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.”

Avant-garde filmmaker. Renowned feminist scholar. Revolutionary Prof Laura Mulvey.
2014-06-27

Prof Laura Mulvey – currently a professor at Film and Media Studies at Birkbeck, University of London, is about to visit the Bloemfontein Campus. As a tribute to her achievements, the UFS is bestowing an Honorary Doctorate on her during our Winter Graduation Ceremony. In addition, two events are scheduled during which the public can get to know Prof Mulvey and her films better.

Prof Mulvey is a hugely influential figure in the international arena of film and visual media. She is globally recognised as an eminent feminist film scholar and worked at the British Film Institute for many years. During the 1970s and ‘80s she exploded onto the scene as a prominent avant-garde filmmaker.

During her visit, she will discuss a film with Prof Annie van den Oever (University of Groningen) and some of her most renowned film material will also be screened.

Under the Skin of the City (Iran, 2001), directed by Rakhshan Bani-E'temad, will be screened in full on Thursday 3 July 2014. The film centres on the trials and tribulations faced by an Iranian family. This award-winning film will resonate with a South African audience because of the social issues it addresses. Prof Mulvey and Prof Van den Oever will also discuss the film afterwards.

On Saturday 5 July 2014, Prof Van den Oever and Prof Mulvey will have another discussion and the audience will be treated to snippets from her prominent films.

The details of these events are:

Date: Thursday 3 July 2014
Time: 16:00 – 18:15
Venue: CR Swart Auditorium, Bloemfontein Campus
RSVP: Elouise Johnsen, JohnsenE@ufs.ac.za, +27(0)51 401 2315 (mornings).
Refreshments will be served.

Date: Saturday 5 July 2014

Venue: CR Swart Auditorium, Bloemfontein Campus
RSVP: Elouise Johnsen, JohnsenE@ufs.ac.za, 27(0)51 401 2315 (mornings).
