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.”

Anonymous e-mail campaign

2008-03-14

Statement by Prof. Frederick Fourie, Rector and Vice-Chancellor of the University of the Free State (UFS)

A number of anonymous e-mails have been sent around the country the past couple of days creating a false impression about the situation on the Main Campus of the University of the Free State (UFS) in Bloemfontein.

In the e-mail reference is made to the morning of Tuesday, 4 March 2008 when incidents of intimidation by black students occurred on the Main Campus.

In the e-mail it is alleged that a white girl was attacked at the food court, her clothes ripped from her body, thrown off the Thakaneng Bridge (the university’s student centre) and that she had to run back to her residence. This is not true and if it was the case, the matter would have been reported and would have been addressed immediately.

Allegations of chaos and disorder on the Main Campus in Bloemfontein are also made in the e-mail. This is also untrue. Two peaceful protest marches, for which permission was granted, have already taken place yesterday and today (Thursday, 13 March 2008). These marches took place without any incidents.

I regard this as an anonymous campaign to whip up emotions, destabilise the campus and to instill fear among staff and students who are traumatised by the Reitz video and the repercussions thereof.

I urge parents, especially, not to allow themselves to be upset by such false rumours and e-mails.

All the university’s community, including parents, staff and students must come to terms with the Reitz video in a calm and rational way. The UFS management is intensively busy to manage this situation in the interest of the university and all its people. Academic activities are continuing as normal.
