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.”

Prof Oriel Thekisoe from the UFS was named recipient of the prestigious TW Kambule NRF-NSTF Award. The announcement was made during the 16th Annual NSTF-BHP Billiton 2013/2014 Awards Gala Dinner held in Johannesburg on Thursday 3 July 2014.

Prof Thekisoe is an Associate Professor in the university's Department of Zoology and Entomology at the Qwaqwa Campus.

He has been recognised as an emerging researcher for his outstanding contribution to Science, Engineering and Technology (SET).

"It is a great honour for the university to learn that Prof Thekisoe has won the award of the National Science and Technology Forum. This is a very competitive award and speaks of the quality and depth of talent at the UFS as we prepare the next generation of scientists and scholars,” said Vice-Chancellor and Rector of the UFS, Prof Jonathan Jansen.

"I hope that the award will inspire our current science students to work harder in pursuing the discovery of new methods and techniques which will improve our livelihoods,” Prof Thekisoe said after receiving the award from the Minister of Science and Technology, Ms Naledi Pandor. “I am grateful to the Dean of the Faculty of Natural and Agricultural Sciences, Prof Neil Heideman, for believing in me. I am also grateful to my former lecturers, Profs Peter Mbati, who is now the Rector of the University of Venda, and Noboru Inoue, from Japan’s Obihiro University, for grooming and inspiring the scientist in me.”

"Prof Thekisoe is at the forefront of the research development activities at the Qwaqwa Campus,” said Prof Corli Witthuhn, Vice-Rector: Research at the UFS. “He serves as a mentor to many of the younger scholars on the campus. As one of the Vice-Chancellor's Prestige Scholars at the university, he has the potential to become one of the most prominent researchers in his field in the country."

The Vice-Chancellor’s Prestige Programme (PSP) supports the accelerated scholarship of junior UFS researchers in the first five years after obtaining their PhDs. The prestige scholars participate in an intensive programme of support that includes international placement and intensive mentorship.
