Global extent and composition of tree pests

Data used in "Host phylogenetic diversity predicts the global extent and composition of tree pests." Separate datasheets are available for genus- and species-level pest hosts. <br>Columns include:<b>countriesWithHosts:</b> number of countries where the pest and hosts co-occur<b>countrySaturation:</b> proportion of potential host countries where pests occur<b>ntaxa:</b> number of host taxa<b>mpdses/mpdPval:</b> mean pairwise distance standard effect size and p-value<b>mntdses/mntdPval:</b> mean nearest taxon distance standard effect size and p-value<b>PD:</b> host phylogenetic diversity<b>PSV:</b> Phylogenetic species variability of hosts<b>PSR:</b> Phylogenetic species richness of hosts<b>PSE:</b> Phylogenetic species evenness of hosts<b>PSC:</b> Phylogenetic species clustering of hosts<br>Pest species with only one host have NA's for host range information. Pests with zero saturation, have only been reported in countries outside the native range of their hosts.
