 | .365 |
| Log (Size): habitat | 1 | 0.003 | .031 | 1.776 | 1.038 | .154 |
| Residuals | 53 | 0.079 | .908 | |||
| Total | 54 | 0.086 |
Note: Random residual permutations (1000) were used to estimate statistical significance (Bolded p shows significance; p < .05).
Abbreviations: df, degrees of freedom; PGLS, phylogenetic generalized least‐squares; SS, sum of squares.
