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.”

New SRC elected on UFS main campus

2006-08-23

Ms Loraine Kriek, third-year student in B Consumer Sciences, was elected as SRC President of the Main Campus of the University of the Free State (UFS) for 2006/2007. Ms Kriek was a member of the Student Parliament in 2005/2006.

The most students in the history of the UFS – 6 353 in total – voted in this year’s election. There were only 44 spoiled votes. Last year 4 846 students voted.

“Other than last year, minor incidences of vandalism occurred on the Main Campus by students who were unhappy with the outcome,” said Dr Natie Luyt, Dean: Student Affairs at the UFS. According to Dr Luyt minor damage was caused to the Thakaneng Bridge and some other buildings on the Main Campus.

Kovsie Alliance obtained no proportional representation on the SRC, SASCO obtain 3 seats and the FF+Kovsies obtained 6 seats.

This representation gave Kovsie Alliance 1 seat, SASCO 14 seats and the FF+Kovsies 25 seats in the Student Parliament, which consists of 40 seats.

Nine of the 18 SRC members were directly elected and nine on the basis of proportional representation (PR). The PR system was introduced after amendments to the constitution of the Main Campus SRC were approved by the UFS Council in June 2005.

According to Dr Luyt elections on the Vista Campus will take place today (Wednesday 23 August 2006) and Thursday 24 August 2006. The results will be announced on Friday 25 August 2006. The SRC of the Qwaqwa Campus will be elected on Friday 25 August 2006. If there are no objections to the final results, it will be announced that same day.

The Central SRC, made up of representatives of the 3 campus SRCs, will be announced towards the end of September 2006.
