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.”

Livestream of Graduation Ceremonies

Six days, eleven ceremonies, and more than 5 000 degrees. This all forms part of what is the biggest set of graduation ceremonies in the history of the University of the Free State (UFS).

The mid-year graduation ceremonies, taking place from 19 to 26 June 2017 in the Callie Human Centre on the Bloemfontein Campus, will see the most students graduate during a week. A total of 5 258 degrees, which includes 460 master’s and doctoral degrees, will be conferred – including 72 doctoral degrees.

First graduation ceremonies for Prof Petersen
It will also be the first ceremonies that Prof Francis Petersen, new Rector and Vice-Chancellor, attends on the Bloemfontein Campus. Students from all seven faculties, as well as the South Campus, will graduate.

Graduates per faculty are (without master’s and doctoral degrees): Faculty of Education (488), Faculty of Health Sciences (345), Faculty of Theology (29), Faculty of Law (686), Faculty of Natural and Agricultural Sciences (1 029), Faculty of Economic and Management Sciences (1 044), Faculty of the Humanities (826), and the South Campus (354).

Guest speakers include three judges
Guest speakers for the ceremonies include Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, Dr Susan Vosloo, UFS Council member and founder member of the World Society for Paediatric and Congenital Heart Surgery, and Prof Petersen.

Three judges will also act as speakers. They are Justice Ian van der Merwe, Judge of Appeal at the Supreme Court of Appeal and former Chair of the UFS Council, Justice Mahube Molemela, Judge President of the Free State Division of the High Court and Acting Justice of the Supreme Court of South Africa, and Justice Connie Mocumie, Judge of Appeal at the Supreme Court of Appeal.
