Figure 2. Threshold responses along LUI gradient for different taxa diversity and ecosystem functions. On the left, response to land use intensity (LUI) of all variables considered, including above- and belowground diversity, and ecosystem functions. Different colors indicate different responses to LUI (red/orange = negative response; blue = positive response; grey = no response; vascular plant diversity always decreased with land use intensity but the strength of that decline was lower after the threshold, which is indicated as a shift from red to orange). * indicates a variable showing a threshold response. On the right, one example of threshold response for above- (plants) and belowground diversity (fungal decomposers), and ecosystem function (N retention).
