TABLE 2.
Summary of the phylogenetic structure of low, middle and high-altitude species in Taiwan.
| MPDphylo | ||||
| Altitude | N | Actual | Nulls (mean ± sd) | P |
| Low | 399 | 268.1 | 267.0 ± 3.0 | 0.639 |
| Middle | 186 | 267.8 | 267.1 ± 5.7 | 0.54 |
| High | 142 | 260.6 | 267.0 ± 6.8 | 0.174 |
| MNTDphylo | ||||
| Low | 399 | 94 | 93.3 ± 2.1 | 0.645 |
| Middle | 186 | 106.4 | 111.8 ± 4.2 | 0.098 |
| High | 142 | 105.3 | 118.9 ± 5.0 | 0.004 |
The P-value is determined by the rank of the actual MPDphylo (or MNTDphylo) in 1000 nulls MPDphylo (or MNTDphylo). Larger P-value indicates stronger phylogenetic over-dispersion, while lower P-value indicates stronger phylogenetic cluster. Phylogenetic distance calculated from the phylogenetic tree was the distance analyzed here.
