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.”

Sibongile Potelwa, a postgraduate student at our university, has been nominated for the 2012 South African Traditional Music Achievement (SATMA) Award in the category “Best Praise Singer”.

Sibongile, who studies Financial Economics & Investment, has been a busy student on the Bloemfontein Campus, with a list of achievements that continues to grow. In his first year, he received a certificate for being on the list of the Top 10 First Years in academics at Villa Bravado residence and he was inducted as a member of the Golden Key International Honour Society in his second year. He was also a tutor in Accounting and Economics for first-year students. This year, Sibongile became a Student Ambassador for the university in the Office of the Rector.

Sibongile performs under the stage name “Sijadu” and has been involved in praise poetry since the age of 11. He lists his recent performance at the Charlotte Maxeke Memorial Lecture, where he performed in front of President Jacob Zuma and other cabinet ministers, as one of his favourites.

“I would like to appeal to the university community, the Free State Province and South Africa at large to vote for me. This award absolutely belongs to Kovsies and therefore I believe that we cannot let the opportunity pass us by,” says Sijadu.

The SATMA Awards take place on 27 October 2012 in East London in the Eastern Cape. Voting lines will be open until 26 October. People can vote by sending a sms with the following information: SATMA, SIJADU, BEST PRAISE SINGER to 34066. Each sms costs R2.
