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.”

Protest actions planned for 12-14 March 2008

2008-03-13

Three protest actions will take place on the Main Campus of the University of the Free State (UFS) in Bloemfontein this week.

Although the interim court interdict granted to the UFS on 6 March 2008 is still in force, permission for the three protests was granted by the Mangaung Local Municipality and the court, in the presence of the university lawyer. Strict conditions have been set for these protest actions.

The UFS management respects the right to peaceful protest and also shares the sentiment of the protesters regarding the reprehensible Reitz video. However, strict conditions have been set for these protest actions as students are writing tests and the normal academic activities should not be disrupted.

Already the first picket protest took place today, Wednesday, 12 March 2008, by about 300 Satawu and Nehawu members. This was not a march and no memorandum was handed over.

On Thursday, 13 March 2008, Nehawu will again picket in front of the Main Building from 13:00 to 14:00. This event must be peaceful. This too is not a march and no memorandum will be handed over.

On Friday, 14 March 2008, a march of Cosatu and Nehawu will take place, starting in the city centre. The march will enter through the Nelson Mandela Drive gate and will enter the campus grounds.

However, it will be limited to the incoming lane of Chancellors Avenue from the Main Gate to the crossing with Alumni Avenue (in front of the Odeion building). Speeches will be made and a memorandum will be handed over.

It is expected that the march will reach the campus at approximately 10:00 and from then the Nelson Mandela Gate to the UFS will be closed for all traffic. The march must end by 14:00. The marchers will return to the city centre and may cause a traffic problem in Nelson Mandela Drive.

The South African Police Service (SAPS) and the UFS’s Protection Services Division will monitor all these actions. Staff, students and visitors to the campus are kindly requested to use alternative gates to the Nelson Mandela entrance on Friday. Academic activities will continue as normal this week.
