Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna
Journal of Ecology, Volume 111, Issue 1, Page 33-44, January 2023., 2023 Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions.

A morphometric and genetic investigation of Opuntia engelmannii population variation in Africa
Weed Research, Volume 62, Issue 5, Page 307-317, October 2022., 2022 Abstract Opuntia engelmannii Salm‐Dyck (Cactaceae:Opuntioideae) is a morphologically variable cactus that has invaded pasture lands in South Africa and Kenya. Biological control of invasive Opuntia species can be very successful when the correct agent is matched with the appropriate host.

We and herbivores eat endophytes
Microbial Biotechnology, Volume 14, Issue 4, Page 1282-1299, July 2021., 2021 Here a cycle of endophytic‐enteric‐soil‐endophytic microbes is proposed which has relevance for health and comprises the fate of animal faeces as natural microbial inoculants for plants that constitute bacterial sources for animal guts. Summary Health depends on the diet and a vegetal diet promotes health by providing fibres, vitamins and diverse ...

Equity in ecosystem restoration
Restoration Ecology, Volume 29, Issue 5, July 2021., 2021 The importance of equity has been emphasized in climate change, biodiversity loss, land degradation, and ecosystem restoration. However, equity implications are rarely considered explicitly in restoration projects. Although the role of equity has been studied in the context of biodiversity conservation and environmental governance, environmental ...

Automatic Guided Vehicle that detects Dactylopius Opuntiae in Cactus Pears
Journal of Physics: Conference Series, 2020 Abstract Food security is one of the biggest challenges faced in Africa with drought being one of the leading factors. Cactus pear is a drought-resistant source of food for both animals and humans. They have become indigenous in South Africa and has maintained a role in the diet of the local population and animal feed.
