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.
