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.”

Culture contributes to success of UFS rugby teams

The University of the Free State (UFS) Rugby Club has succeeded once again in creating a culture of values.

Marius van Rensburg, Chairman of the UFS Rugby Club, believes this was one of the reasons why Kovsies had so many rugby successes this year.

The UFS knows that money, which is more abundant at bigger universities, won't change the club into a rugby force, but "there is something special here," he said.

Van Rensburg added that the success of Shimlas, who won the Varsity Cup for the first time, also helped to build a winning culture.

Seven finals

Seven of the UFS Rugby Club's teams played in finals during 2015.

Shimlas beat the Pukke in the Varsity Cup final at Shimla Park on the Bloemfontein Campus.

The Kovsie Young Guns (against Tukkies) and Vishuis (Mopanie from Tukkies) got stuck in Bloemfontein in Varsity Cup finals.

The Shimlas won Section B of the USSA tournament in Johannesburg (against Madibaz in the final).

A strong Irawa rugby team beat Shimlas in the City Cup.

The Kovsie Sevens team was crowned as the Varsity Champions in Cape Town after beating Tukkies in the final. The team was beaten by Maties in the final of the USSA Sevens tournament in George.

Shimlas lays foundation

According to Van Rensburg, the Varsity Cup triumph by Shimlas laid a good foundation.

“After what happened in the Varsity Cup, the winning culture kind of washed over the other teams,” he said.

He also thinks the 2015 successes didn't happen overnight, but that the club managed to bring back good values. He feels that Franco Smith, the former Shimlas coach who is the Cheetahs’ current coach, also played an important part.

Greater pressure in 2016

In 2016, the UFS's rugby teams will have a greater target on their backs.

Van Rensburg agrees that there will be greater pressure, but the structures are in place.

He feels that Varsity Cup success goes together with a touch of luck, of which Shimlas had some this year.

“Looking at the draw, Shimlas will play their first two matches away against Ikeys and Tukkies. Therefore, after two matches, one might have no league points, and that would place the team under immediate pressure.”
