| dc.description | During the past decade, the increasing knowledge about the effects of natural and cultivated ecosystems on regional and global climate raised the importance of terrestrial ecosystem to function either as carbon source or sink. The aim of this study was to measure the most important pools and fluxes of the internal carbon cycling in two native Cerrado vegetation types, that differ in tree density (cerrado denso and cerrado stricto sensu) and one planted pasture, in an effort to produce a synthesis of our knowledge about Cerrado carbon cycling. The native Cerrado ecosystems are located in the Reserva Ecológica do Roncador (RECOR/IBGE), in Brasília, DF, Brazil, while the planted pasture (Brachiaria brizantha) is located in the experimental fields of Embrapa-Cerrados, in Planaltina, DF, Brazil.. Synthesis of estimations of the main pools and fluxes were made by combining direct field measurements, data from the literature , and modeling results. The native ecosystems showed very similar pools and fluxes. Pools in living tissues of pasture were much smaller than natural ecosystems, while soil organic matter was slightly larger in the pasture. The fluxes were faster in the pasture. The intensity of fluxes intensity in the pasture, makes the carbon dynamics of this ecosystem very sensitive to management practices. | |
