Roots take up labeled nitrogen from a depth of 9 m in a wooded savanna in Brazil
(2021-01-01)
The savannas (called Cerrado) are the second-largest vegetation formation in Brazil after the Amazon rainforest, with about 2 million km2. Roots have been found in very deep soil layers in Cerrado ecosystems, which suggests ...
Resource Availability Shapes Fire-filtered Savannas
(WILEY-BLACKWELLHOBOKEN, 2015)
Woody plant encroachment constrains regeneration of ground-layer species in a neotropical savanna from seeds
(2022-01-01)
Woody plants have been encroaching into savannas on a global scale. Global climatic changes, along with changes to disturbance regimes, are considered to be the main drivers of this process. Particularly, many formerly ...
Fire promotes functional plant diversity and modifies soil carbon dynamics in tropical savanna
(2022-03-15)
Fire is an evolutionary environmental filter in tropical savanna ecosystems altering functional diversity and associated C pools in the biosphere and fluxes between the atmosphere and biosphere. Therefore, alterations in ...
SPATIAL VARIABILITY OF THE PROPERTIES OF COHESIVE SOILS FROM EASTERN MARANHAO, BRAZIL
(Soc Brasileira De Ciencia Do Solo, 2014-07-01)
The national and international demand for maps of soil properties has increased. The aim of this study was to characterize cohesive soils and associate their variability of particle size, chemical properties, and color to ...
Can savannas become forests? A coupled analysis of nutrient stocks and fire thresholds in central Brazil
(2013-07-26)
Aims: The effects of fire ensure that large areas of the seasonal tropics are maintained as savannas. The advance of forests into these areas depends on shifts in species composition and the presence of sufficient nutrients. ...
