Burning for birds : the response of bird communities to recent fire history in the Serengeti ecosystem
… process with important implications for savanna ecology and conservation. In this study we aimed to explore the short-term and long-term effects of recent fire history on bird communities in the greater Serengeti savanna ecosystem in Tanzania. The study investigated the influence of …

Gardens Are for Cash, Grain Is for Life: The Social Organization of Parallel Production Processes in a Rural Bamana Village (Mali)
… regional political economy and the challenges of savanna ecology. Finally, I suggest that the pattern of coexistence between domestic group food farming and market gardening depends on and strengthens long-standing inequalities between men and women, and seniors and juniors. This study makes …

Up in smoke: biomass burning and atmospheric emissions in the Sudanian savanna of Côte d’Ivoire
… at the local and regional scales in the sudanian savanna of Côte d’Ivoire. Fire is an important management tool in farming and pastoral systems of West Africa. The climate change literature argues that biomass burning is an important source of greenhouse gases, chemically active gases, and …

Spatial and temporal variability in Acacia population dynamics
… the coexistence of trees and grasses in savannas and impact upon savanna structure, which also varies substantially both spatially and temporally. These features can shape savannas at an ecosystem and even at a global scale, but mechanisms for the effects of fire, herbivory, and climate …

Managing herbivory over space and time: consequences for vegetation and cattle responses in African rangelands
… cattle, I first explored evidence from paleoecology, historical literature and savanna ecology to test the hypothesis that mid-Holocene African savannas were dominated by herbivory as a means of cycling nutrients and changing vegetation whereas fire perhaps played a lesser role than it does …

Savanna dynamics under extreme conditions
Savannas cover a broad geographical range across continents and are a biome best described by a mix of herbaceous and woody plants. The former create a more or less continuous layer while the latter should be sparse enough to leave an open canopy. What has long intrigued ecologists is how these two …
