Fig. 4: Richness hotspot overlap.
From: Global divergence in plant and mycorrhizal fungal diversity hotspots
Richness hotspots (top 95th percentile of richness predictions) for vascular plants (green), arbuscular mycorrhizal (AM) fungi and ectomycorrhizal (ECM) fungi (purple). Areas where plant and fungal hotspots overlap are shown in pink. Hotspots are mapped individually for the four previously published alpha diversity geospatial layers26,27,28,29 (and not the consensus richness maps), and hotspot or overlap areas identified by more than one study are shaded darker. Dark grey areas are those included in the analysis; light grey areas were excluded due to high uncertainty in the original alpha diversity predictions or where predictions for each taxonomic group by different studies strongly disagreed (mostly based on the coefficient of variation between bootstrap model replicates; see ‘Methods’). Blue bars show how hotspot overlap area is distributed across biomes. A breakdown of the hotspot areas for each individual geospatial layer is provided in Supporting Information Fig. S7, and maps of hotspots recalculated at the biome level (i.e. top 95th percentile within each biome) are provided in Figs. S9 and S10.
