摘要

Introduction: Carbon isotopes techniques in soil organic matter (SOM) for identification and changing distribution of C_3 and C_4 plant communities (i.e., forest vs savanna vegetation) and inferences related to humid and drier paleoclimatic conditions, respectively, have been applied on regional studies from the Amazon basin to the southern region of Brazil and elsewhere (e.g., Boutton, 1996; Desjardins et al., 1996; Pessenda et al, 1996a, b, 1998a, b, 2001a, 2004a, b, c; Freitas et al., 2001; Gouveia et al., 2002).
