The Savanna Biomes (Mesic/Dystrophic and Arid/Eutrophic) of Angola cover over 90% of the country. This Chapter presents the case for the recognition, across Africa, of these two distinctive savanna biomes, both defined by the co-dominance of fire-tolerant trees and C4grasses, falling within s...
Shrubs generally occur within the savanna near sources of water and along the slopes of hills. Sickle bush (Dichrostachys cinerea) is one of the most common shrubs in the savanna, found along brackish waterways and in roadside ditches. It is a small, densely matted bush growing to si...
The long-term Quaternary vegetation and climate history in South Africa’s savanna biome since ca. 190,000 yr BP, is elucidated by the palynological record of lake sediments in the Tswaing Crater (the Pretoria Saltpan), and spring deposits from Wonderkrater, despite hiatuses in ...
The two groups of cultivars and their associated hives were separated by ~ 150 m of natural vegetation (lowveld region of the savanna biome). For measurement of nectar concentrations, we selected 10 trees from each cultivar and pooled the nectar from 10 florets per raceme (total 30 ...
Chapter 15 The Arid Savanna Biome Key Concepts and Questions: This Chapter Will Explain • Why soil nutrient status, moisture relations and herbivory are the key drivers of arid savanna structure and function. • How to define, recognise and understand the concept of 'arid/eutrophic' savannas...
While previous researchers have addressed isotopic variability amongst plants, no studies have looked extensively at a broad suite of taxa over multiple temporal scales from within the savanna biome so as to provide baseline data for palaeodietary and palaeoenvironmental studies. Here we document ...
Relationship between woody biodiversity and use of non-timber forest products in the Savanna Biome of South Africa 来自 ResearchGate 喜欢 0 阅读量: 29 作者:B Delali,K Dovie 摘要: This study seeks to combine the knowledge of science and society to elicit the relationshipbetween the harvesting of...
We quantified transpiration and drought tolerance traits in 26 tree and 19 grass species from the African savanna biome across a gradient of soil water potentials to test for a trade-off between water use under wet conditions and drought tolerance. We measured whole-plant hourly transpiration in ...

Southern Africa comprises a mosaic of biomes, including some typical of the African continent, such as the Savanna Biome, as well as biomes that are geographically restricted, in particular, the Mediterranean Fynbos Biome, where most of the coastal and near-coastal sites are found (one notable ...
