From: The strength of soil-plant interactions under forest is related to a Critical Soil Depth
Strength of models (using explained variance) across different soil depth columns explaining productivity (biomass) and community assembly (Shannon diversity, Evenness, Phylogenetic diversity and species richness) of tree (dark dots) and herb (bright dots) layer. The maximum LOWESS fit characterizes the optimum soil depth (dashed dark grey line and dashed light grey line symbolizes fit to tree and herb layer, respectively). Solid black line symbolizes fit across both layers. Solid light grey line shows depth-specific maximum of fit.
