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.”

Odeion String Quartet nominated for KykNet Fiesta Award

The Odeion String Quartet at the University of the Free State has a chance of winning a KykNet Fiesta award for the ‘Best Achievement in Classical Music’.

The Odeion String Quartet was nominated for this category in January and the winners will be announced at a swanky gala night in Sea Point, Cape Town, on 5 March 2015. Other artists nominated in the same category, include Magdalena Minnaar (singer), Elizabeth Frandsen (singer) and the composer, Braam du Toit.

The latter were all part of the Poskantoor opera production at Aardklop. Artists are nominated on the basis of successful and award-winning performances at national arts festivals.

During the 2014 KKNK, the Odeion String Quartet won a Kanna award “for the best Classical Music production, Homage, where we honoured local classical composers in the light of South Africa’s 20-year celebrations,” says Prof Anmari van der Westhuizen Joubert of the Odeion String Quartet.

“We were requested to pay homage to a variety of composers in the production, namely Mokala Koapeng; Pieter de Villiers; Allan Stephenson and Hendrik Hofmeyr. The guest artist at the festival was the singer Zanne Stapelberg.”

Another event where the Odeion String Quartet was honoured, was last year’s Vryfees. They received the award as Best Classical Debut Artist for their production Bits and Pieces. The quartet also received the UFS Alumni Ambassador award last year.
