Asymmetric response of above- and below ground biomass of C3- and C4-dominated grasslands to aridity

Journal of Water and Climate Change, 2023
Assessing the dynamics of grassland functioning is critical for gaining an understanding of their feedback on rising aridity. In attempting to understand the response of grassland ecosystem functioning to aridity, the (i) relationships between biomass ...

Dynamics of Sudanian savanna-woodland ecosystem in response to disturbances [PDF]

, 2007
Grazing, fire and selective tree cutting are major disturbances shaping species diversity and productivity in savanna-woodland ecosystems. Their effects, however, are highly variable and poorly understood.

Land-use diversity within an agricultural landscape promotes termite nutrient cycling services in a southern African savanna

Global Ecology and Conservation, 2020
Soil macrofauna provide key supporting ecosystem services by transporting nutrients against physical and chemical gradients. In the semi-arid savannas of southern Africa, termites are the dominant macrofauna whose foraging activities increase nutrient ...

Qualitative Modeling for Bridging Expert-Knowledge and Social-Ecological Dynamics of an East African Savanna

Land, 2021
Sub-Saharan social-ecological systems are undergoing changes in environmental conditions, including modifications in rainfall pattern and biodiversity loss. Consequences of such changes depend on complex causal chains which call for integrated management

Quantifying the relative importance of greenhouse gas emissions from current and future savanna land use change across northern Australia [PDF]

Biogeosciences, 2016
The clearing and burning of tropical savanna leads to globally significant emissions of greenhouse gases (GHGs); however there is large uncertainty relating to the magnitude of this flux.

Challenges and opportunities in modelling savanna ecosystems [PDF]

, 2016
Abstract. The savanna complex is a highly diverse global biome that occurs within the seasonally dry tropical to sub-tropical equatorial latitudes. Savannas are open-canopy environments that encompass a broad demographic continuum, often characterised by a dynamically changing dominance between C3-tree and C4-grass vegetation, where frequent ...
