TERMITES AS MEDIATORS OF THE WATER ECONOMY OF ARID SAVANNA ECOSYSTEMS

2006
Large termite mounds, constructed by colonies of various species of macrotermitine termites (Isoptera, Termitidae, Macrotermitinae), are dominant features of the arid and semiarid savannas of southern Africa. These mounds can populate a savanna in very high densities, generally one to four colonies per hectare, containing biomass of termites and ...

Thornbush invasion in a savanna ecosystem in eastern Botswana

Vegetatio, 1984
The paper describes the thornbush invasion (bush encroachment) found in the savanna at Olifants Drift in eastern Botswana. Overgrazing by cattle is responsible for the opening up of the grass sward and has enabled woody species to establish. A quantification of this process between 1950 and 1975 in an area of ca.

Is Succession a Viable Concept in African Savanna Ecosystems?

1981
The savannas of Southern and East Africa have five major characteristics that together distinguish them from other ecosystems: 1. Both the herbaceous and woody layers contribute significantly to primary production, and they generally occur in an irregular mosaic. 2. The vegetation is spatially very heterogeneous. 3.

Quantifying changes in vegetation heterogeneity in a savanna ecosystem

2022
Vegetation heterogeneity is crucial to sustaining herbivore populations in a savanna ecosystem, but increasing anthropogenic pressures in recent years have led to land degradation and homogenization (Hunter et al. 2020, Russell et al. 2018). This paper examines vegetation heterogeneity in the Olkirimatian-Shompoli ecosystem, a case study of the ...
