Performance curves for Zonation analyses (Maxent, CAZ, all species together). Left panel is without PA integration. Solid curves represent the average performance curve for all species or per species-group; while dashed lines represent the overall minimum and maximum performance curve per species group. The vertical grey line is for urban and agricultural areas (Additional file 1: Figure S2) forced to have low priority value; while the dashed vertical green line represents top priority sites existent in an area equals to the area covered by PAs. The right panel represents equivalent analysis with Egyptian PAs forced to have the highest priority scores. The vertical green line represents the area covered by PAs; while the vertical orange line represents the proposed areas for PAs expansion to 17% of Egypt. Performance curves are described in Additional file 1: Figure S1 and in the main text. For equivalent curves using ABF, see Additional file 1: Figure S10. Results for elastic net are shown in Additional file 1: Figure S11
