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.”

Springbok call-up tops Rhule’s dream season

We can add yet another name to our already impressive list of Springbok rugby players. Raymond Rhule has been included by Heyneke Meyer as one of five uncapped players for the Springboks’ upcoming European tour.

The nod from the selectors caps a tremendous year for the Ghanaian-born star. The former Technical High School Louis Botha pupil and current UFS student rose through the South African rugby ranks at a rate which can only be described as spectacular.

He was part of the Shimla team which competed in this year’s under-20 and senior Varsity Cups that culminated in inclusion in the victorious South African team at the under-20 World Cup.

Since then, he has been a fixture in the Free State Cheetah team in both the Vodacom Cup and the premier local rugby competition, the ABSA Currie Cup, gaining praise for his performance from the public and rugby experts along the way.

The 19-year-old wing has been the stand-out performer for a troubled Free State Cheetahs outfit, who had to see off the Eastern Province Kings in relegation playoffs to stay in the top division of the ABSA Currie Cup.

In an impressive season, Rhule scored eight tries, earning him the spot as the competition’s top try scorer.

Among a raft of awards, Rhule was announced as the UFS Junior Sportsman of the year for 2012 in October and has been nominated as the South African Rugby Union’s (Saru) Young Player of the Year.
