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.”

Kovsie Face of Facebook – the search is on

2014-04-07

Victor Ngubeni, our first Face of Facebook winner, 2013/2014

Our sensational Kovsie Face of Facebook competition is about to launch into its second year.

This is a golden opportunity for students who want to be a regular in front of the camera. As the winner, you will present videos for our UFS Facebook and YouTube pages.

How to enter
You need to complete an entry form, which you can download from [KovsieLife] or [Blackboard]. You can also pick up an entry form at the reception desk in the Student Life Centre (SRC Building).

Download Entry form

Submit your completed entry form at the reception desk mentioned above before 10:00 on Friday 11 April 2014.

Auditions
You will need to tell us in a minute, on video, why you should be our next Face of Facebook. Dress creatively, bring along props or posters and let your personality shine through.

The details for the auditions are:

Date: Tuesday 15 April 2014
Time: 08:30 – 13:00 and 14:00 – 16:30
Place: Bloemfontein Campus, North Block (of the Main Building), ground floor

Voting
The top ten videos will be loaded onto our UFS Facebook page. The public can then vote for their favourite by ‘liking’ the video. Remember, only those who have ‘liked’ the UFS Facebook page will be able to vote.

After voting ends, the person with the most ‘likes’ will be the winner and serve as our 2014/15 Face of Facebook.

Now, get those entries in!
