Spatial distribution of soil δ13C in the central Brazilian savanna

Journal of Environmental Management, 2021
Stable carbon isotope ratios (δ13C) of soil record information regarding C3 and C4 plants at the landscape scale that can be used to document vegetation distribution patterns. The Central Brazilian savanna (locally called the Cerrado) has a substantial potential to develop studies of patterns of dynamics and distribution of soil δ13C, due to its ...

Legacy phosphorus and no tillage agriculture in tropical oxisols of the Brazilian savanna

Science of the Total Environment, 2016
Crop production in the Brazilian Cerrado is limited by soil phosphorus (P) supply without large inputs of inorganic P fertilizer, which may become more costly and scarce in the future. Reducing dependency on fertilizer P requires a greater understanding of soil P supply in the highly weathered soils in this important agricultural region.

Putting fire on the map of Brazilian savanna ecoregions

Journal of Environmental Management, 2021
The Brazilian savanna (Cerrado) is considered the most floristically diverse savanna in the world, home to more than seven thousand species. The region is a mosaic of savannas, grasslands and forests whose unique biophysical and landscape attributes are on the basis of a recent ecoregional map, paving the way to improved region-based strategies for ...

The assessment of multi-sensor image fusion using wavelet transforms for mapping the Brazilian Savanna

International Journal of Applied Earth Observation and Geoinformation, 2006
Multi-sensor image fusion using the wavelet approach provides a conceptual framework for the improvement of the spatial resolution with minimal distortion of the spectral content of the source image.

Brazilian Savanna Height Estimation Using UAV Photogrammetry

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Unmanned aerial vehicles (UAVs) have been advancing in precision and cost-benefit for remote sensing studies, including height and biomass estimations. This article presents a preliminary experiment to explore UAV photogrammetry to estimate canopy height in savanna and grassland phytophysiognomies in the Brazilian Cerrado biome.

Diversity of Archaea in Brazilian savanna soils

Archives of Microbiology, 2013
Although the richness of Bacteria and Fungi in Cerrado' soils has been reported, here we report, for the first time, the archaeal community in Cerrado's soils. DNA extracted from soil of two distinct vegetation types, a dense subtype of sensu strict (cerrado denso) and riverbank forest (mata de galeria), was used to amplify Archaea-specific 16S rRNA ...
