Spatial distribution of wood volume in Brazilian savannas [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2019
Here we model and describe the wood volume of Cerrado Sensu Stricto, a highly heterogeneous vegetation type in the Savanna biome, in the state of Minas Gerais, Brazil, integrating forest inventory data with spatial-environmental variables, multivariate regression, and regression kriging.

Phylogenetic overdispersion of plant species in southern Brazilian savannas [PDF]

open access: yesBrazilian Journal of Biology, 2009
Ecological communities are the result of not only present ecological processes, such as competition among species and environmental filtering, but also past and continuing evolutionary processes. Based on these assumptions, we may infer mechanisms of contemporary coexistence from the phylogenetic relationships of the species in a community.

Simulating the Effect of Fire Frequency on the Vegetation Biomass and Carbon Emissions in the Brazilian Savanna: BEFIRE Model

open access: yesBiodiversidade Brasileira, 2019
The Brazilian Cerrado is the savanna with the greatest biodiversity in the world. The adequate definition of fire frequency is a key factor for the success of savanna management, since frequent fires and in a short time interval may prevent the recovery

Quantifying Fire-Induced Surface Climate Changes in the Savanna and Rainforest Biomes of Brazil

open access: yesFire, 2023
This study uses a combined research approach based on remote-sensing and numerical modeling to quantify the effects of burned areas on the surface climate in the two Brazilian biomes most affected by fires: the tropical savanna and the Amazon rainforest.

Analysis of fire dynamics in the Brazilian savannas [PDF]

open access: yes, 2017
Abstract. Wildfires play a key role in the ecology of savannas. The Brazilian savannas (Cerrado biome), where the extension of burned areas and amount of fires can be more numerous than in the Amazon, is frequently burned due to natural fires or land-use and land-cover (LULC) changes.
