Extended Data Figure 5: Partial effects of geographic and environmental distances and temporal variation in LUI on β-diversity above- and belowground.
From: Land-use intensification causes multitrophic homogenization of grassland communities
a, b, Results from GDMs are shown for seven aboveground and five belowground groups, with total β-diversity measured as the Sørensen index βsor (a) or as the species turnover component βsim (b). The figures show the effect of differences in each of the five variables on β-diversity (calculated between all plot pairs; n = 105 plots). Effects of differences in each explanatory variable can vary nonlinearly along the gradient of that variable and each is corrected for all other variables in the model. Higher maximum curves indicate larger effects of differences in a given variable on β-diversity. Soil nutrients refer to the scores of the first PCA axis. Temporal variation in LUI is shown as s.d. Geographic distance has to be multiplied by 100 km.
