Most Porcelain crabs are tropical, so Prof George Branch was surprised to find a species he has never seen before under boulders in the cold waters of Saldanha Bay, a site he has sampled regularly over several decades.

a) Thermal patchiness among deep and shallow habitats on upper Berg River, b) a dead trout at a site on the Amandel River – presumably a result of thermal stress or low dissolved oxygen, c) isolated pools on the upper Amandel River during mid-summer 2017 – surface flow mostly disappeared, and d) a site on the Amandel River dried up in March 2017, leaving the temperature logger exposed to air (Photo credit: Jeremy Shelton)

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.
