Extended Data Table E2 Multi-linear model equations with stepwise predictor selection and model fit to derive the three soil variables of Table 1.

From: Biodiversity and ecosystem functions depend on environmental conditions and resources rather than the geodiversity of a tropical biodiversity hotspot
