Tussock and Savanna Ecosystems
2020This chapter focuses on Chinese tussock and savanna rangeland ecosystems. It introduces in brief the areal extent and provincially based distribution of this ecosystem type; simply discusses the relevant physical features and climatic characteristics at a regional scale; elaborates in great detail the flora, fauna, and microflora composing the various ...

Abstract Great herds of wildebeest, big cats, the great tuskers and the all but extinct rhino are the images that epitomize the savannas of Africa. The savannas of Africa are occupied by the earth’s’ richest and most spectacular large mammal fauna, a sizable proportion of which is found in East Africa.

Science of The Total Environment, 2022
Restoration of savanna ecosystems within their historic range is expected to increase provision of ecosystem services to resident human populations. However, the benefits of restoration depend on the degree to which ecosystems and their services can be restored, the rate of restoration of particular services, and tradeoffs in services between restored ...

ON TERMITARIA IN A SAVANNA ECOSYSTEM
Canadian Journal of Zoology, 1965During the course of a quantitative phytosociological analysis of the vegetation of the Northern Rupununi Savanna, British Guiana, the termitaria were measured by the Quarter Method of the Wisconsin School in a manner similar to that for trees. The ecological distribution of the termitaria was found to be correlated with quantitative expressions of ...

On the carrying capacity for large ungulates of African savanna ecosystems
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1994The effect of pastoral management on the standing crop biomass of large ungulates, an index of carrying capacity, is analysed at a regional level by using data compiled from published sources covering east and south Africa. The effect of primary production is controlled for by using two environmental factors, rainfall and soil nutrient availability ...

Dynamics of savanna ecosystems
Journal of Vegetation Science, 1992Theories concerning the factors involved in the dynamics of savannas, particularly the tree-grass interface, are reviewed. Emphasis is put on factors related to soil moisture, soil nutrients, fire and large herbivores. The distinction be- tween external (independent) and internal (dependent, interac- tive) environment is discussed and it is explained ...

Agroecological restoration of savanna ecosystems
Ecological Engineering, 1998Abstract As a result of deforestation, annual bush burning, overgrazing and intensive cultivation, most tropical forests have changed to derived savanna in many West African states. This change in vegetation has led to a decrease in rainfall and a change in many climatic conditions.

Estimation of erodibility in the savanna ecosystem, northern Ghana
Communications in Soil Science and Plant Analysis, 1995Abstract This paper discusses the concept of erodibility being one of the main parameters needed for erosion risk assessments as well as presents some measurements of erodibility in the savanna ecosystem, northern Ghana, based on three different indices: aggregate stability, shear strength, and the Consistency Index. The study revealed that the overall
