Patterns of permit requests and issuance for regulated alien and invasive species in South Africa for the period 2015‐2018

open access: yesAfrican Journal of Ecology, Volume 58, Issue 3, Page 514-528, September 2020., 2020
Abstract Invasive species typically establish in areas outside their natural distribution through accidental introduction and accidental release or escape. Some species are introduced legally for economic and social benefits such as recreational hunting, the pet trade and research through established permitting processes driven by appropriate laws and ...

Evolution of ungulate mating systems: Integrating social and environmental factors

open access: yesEcology and Evolution, Volume 10, Issue 11, Page 5160-5178, June 2020., 2020
We provide a new approach to understanding mating systems in ungulates. We integrate both social and environmental factors in doing so. We develop a predictive model to help understand the evolution of these unique behaviors, which should help to direct future studies.

Dental functional morphology predicts the scaling of chewing rate in mammals [PDF]

open access: yes, 2018
How food intake and mastication scale to satisfy the metabolic needs of mammals has been the subject of considerable scientific debate. Existing theory suggests that the negative allometric scaling of metabolic rate with body mass is compensated by a ...

Foraging investment in a long‐lived herbivore and vulnerability to coursing and stalking predators

open access: yesEcology and Evolution, Volume 8, Issue 20, Page 10147-10155, October 2018., 2018
Foraging is necessary for herbivores to grow and reproduce, but foraging also causes tooth erosion, which shortens life span. How herbivores negotiate this trade‐off has been primarily explored in systems without large predators. When selecting prey, coursing and stalking carnivores exploit unique vulnerabilities that might arise from variable ...

Insights into the Middle Pleistocene fauna of South Africa: Zooarchaeology, stable isotopes and dating of Pniel 6

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 1120-1139, August 2025.
ABSTRACT The Florisian Land Mammal Age (FLMA; 773‐12 ka) is characterised by specialist, often extinct, grazing as well as wetland species, many of which are no longer present in the southern African interior. Middle Pleistocene FLMA faunal assemblages are rare, particularly those associated with artefacts, limiting reconstruction of environmental ...
