Fig. 4From: Environmental niche unfilling but limited options for range expansion by active dispersion in an alien cavity-nesting waspEstimate of the potential dynamics of invasion risk areas through time (i.e., combining current and future model outputs), based on the projections of the extreme values of Minimum Temperature of the Coldest Month and Precipitation of Driest Quarter (IPPC5 climate projections using the CCSM4 global climate model). Violet grid points: potential distribution under current conditions; Green grid points: potential distribution under future conditions. Green grid points were made sufficiently transparent to highlight areas of overlap with violet grid points. a Projection for 2050 under the RCP 8.5 concentration pathway; b projection for 2070 and RCP 8.5 concentration pathwayBack to article page
