10. "Respiração do solo sob florestas e pastagens na Amazônia Sul-Ocidental, Acre" / soil respiration under forests and pastures in Southwestern Amazonia, Acre
Conversion of forest to cattle pastures and subsequent abandonment of those pastures is occurring throughout the Amazon Basin, but the biogeochemical consequences of this land cover change are not well understood. In this study we assess the effects of land-use change on soil respiration in pastures, secondary forests and mature forests near Rio Branco, Acre
