Figure 3 The linear relationships between the relative changes in multi-diversity and ecosystem multifunctionality (EMF) under light grazing (LG), moderate grazing (MG) and heavy grazing (HG), respectively. The shade represents confidence intervals (CI). The significance indicated as ***P <0.001 **P <0.01 and *P <0.05. The interactive effect of grazing intensity (GI) and multi-diversity on EMF obtained from the linear mixed effect model are shown.
