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.”

New champions crowned at first-year athletics

The University of the Free State’s first-year athletics is an institution. It is a day marked by colour, spirit, and hoarse voices, but in 2017 produced something different than the last couple of years.

For the first time in four years, new athletics champions were crowned in both the men’s and women’s sections when Veritas and Sonnedou walked away with the trophies at Pellies Park on the Bloemfontein Campus on 25 January 2017.

Wag-’n-Bietjie, Vishuis relinquish titles

Sonnedou, who came second in 2016, broke Wag-’n-Bietjie’s stronghold of the past six years by winning the women’s athletics trophy. Furthermore, Sonnedou won this trophy more than a decade ago – in 2004. Veritas, who won the men’s athletics trophy for the first time since 2011, also put a stop to Vishuis’s dominance. House Abraham Fischer has worn the athletics crown for the past three years.

This year, Vishuis (70 points) took second place after Veritas (76), with Armentum (61) third. Sonnedou (99 points) easily triumphed in the women’s division, while Akasia (36) and Wag-?-Bietjie (34) respectively took second and third place.

Veritas captures overall Spirit trophy

However, the event is about much more than the action on and around the athletics track. First-years also get the opportunity to show pride in their residences by shouting at the top of their lungs.

Veritas, better-known in recent years for its excellent sêr groups, asserted itself even more by being named as the overall winner of the Spirit trophy. This residence was also the winner of the men’s section. Harmony won the Spirit trophy for women’s residences, while Conlaurês was the co-ed residence with the greatest spirit.
