-Data description:
The elasticity of substitution (theta) represents the degree to which species can substitute for each other in contributing to forest productivity; theta measures the marginal productivity—the change inproductivity resulting from one unit decline of species richness—and reflects the strength of the effect of tree diversity on forest productivity, after accounting for climatic, soil, and plot-specific covariates.
A higher theta corresponds to a greater decline in productivity due to one unit loss in biodiversity.
