Non-parametric multiple regression to test for multiple effects on AMF phylogenetic diversity (AMF MPD)
| Source | Estimates | d.f. | F | R2 | P-value |
|---|---|---|---|---|---|
| Plant MPD | −3·9 × 10−6 | 1 | 2·2 | 0·03 | 0·61 |
| Patch nursery quality | −2·9 × 10−2 | 1 | 0·0 | 0·00 | 0·98 |
| Plant PC1 | −1·2 × 10−2 | 1 | 16·5 | 0·28 | 0·005 |
| AMF PC1 | 4·0 × 10−3 | 1 | 23·0 | 0·39 | 0·002 |
| Plant MPD × patch nursery quality | 1·02 × 10−4 | 1 | 6·0 | 0·10 | 0·031 |
| Residuals | 11 | 0·18 | |||
| Total | 16 |
The model tests for the relative contribution of plant mean phylogenetic distance (plant MPD), community-weighted mean of nursery quality (patch nursery quality), plant and AMF phylogenetic composition (plant PC1 and AMF PC1) and the interaction of plant phylogenetic diversity and nursery quality.
