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.”

Mr Naka Drotské is Kovsie Alumnus of the Year

2006-03-03

Alumni of the University of the Free State (UFS) appointed Mr Naka Drotské as Kovsie Alumnus of the Year 2005.

The award is made to Mr Drotské for the professional way in which he led the Cheetah Rugby Team last year. This played a determining role in the team’s 2005 Currie Cup victory.

The Cum Laude Award, made from time to time to any alumnus for outstanding service or achievement at local, national or international level in his/her specific career domain, will be awarded to Mr Harold Verster (president of the Free State Rugby Union).

Mr Verster receives the award for the role he played in the inclusion of the Vodacom Cheetahs as Super 14 team, as well as for his leadership that contributed to the success of the Cheetah Rugby Team in 2005.

Prof Johan Henning, Dean: Faculty of Law at the UFS, receives the Kovsie Alumni National Management Award for Exceptional Service. This award is made from time to time to an individual who has rendered exceptional service to the UFS.

Prof Henning receives this award for his role in the expansion and development of the Faculty of Law as academic, centre head, department head and, especially, as dean.

The award ceremony will take place on Friday 10 March 2006 during a Gala Award Banquet in the Reitz Hall of the UFS Centenary Complex on the Main Campus in Bloemfontein.

All alumni of the UFS are welcome to attend the function. The guest artist is Matthys Roets and the entrance fee of R80 per person includes a three course meal.

Those who are interested can contact Ms Jeannette Boshoff-Jansen at (051) 401-3594 or alumni@mail.uovs.ac.za.
