All mountains around the world have native and non-native species that are expanding their ranges quite dramatically; however, little research has been conducted towards understanding the long-term redistribution of species and the effects of global change on biodiversity.


The Afromontane Research Unit (ARU) on the University of the Free State Qwaqwa Campus – as part of the Mountain Invasion Research Network – has secured a two-year EU Horizon 2020 project under the Department of Science and Innovation, which will be looking at the mechanisms underlying the success and impact of range-expanding species on biodiversity and ecosystem functioning.

On Monday 19 July 2021, the ARU took a few of its researchers on a scenic helicopter ride to the summit of the Drakensberg for an alpine field-experiment site inspection of the Mont-aux-Sources peak, one of the highest sections of the Drakensberg range. This site has been identified for the project which the research unit will be leading on mountain research.

ARU Director, Dr Ralph Clark, said the project would explore the effects of global change, biological invasions (when species invade new geographic regions), as well as climate and land-use change. He said experiments were needed to explore the various possibilities and to test the extent to which species respond to experimental treatments. The project would therefore be conducting experiments for two years using open-top chambers – causing an increase in temperature of 3 or 4 degrees to what you find naturally – on plant species from lower down to the top of the mountain, to see how they function. “This will give us an idea of whether they will be able to survive in global warming scenarios. If temperatures get warmer, we might start seeing a lot of plants up here that we wouldn’t otherwise find here.”

Dr Clark said little is known about the long-term monitoring of species distribution and the effects of global change. Implementing the project in the Maloti-Drakensberg alpine area will therefore put the area in the global mountain research arena. The elevational gradient in the Maloti-Drakensberg Mountains provides space to explore the key processes underlying the variation in species elevation with climate change. “One of the things we don’t know much about are alpine systems. We are hoping to establish a long-term alpine research site and try to add as many studies as we can. The more science we can bring up here, the more we can know about mountain life. What happens on mountains has a lot of impact on social dynamics.

“This project is looking to see what is driving range expansion. Every mountain has its own context. In the Swiss alpine, fires are not a big factor, but fires are one of the biggest factors on our mountains. Some of our native and non-native species are therefore fire-driven, so as fire increases, you might have them spreading faster.”

An extension to the Department of Physics at the University of the Free State (UFS) was officially opened on the Bloemfontein Campus on 20 April 2016.

“This started off about five years ago when we were talking about not having enough room for large classes. Prof Matie Hoffman suggested that we build a large lecture room on our parking space,” said Prof Hendrik Swart, Professor in the Department of Physics as he addressed guests at the official opening ceremony.

“A year later, we received a Sarchi Research Chair [South African Research Chairs Initiative] on Advanced and Luminescent Materials. We needed more office and laboratory space. The two ideas were combined and presented to the university’s senior management,” he added.

When the university was founded in 1904, Prof James Lyle was appointed to head up the Physics and Chemistry departments. Five years later, a single room was allocated for the Physics laboratory in the main building upon its completion. In 1947, the old Physics building was designed and constructed. Fast forward 69 years, the department has reached another milestone. Facilities accommodated by the expansion include a new telescope for astrophysics experiments, a basement for storing old equipment, as well as a sliding trap door which allows heavy goods to be elevated into the building from the ground floor. The telescope is one of the many unique features of the building given its capacity to expose graduate students to the basic techniques of radio astronomy, especially in light of the fact that the SKA (Square Kilometre Array) project which is in progress.

“Our department is extremely strong at this stage, and a bright future lies ahead,” said Prof Koos Terblans, the Head of Department. The opening also served to celebrate the 103 publications achieved by the department last year.

Dr Lis Lange, Vice-Rector: Academic is proud of the heights reached by the department to date. “The Department of Physics is undoubtedly one of the jewels in the crown of our university, and we are very proud of its developments. Universities are built on legacies, and they are also about change, which is what this department has been demonstrating.”

The expansions to the building with its top-class facilities, was constructed at a cost of R25 million – an infrastructure grant courtesy of the Department of Higher Education and Training.
