Regeneration traits are structuring phylogenetic diversity in cork oak (<i>Quercus suber</i>) woodlands Export

We recorded all woody species and geographical features on 94 (20 m × 20 m) plots of cork oak woodlands.

PD was computed as the minimum total length of all the phylogenetic branches spanning the set of species on each site.

Species richness and PD are strongly related; however, the remaining variability can be explained by: (1) precipitation and disturbance, and (2) the proportion of seeder species. Thus, the PD both of areas with low precipitation and high disturbance, and of areas with a high representation of seeder species, is lower than what would be expected from the species richness.
