Fig. 5: Fitted relationships between each diversity metric and anthropogenic land use for North American and European biomes for data encompassing the period 8,000–100 cal yr bp.
From: Floristic diversity and its relationships with human land use varied regionally during the Holocene
Relationships shown are for those biomes within North America (left-hand panels) and Europe (right-hand panels) that met the inclusion criteria, encompassing the period 8,000–100 cal yr bp (Methods). Lines represent median fits across 1,000 resamples; shaded intervals represent interquartile ranges across 1,000 resamples. Note that anthropogenic land use is back transformed. Heterogeneity is calculated by Bray–Curtis. Diversity axis ranges are consistent within but not between continents. Grey land surface areas are not considered. NA tundra n = 872, EU tundra n = 1,016, NA boreal forests/taiga n = 1,725, EU boreal forests/taiga n = 1,704, NA temperate conifer forests n = 3,204, EU temperate conifer forests n = 3,816, NA temperate broadleaf and mixed forests n = 5,002, EU temperate broadleaf and mixed forests n = 22,666, NA temperate grasslands, savannas and shrublands n = 1,242, EU Mediterranean forests, woodland and scrub n = 2,834.
