Holocene vegetation change and the mammal faunas of South America and Africa
Aim: Although sharing many similarities in their vegetation types, South America and Africa harbour very dissimilar recent mammal faunas, not only taxonomically but also in terms of several faunistic patterns. However late Pleistocene and mid-Holocene faunas, albeit taxonomically distinct, presented many convergent attributes. Here we propose that the effects of the Holocene climatic change on […]
Diet and Feeding Effects of Introduced Giraffe in the Eastern Cape.
This study presents the results of a study on introduced giraffe diet and feeding effects within the Eastern Cape Province of South Africa. Five sites were selected over a moisture gradient from the mesic east to the arid west of the Eastern Cape to describe giraffe diet and provide baseline data for feeding effect experiments. […]
Browsing Lawns? Responses of Acacia Nigrescens to Ungulate Browsing in an African Savanna
We measured browsing-induced responses of Acacia trees to investigate ‘‘browsing lawns’’ as an analogy to grazing lawns in a semiarid eutrophic African savanna. During the two-year field study, we measured plant tolerance, resistance, and phenological traits, while comparing variation in leaf nitrogen and specific leaf area (SLA) across stands of Acacia nigrescens, Miller, that had […]
