Extended Data Fig. 3: Historical and recent species richness versus sampling area.
From: Accelerated increase in plant species richness on mountain summits is linked to warming
Historical species richness was exceeded within a small sampling area during recent resurveys. Species richness of the historical survey (yellow) contrasted with a species richness accumulation curve of the recent surveys on summits where the highest occurrence of each recent species was estimated to the nearest 1-m elevation. The number of species found historically within the uppermost 10 m of a summit was exceeded within the uppermost 5 m in the most recent resurveys. This analysis includes all 157 European summits for which such data are available, regardless of whether the historical species number was reached in recent times. The blue circle visualizes average species richness of the recent surveys within the uppermost 10 m.
