Spatial distribution of soil δC in the central Brazilian savanna.

Stable carbon isotope ratios (δC) of soil record information regarding C and C plants at the landscape scale that can be used to document vegetation distribution patterns. The Central Brazilian savanna (locally called the Cerrado) has a substantial potential to develop studies of patterns of dynamics and distribution of soil δC, due to its environmental diversity. The purpose of this work was to develop a spatial model of soil δC (soil δC isoscape) to the Cerrado, based on multiple linear regression analysis, and compare the results with the existing model to obtain greater detail of the soil δC distribution.
