Resumo: | ABSTRACT: In the Cerrado Biome, the internal carbon cycling, the main carbon pools size, and the fluxes intensity between carbon pools are far from to be completely understood. This study presents the main carbon pools and cycling fluxes in terrestrial ecosystems, emphasizing the neotropical savannas. This study will also review literature of internal carbon cycling in the Cerrado. In spite of the science advances, the knowledge of internal carbon dynamics in the Cerrado are scarce. The relation between the carbon pools size and fluxes intensity and the Cerrado's vegetation phytofisionomies, soil gradient, and climate still remains unknown. The carbon pools and fluxes data analysis show that the Cerrado's aerial carbon pools are smaller than the forest systems pools. However, the subterranean carbon pools are equal or greater than the high production forest systems. Scientific estimations showed that 2,050 Pg of carbon (1 Pg=10 (elevado a 15) g, or one billion tons) would be stocked in terrestrial ecosystems and 70% of it would be stocked soils. These data showed that soil is an important atmospheric carbon source and cleaner. In other natural and cultivated exosystems in the Cerrado Biome, the subterranean process needs more studies.
