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 Extravaganza

2011-09-14

Once again, Kovsies will showcase its most talented students at the Sand du Plessis Theatre in the annual Kovsie Extravaganza on 21st and 22nd September 2011. With guest artists, Vusi ‘The Voice’ Mahlasela and Die Heuwels Fantasties, it promises to be a first-class production. Expect music styles as diverse as hip-hop and pantsula dancers, a student string quartet, jazz band, various vocal groups and the winners of the campus serenade competition.

While it will certainly be a night to remember, this year will also benefit a cause you will find hard to forget. R25 of every ticket sold will go towards the No Student Hungry campaign (NSH), currently feeding just over a hundred Kovsie students on a daily basis. This means that the donation from each ticket bought will effectively buy one student food for one day.

Hunger on the Kovsie campus is an invisible problem that few ever consider, yet it affects an estimated 10% of the 31 000 students at Kovsies. ‘The problem with hunger at a learning institution is that it hampers talent. A hungry person can never achieve their full potential,’ says Grace Jansen, patroness of NSH.

To help alleviate this situation, you can buy a ticket for R75 at the PACOFS ticket office and join us on the 21st or 22nd September at the Sand du Plessis Theatre. Not only will it be a great night out, but you'll be doing your bit to invest in talent. Watch the press over the next two weeks for more information on this initiative.
