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 artists to rock at Vryfees

2014-06-18

It is the dead of winter in the heart of the Free State. The Vryfees is laying full steam ahead.

However, the talent that makes of this annual arts festival such a phenomenal success doesn’t only come from outside of our Bloemfontein Campus. This year’s productions will abound with performances by Kovsie staff, students and alumni from our Department of Drama and Theatre Arts.

Behind the scenes, our people will also play a vital role in the achievement and progress of the festival. Prof Luwes is a member of the festival committee and together with Dr Venter and Godfrey Manenye, he also serves on the artistic selection committee for theatre.

Thys Heydenrych, lecturer in the above department, was appointed as the technical manager of this year’s Vryfees. This means that he is in charge of the placement and assigning of venues for productions on campus. All the technical aspects for these venues rest on Heydenrych’s shoulders. For this huge task, he is supported by a team of technical staff which includes mostly students.

Take a look at the list of all our Kovsie artists who are working hard to make the 2014 Vryfees better than ever:
