Edaphic, structural and physiological contrasts across Amazon Basin forest–savanna ecotones suggest a role for potassium as a key modulator of tropical woody vegetation structure and function
Sampling along a precipitation gradient in tropical South America extending from ca. 0.8 to 2.0 m a<sup>−1</sup>, savanna soils had consistently lower exchangeable cation concentrations and higher C / N ratios than nearby forest plots. These soil differences were also reflected in...
