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.”

UFS celebrates Kovsie Week

2009-08-21

The University of the Free State (UFS) will be celebrating Kovsie Week from 31 August to 4 September 2009. The week affords friends, colleagues and former colleagues of the UFS the opportunity to enjoy one another’s company and to experience what the university offers.

The programme is as follows:

On Monday, 31 August 2009, a star-gazing programme and lecture entitled “400 Years of Astronomy after Galileo” are presented by Prof. Matie Hoffman at the Boyden Observatory at 17:30 for 18:00. Attendance is free and bus transport will be available from the UFS Main Campus for the first 70 guests that respond. Reserved parking has been arranged with a security guard to look after the cars that are left on the campus.

On Tuesday, 1 September 2009, guests can attend the production by Pieter Venter entitled “Impi” for free in the Wynand Mouton Theatre at 14:30 for 15:00.

On Wednesday, 2 September 2009, an enjoyable morning in the company of Mr Derek de Bruyn from the National Museum is presented at the Centenary Complex of the UFS at 09:30 for 10:00. He will talk about the social life of Bloemfontein during the early 1900s and guests will be entertained by the Boere Orkes of Grey College Primary School under the direction of Santjie Louw. Attendance of this event is free.

On Thursday, 3 September 2009, at 19:00 for 19:30, a candle-light, sherry and soup evening with romantic piano music is presented at the UFS Centenary Complex by Prof. Nicol Viljoen from the UFS’s Department of Music. The programme includes, amongst others, 10 Lieder ohne worte (Felix Mendelssohn), as well as Ballade No. 1 (Fryderyk Chopin). Attendance of this event is also free.

The week will end with the Kovsie-Alumni Award Gala Dinner that will take place in the UFS Centenary Complex on Friday, 4 September 2009, at 18:30 for 19:00.
The cost per person for the dinner is R120. The Kovsie of the Year Award for alumni, the Cum Laude Award, and the Alumni Award for Exceptional Service at the UFS will be awarded at this occasion.

Transport can be arranged to all the functions and parking will be available as close as possible to the venue where the functions take place. Persons interested to attend any of the functions can contact Annanda Calitz at 051 401 3382 or ficka.stg@ufs.ac.za, or Ms Kathy Verwey at 051 401 9343 or verweyke.stg@ufs.ac.za.
