Temperature influence impacts of invasive fish in Cape Fold Ecoregion’s rivers

A new study, led by C·I·B post-doctoral fellow Jeremy Shelton, has shown that water temperature plays a role in the impacts that an introduced fish has on native fishes.

Mobilising the next generation woman scientists

On 25 May 2018, a group of ten highly motivated Grade 11 girls, visited the C·I·B and the Department of Botany and Zoology to learn more about women in science. This event, which forms part of the annual Cell C Take a Girl Child initiative, gave the girls from Vusisizwe Secondary School in Worcester, the opportunity to interview a variety of women about their careers, the highlights and challenges that come with their jobs and why they chose these careers.

Impacts of feral mammals assessed using three frameworks

Feral mammals impact the recipient environments in various and often devastating ways. The finding was the result of a study by former C·I·B Hons student Bianca Hagen and C·I·B core team member Dr Sabrina Kumschick at Stellenbosch University. The study, which was published in NeoBiota, classified impacts using three scoring schemes.

Introduced rats and their co-introduced parasites

The helminth parasites harboured by invasive rodents in South Africa are closely related to geographically distant counterparts. This was revealed by research conducted on parasitic worms of the brown rat (Rattus norvegicus), the black rat (Rattus rattus) and the Asian house rat (Rattus tanezumi) in urban areas of Gauteng Province by C·I·B doctoral student, Rolanda Julius at the University of Pretoria.
