The South African Journal of Science is a multidisciplinary science journal published bimonthly by the Academy of Science of South Africa. Our mandate is to publish original research with an interdisciplinary or regional focus and to provide a forum for discussion of news and developments in research and higher education. About the cover: A brown hyena (Parahyaena brunnea). Brown hyenas are found in Angola, Botswana, Namibia, South Africa and Zimbabwe, with almost one-third of the global population occurring in Namibia. Ramello and colleagues describe the spatio-temporal behaviour of the brown hyena in the Fish River Canyon, Namibia. Other topics in this issue include: Status of wild rooibos and its ecotypes; Stone tools and knowledge sharing in the Stone Age; Research software: Key but neglected in digital research; and much more!
