Table 3.
Relationship between the phylogenetic originality of a host species (HPO) and either the species richness (FSR) or phylogenetic diversity of its flea assemblage (MPD or MNTD) in 4 biogeographic realms (only significant models are shown)
| Realm | Diversity metric | Equation | R2 | F | P |
|---|---|---|---|---|---|
| Afrotropics | FSR | 0.13 − 0.24 × HPO | 0.06 | 9.22 | 0.003 |
| Palaearctic | FSR | 0.14 − 0.20 × HPO | 0.04 | 7.54 | 0.007 |
| Australasia | MNTD | 0.52 − 0.42 × HPO | 0.07 | 7.35 | 0.008 |
| Nearctic | MPD | 0.62 + 0.29 × HPO | 0.04 | 7.45 | 0.006 |
| MNTD | 0.50 + 0.40 × HPO | 0.08 | 15.27 | 0.0001 |
MPD, mean pairwise distance; MNTD, mean nearest-taxon distance (Tucker et al., 2017).
