Extended Data Fig. 5: Site-level (pollen record) estimates of millennial changes in diversity over three 1850 year periods over the Holocene: The early Holocene, mid Holocene and the Common Era.
From: Floristic diversity and its relationships with human land use varied regionally during the Holocene
a) turnover (Bray-Curtis), b) turnover (Jaccard), c) richness, d) evenness. Values computed by regressing each diversity measure onto age (calibrated years bp), extracting the slope coefficients and multiplying them by 1000 to give the expected linear change in diversity per millennium (on the log and logit scale for richness and evenness/turnover, respectively). Box and whiskers represent the cohort of pollen records from each continent. Plots are zoomed in for clarity of presentation, but retain 95% of slope estimates. In the following, ‘EH’ represents Early Holocene, ‘MH’ represents Mid Holocene and ‘CE’ represents Common Era: Africa EH n = 111, MH n = 334, CE n = 669; Asia EH n = 176, MH n = 626, CE n = 715; Australasia EH n = 85, MH n = 171, CE n = 149; Europe EH n = 3,864, MH n = 11,320, CE n = 9,827; North America EH n = 2,476, MH n = 4,514, CE n = 4,123; South America EH n = 198, MH n = 676, CE n = 908.
