Brazilian Savanna Height Estimation Using UAV Photogrammetry
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Unmanned 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.

Putting fire on the map of Brazilian savanna ecoregions
Journal of Environmental Management, 2021The 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 ...

Diversity of Archaea in Brazilian savanna soils
Archives of Microbiology, 2013Although 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 ...

Aquatic ecotoxicity of ashes from Brazilian savanna wildfires
Environmental Science and Pollution Research, 2017In a global scenario of climate change, several studies have predicted an increase in fires in different parts of the world. With the occurrence of rains following the fires in the Brazilian savanna (Cerrado biome), the compounds present in ashes may enter aquatic environments and cause adverse effects to these ecosystems.

Spatial distribution of soil δ13C in the central Brazilian savanna
Journal of Environmental Management, 2021Stable 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 ...

Odonata Concordance amongst aquatic taxa in brazilian savanna streams
International Journal of Odonatology, 2022Environmental management is one of the most important activities in ecological conservation at present. Faced with various socioeconomic impacts (e.g., urbanization, agriculture, and logging), practical and effective ways to analyze and determine how biodiversity is affected by these anthropogenic activities are essential.

Expansion of gallery forests into central Brazilian savannas
Global Change Biology, 2008AbstractUpland tropical forests have expanded and contracted in response to past climates, but it is not clear whether similar dynamics were exhibited by gallery (riparian) forests within savanna biomes. Because such forests generally have access to ample water, their extent may be buffered against changing climates.

Fires in the cerrado, the Brazilian savanna
2009The cerrado is the largest area savanna formation in South America, and originally covered approximately 25% of the Brazilian territory. The savanna forms of cerrado are characterized by a ground layer of grasses, small palms, shrubs, and trees.
