Fig. 3: Biogeographic origins of invasive species of Poaceae.

From: Contrasting patterns in phylogenetic and biogeographic factories of invasive grasses (Poaceae) across the globe

Fig. 3

A Biplot display of invasive species generated per floristic region with the aggregated numbers of emergence by biogeographic realm (blue gradient) and biome (red gradient). The basemap of Earth was taken from ArcGIS-licensed software. Purple colours indicate high contribution in both terms, thus highlighting areas that act as important invasive species factories. Dark blue areas indicate weak biome contributors within alien-rich realm factories of invasives. Dark red areas indicate strong biome factories of invasives at poor realm contributors. B, C Standardized numbers of invasive species production per biome/realm factory size, per regional biome/realm richness of Poaceae species pool (in the phylogeny) and the accumulated total phylogenetic diversity (PD) of the invasive species community per biome/realm, respectively.
