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 impo...
Soil respiration is perhaps one of the most important in the many different processes of the carbon cycling in natural and cultivated ecosystems. The aim of this study was to measure intensively the soil respiration fluxes in two native Cerrado vegetation types, that differ in...
Resumo: Analisou-se o potencial das imagens TM/Landsat-5, ETM+/Landsat-7, CBERS/CCD e IKONOS como base de dados para reforma agrária. Os resultados mostraram que a imagem IKONOS apresentou o melhor desempenho técnico, entretanto, o custo de aquisição impede sua ampla utilização como...
Estima-se que 60% do Cerrado, segundo maior bioma na América do Sul, já tenham sido convertidos em função da intensa atividade agropecuária existente na região. Por outro lado, poucas tem sido as iniciativas voltadas ao monitoramento sistemático deste bioma. Neste sentido, e no âmb...
The dynamic of nitrogen oxides emissions from Cerrado soils related to the nitrogen fertilization is still not well known, in spite of the intensification of agricultural activities in this region. NO and N2O emissions were measured immediately and up to five days after nitrogen&#x...
The composition and activity of soil microbial communities largely determine biogeochemical cycles, the turnover process of organic matter, and the fertility and quality of solis. Plant communities can influence associated soil microbial communities through the types and amounts of C and nut...
The savanna in Brazil, locally known as “cerrado,” is the most intensely stressed biome with both natural environmental pressures and rapid/aggressive land conversions. Large-scale vegetation characterization of the biome is needed in order to improve our understanding of the human impact&#x...
O sistema de Integração da Restauração Ecológica à Pecuária (IRPE) é uma metodologia inovadora que consiste em usar bovinos, em manejo adequado, para estabelecimento do componente florestal se beneficiando do serviço ambiental prestado pelo gado por meio do pastejo, minimizando a competição&...
An experiment was carried out in pots with a soil mixed with six powdered silicate materials originated from mining (kyanite, biotite schist, biotite syenite, basalt, vermiculite, or bentonite). These sources were mixed in 4.4 kg of soil (Anionic Acrustox) at the rates of 0 (c...
Soil loss stands as a critical global challenge, posing economic and environmental threats to soil and water conservation. This study aimed to assess the impact of landscape changes on soil loss in the Descoberto River basin, encompassing 62 watersheds in the Cerrado biome in ...
