Species Richness Patterns and Water-Energy Dynamics in the Drylands of Northwest China
Figure 6
Structural equation models (SEM) of vertebrate and plant richness and climatic predictors.
SEMs were conducted for mammals (a, b, c) and birds (e, f, g) in the entire Xinjiang (a, e) and in the low (b, f) and high (c, g) energy regions, respectively. (d) and (h) show the comparisons between the effects of plant richness (blue bars) and the total direct effects of climate (AET+PET) (orange bars) on vertebrate richness in the entire Xinjiang, low and high energy regions, respectively.
