Extended Data Fig. 4: Effects of key predictors on the response to increasing grazing pressure (resistance).
From: Plant diversity enhances ecosystem resistance to increasing grazing pressure in global drylands
Structural equation model showing the relationships among aridity (estimated as 1-Aridity Index), herbivore richness, soil sand content, relative woody cover, latitude, plant species richness, and resistance (estimated as a log response ratio: ln[vegetation cover high grazing pressure/vegetation cover low grazing pressure]). Numbers on arrows are fully standardized path coefficients. Blue and red arrows indicate positive and negative relationships, respectively. Asterisks indicate significance level: ** p<0.01 and *** p<0.001.
