Relationships between soil properties, FFI and AGB of grassy (AGBGRASS) and woody (AGBWOOD) layers.

Relationships between soil properties, FFI and AGB of grassy (AGBGRASS) and woody (AGBWOOD) layers. (a–d) Influence of soil texture (clay and silt content), fertility (CEC) and FFI on AGBGRASS. (e, f) Influence of FFI on the woody layer with its effects on the relationship between AGBWOOD and AGBGRASS. Colours denote plots located on granite (red) and metamorphic (green) substrates. Broken and unbroken lines, respectively, represent the 95th and 50th nonlinear piece-wise quantile regressions. The unbroken orange curve in (f) shows the mean FFI along the gradient of AGBGRASS.
