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.”

UFS academic appointed as team doctor for SA Olympic Team
2012-03-22

 

Dr Holtzhausen’s appointment reflects well on the quality of exercise and sports medicine presented at the university.
20 March 2012

Dr Louis Holtzhausen, Head of the university’s Department of Sports and Exercise Medicine, has been selected by the South African Sports Confederation and Olympic Committee (Sascoc) as team doctor for the more than 300 athletes that will represent South Africa at this year’s Olympic Games in London.

“This is definitely one of the most important highlights of my career, in which I’ve worked with professional athletes and top sporting people,” says Dr Holtzhausen, a recognised South African academic in Sports Medicine.

“It is not only an honour to be appointed as team doctor for the South African Olympic Team. It is also a privilege to represent the UFS. The fact that Sascoc approached me reflects well on the quality of exercise and sports medicine that we present here at the university,” says Dr Holtzhausen.

Dr Holtzhausen says he has already worked with some of the athletes in the Olympic Team. These include members of the South African boxing team, the hockey team, as well as track and field athletes that have been preparing for the Olympic Games at the university’s High Performance Unit.

There is, however, hard work ahead for Dr Holtzhausen. His work will start before the team leaves for London in July. “I have to ensure that all the athletes are healthy and that everyone’s immunisation programmes are up to date. We also have to ensure that no athlete takes banned substances,” he says.

During the Games, Dr Holtzhausen will keep an eye on the optimal functioning of every athlete. “Anything that could hamper them medically will be sorted – whether it’s a broken ankle or a cold,” he says.

He will also see to it that medical services are available during the competition. Immediate medical assistance will be available, especially at high contact sports like boxing.

Dr Holtzhausen has also been team doctor for Team South Africa at the All Africa Games, the biggest sporting event in Africa. He was recently appointed as a member of the International Committee and Coordinator for Africa of the worldwide Exercise is Medicine project. This project proposes that exercise be used in the prevention of chronic disease in the general population, as well as in the treatment of people with existing chronic diseases. Dr Holtzhausen is also an honorary member of the South African Sports Medicine Association (SASMA). This membership is awarded to members of the medical and scientific community who make significant contributions to the advancement of sports medicine.

Dr Holtzhausen is a member of the Vice-Chancellor’s Prestige Scholars Programme.
The goal with the Prestige Scholars Programme is to select no more than 100 of the most promising young scholars (typically holding lecturer status) and to make substantial investments in their development towards the professoriate. A tailored, intensive programme of support has been designed which combines international placement working alongside leading scholars in the discipline of the prestige scholar, with intensive mentorship and support from within the university.
