ARU pioneering mountain range-expanding project

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.”

Kovsie fencers dominate the Free State Fencing Closed Competition

Willem Brink and Wanda Verster fenced their hearts out at Free State Closed Competition, winning gold medals in the men’s and women’s category, respectively. These University of the Free State students dominated opponents from the Vrystaat Amateur Skerm Klub (VASK).

Fencers from the VASK retaliated bravely in defense of their honour on Saturday 12 September 2015, with Jurgen Schroder taking home a Silver medal. His team mates, Ruan Coetzee-Schroder and Shaeffer Georgiou, shared the Bronze medal. A winning performance placed VASK’s Danielle Ceronio and Stella Heyns in the Bronze realm. Kovsie Fencing’s Kayla de Gouveid shared the spot with Stella as a bronze recipient.

It was a clash of the titans as 27 participants formed opposing teams. The University of the Free State (UFS) team, who hosted the competition, showed the guests no sign of mercy as they triumphed.

Wanda was impressed by the UFS’s performance. “The students performed very well, especially considering that most of them started fencing just this year.”

“Willem Brink, who finished with gold, started fencing in 2012. He finished with a Bronze medal at the Free State Closed competition held earlier, in May 2015 The first fencer to reach 15 wins,” said the Kovsie Fencing representative.

The club will represent our university at the University of Pretoria (TUKS) Open where fencers from the entire country will compete on 25 and 26 September 2015. The club is also preparing for the University Sports South Africa (USSA) tournament and the Limpopo Open that take place in November and December, respectively. These competitions serve to pave the way for the July 2016 nationals, where Kovsies hope to make their mark as champions.
