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.”

UFS community proud of Wayde’s hat trick of awards

Wayde changed the game – Naidoo

For a long time, AB de Villiers and Chad le Clos have dominated fan support in South Africa, but Wayde van Niekerk changed the game.

This was what Kass Naidoo, well-known sports journalist and cricket commentator, tweeted after the Kovsie athlete, Wayde van Niekerk, made a clean sweep at the tenth SA Sports Awards in his home town, Bloemfontein, on Sunday 22 November 2015.

According to Naidoo, the golden boy from the University of the Free State (UFS) is now the hottest property in South Africa, and should be watched during the 2016 Olympic Games in Rio de Janeiro.

Hat trick for Kovsie athlete
Naidoo was one of several celebrities to congratulate Van Niekerk on Twitter after Wayde received a hat trick of awards in the Sand du Plessis Theatre. The 400 m athlete was named Sports Star of the Year, Sportsman of the Year, and was crowned as winner in the People’s Choice category.

Apart from this, a humble Van Niekerk received total prize money of R1,1 million and two luxury Mercedes Benz vehicles - one for Sports Star of the Year and one as People’s Choice winner.

Big names outperformed
What makes his awards even more remarkable is the fact that he has outperformed several big names.
In addition to De Villiers and Le Clos, the tennis player, Kevin Anderson, the swimmer, Cameron van der Burgh, and the athlete, Caroline Wöstmann, were all nominated for Sports Star of the Year.

For the People’s Choice Award, Van Niekerk beat De Villiers, the cyclist, Ashleigh Moolman-Pasio, (who was crowned Sportswoman of the Year), Le Clos, and the wheelchair tennis player, Lucas Sithole. The public voted for this award.

Le Clos was nominated with the mountain biker, Greg Minnaar, for Sportsman of the Year.

Best is yet to come
“I don't think we have seen the best of Wayde. Hopefully that will come in Rio next year, along with a gold medal,” Naidoo tweeted.

The Springbok winger, JP Pietersen, also congratulated Van Niekerk on the social network, saying that he deserved his award as Sportsman of the Year.
