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. Columns include:countriesWithHosts: number of countries where the pest and hosts co-occurcountrySaturation: proportion of potential host countries where pests occurntaxa: number of host taxampdses/mpdPval: mean pairwise distance standard effect size and p-valuemntdses/mntdPval: mean nearest taxon distance standard effect size and p-valuePD: host phylogenetic diversityPSV: Phylogenetic species variability of hostsPSR: Phylogenetic species richness of hostsPSE: Phylogenetic species evenness of hostsPSC: Phylogenetic species clustering of hostsPest 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.
