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.”

Well-known radio personality and Idols South Africa judge, Gareth Cliff addressed graduates on the third day of the University of the Free State (UFS) Autumn Graduation Ceremony.

“It’s a good time be alive, a good time to be a South African, a good time to be a qualified South African,” Gareth said during the graduation ceremony of the Faculty of Natural and Agricultural Sciences.

He emphasised the importance of skills in science in South Africa nowadays. “The only way we can advance is through an education of our minds, through technology, through science, through maths. It’s a time in our country’s development that we require minds such as yours to propel us forward.”

Gareth also underlined the freedom of speech in South Africa, especially in the light of media freedom. “It is something I feel strongly about, something this generation takes for granted.”

Dr Khotso Mokhele, Chancellor of the university, reinforced Gareth’s message and said that graduates need to be able to take standpoint against issues.

Learners from schools in Thaba Nchu and Botshabelo also had the opportunity to attend the ceremony.

The Autumn Graduation Ceremony takes place until Friday 19 April 2013. Attached is the programme for this ceremony.

Friday 19 April 2013

09:30 Diplomas and certificates up to and including honours degrees in the Faculty of Economic and Management Sciences: all diplomas and degrees in the Faculty, except BCom and BComHons.
14:30 Diplomas and certificates up to and including honours degrees in the Faculty of Economic and Management Sciences: only BCom and BComHons.

The Qwaqwa Campus’ graduation ceremony will take place on 8 June 2013. Diplomas / certificates up to and including doctorates will be awarded at this ceremony.
