Extended Data Figure 8: Effects of single land-use components on β-diversity above- and belowground.
From: Land-use intensification causes multitrophic homogenization of grassland communities
a, c, e, Partial effects of minimum LUI (min LUI) and ΔLUI between plot pairs (n = 105 plots), on the species turnover component of β-diversity (βsim) for seven aboveground and five belowground groups based on linear models. Negative effects of minimum LUI indicate that land-use intensification reduces β-diversity. The bars show coefficients from the models. Numbers adjoining bars are the proportion of the total explained variance that is uniquely explained by minimum LUI orΔLUI among plot pairs, on the basis of hierarchical partitioning. b, d, f, Results from GDMs are shown for the turnover component βsim for the same trophic groups. The figures show the effect of ΔLUI on β-diversity (calculated between all plot pairs). Effects of ΔLUI can vary nonlinearly along the gradient of LUI. Higher maximum curves indicate larger effects of ΔLUI on β-diversity. The values in the legend are the percentage of deviance that is explained uniquely by LUI. Effects of both linear models and GDMs are corrected for other drivers of β-diversity, and response and explanatory variables are scaled to allow comparisons across trophic levels (see Methods).
