Sensitivity of woody carbon stocks to bark investment strategy in Neotropical savannas and forests [PDF]

Biogeosciences, 2018
Fire frequencies are changing in Neotropical savannas and forests as a result of forest fragmentation and increasing drought. Such changes in fire regime and climate are hypothesized to destabilize tropical carbon storage, but there has been little ...

Effect of Maize Conservation Crops Associated with Two Vegetal Covers on the Edaphic Macrofauna in a Well-Drained Savanna of Venezuela

Land, 2022
Conventional agricultural in the Venezuelan Llanos has generated gradual soil degradation. Therefore, conservationist agriculture has been proposed. According to several works, this type of management favors soil macrofauna.

What are we planting in ecological restoration of tropical open ecosystems? A systematic review of controlled experiments [PDF]

Acta Botânica Brasílica
Tropical grasslands, savannas, and shrublands comprise open ecosystems that are experiencing growing anthropogenic pressures and lack theoretical and practical knowledge on ecological restoration. Natural regeneration in these ecosystems is very slow and

The impacts of fire on birds in Australia's tropical savannas

, 2015
The ecology of Australia's tropical savannas is shaped by the near-pervasive influence of fire. Constituting ∼20% of Australia's land area, tropical savannas contribute >75% of the area burnt in Australia each year. Across most of Australia's tropical

Patterns of Water and Heat Flux Across a Biome Gradient From Tropical Forest to Savanna in Brazil [PDF]

, 2009
We investigated the seasonal patterns of water vapor and sensible heat flux along a tropical biome gradient from forest to savanna. We analyzed data from a network of flux towers in Brazil that were operated within the Large-Scale Biosphere-Atmosphere ...

Rainfall and topographic position determine tree embolism resistance in Amazônia and Cerrado sites

Environmental Research Letters, 2023
Droughts are predicted to increase in both frequency and intensity by the end of the 21st century, but ecosystem response is not expected to be uniform across landscapes.

The influence of tropical grass species on soil nitrification and denitrification across savanna ecosystems

Geoderma
Although limited by nutrient-poor soils primary productivity in certain humid savannas can be as high as in tropical forests. This high productivity can be partly attributed to the ability of certain perennial grasses (Poaceae) to inhibit nitrification ...
