Introduction A characteristic of tropical savanna is the co-dominance of trees and grasses (Frost et al., 1986). In savannas, diurnal temperatures are high and rainfall is distinctly seasonal with a warm wet season and a cool dry season during which soil moisture in the upper layers of the soil falls by as much as 80% (Williams et al., 1997; Oliveira et al., 2005; Archibald et al., 2019).

AbstractThe determinants of fire-driven changes in soil organic carbon (SOC) across broad environmental gradients remains unclear, especially in global drylands. Here we combined datasets and field sampling of fire-manipulation experiments to evaluate where and why fire changes SOC and compared our statistical model to simulations from ecosystem models.

AbstractTropical savannas have been increasingly targeted for carbon sequestration by afforestation, assuming large gains in soil organic carbon (SOC) with increasing tree cover. Because savanna SOC is also derived from grasses, this assumption may not reflect real changes in SOC under afforestation. However, the exact contribution of grasses to SOC and the changes in SOC with increasing tree cover remain poorly understood.
