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.”

Former Kovsie wins Absa L’Atelier

A former Kovsie has taken top honours at the Absa L’Atelier Art Competition.

Elrie Joubert, who completed her master’s degree at the Department of Fine Arts in 2010, is the first Free Stater who has won the competition for young artists between 21 and 35. This puts her in the company of previous winners such as Penny Siopis and Diane Victor. As the overall winner, Joubert receives a cash prize of R110 000 and a six month stay at the Cité Internationale des Arts in Paris, France.

Her winning entry, Selective Unveiling, consists of a light-table with a private collection of miniature natural objects, a digital microscope used by the viewer to inspect the objects, as well as a projector that projects the microscope’s image directly on a screen.

“By making my private collection public, I expose myself to possible investigation and criticism,” says Joubert about her winning entry. “The process is, however, reversed when the viewer is also robbed of his/her ‘privacy’ in collecting images with the microscope, which are projected on a screen for other viewers to see.”

Joubert, who lectures in Drawing and History of Art of Graphic Design at the Midrand Graduate Institute’s Bloemfontein Campus, says the Absa L’Atelier is the biggest competition she has won thus far. In 2007 and 2010 she reached the final rounds of the SASOL New Signatures Art Competition.

Her advice to art students: “Keep on doing what you do, learn to handle criticism selectively, and above all, if you take no risks you’ll never win.”
