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.”

The University of the Free State (UFS) not only boasts a South African women’s cross-country champion, one of its women’s teams is also the best university team in the country.
The Kovsies 8 km women’s team was crowned the winners at the University Sports SA cross-country event in Richards Bay, while the 10 km men’s team finished second.

Kovsies men take second place

The women’s team consisted of Kesa Molotsane, Marne Mentz, and Lizandre Mulder. They respectively came in first, third and fifth at the USSA meeting held at the University of Zululand on 30 September and 1 October 2016. In the women’s competition, the times of the first three competitors are used to determine the team placements.

The UFS 4 km women’s team finished in 5th place.

The successful UFS 10 km men’s team consisted of four members from the Qwaqwa Campus – Lesedi Radebe (4th), Lebohang Miya (8th), Moorosi Semase (10th), and Lindobuhle Miya (11th). In the men’s competition, the times of the first four men in each team are taken into account.

The Kovsies 4 km men’s team finished sixth.

Molotsane’s dream year continues

Molotsane, assistant officer at KovsieSport, is experiencing a dream year. On 10 September 2016 she was crowned as national cross-country champion over 10 km when she represented the Free State in George. Mentz was third in George over 4 km.

Molotsane improved her own record in the 3 000 m at the Clover athletics meeting in Bloemfontein on 15 October 2016. Her time of 09:51.03 was much better than her previous record time of 10:03.97.

In the USSA road relay in Richards Bay on 1 October 2016, the Kovsies women’s team finished third in the 3 x 2 km relay. The men came fifth in the 4 x 4 km relay.
