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 Centenary celebrations come to an end

2005-02-03

OFFICIAL OPENING

The official opening of the UFS will take place on Friday 04 February 2005 at 09:00 in the Reitz Hall (Centenary Complex). Please note that this is a test and lecture free day. The Rector and Vice-Chancellor, Prof. Frederick Fourie will be the keynote speaker. Refreshments will be served at the Centenary Complex after the opening ceremony.

The historic Centenary photograph will be taken at 11:00 on the eastern side of the Red Square (CR Swart parking area). All staff members and students are invited to be part of this massive photograph.

Important

• There will be no parking allowed on the CR Swart parking area until 12:00 on Friday 04 February 2005, as a result of the photo session.

• All academic staff members are requested to wear academic dress on the day, seeing as staff members will depict the Centenary emblem on the photograph. Academic gowns may be collected from the Gown Store on Wednesday 02 - Thursday 03 February 2005 between 08:00 and 16:00. Gowns must be returned to the Gown Store after the photograph has been taken.

SERVICE OF DEVOTION

A special service of devotion will take place on Sunday 06 February 2005 at 18:00 for 18:30 in front of the Main Building on the Red Square. This is a special gathering of students, hosted by all the interdenominational groups on the UFS campus. The evening will be a celebration of praise, thanks and worship, followed by a message from Dr Wollie Grobler. The evening will conclude with song and fireworks.

Staff members and students are welcome to bring their friends and families to this special event.

Important

• Even though there will be chairs in front of the Main Building, staff members and students are requested to bring extra pillows and blankets to sit on.

• No persons or vehicles will be allowed on the eastern side of the Red Square or on the CR Swart parking area, due to the security requirements of the fireworks show.

• All members of the choir are invited to be part of the mass choir. Lyrics will be provided.

• All persons who attend this event are requested to bring a candle for the purpose of the mass choir.

• Special transportation arrangements will be made for all service workers to enable them to attend the service. If there is someone in your faculty, department or division who would like to make use of this service, please send an e-mail to Elize Rall (ralle.stg@mail.uovs.ac.za) no later than Tuesday 01 February 2005.

OTHER ACTIVITIES

• A reunion for all former SRC members of the UFS will take place on the campus, from 04 February to 06 February 2005. An interesting programme is being planned. For more information, please contact Nicolaas du Plessis on 084 955 0875.

• The annual Rag Procession will take place on Saturday 05 February 2005. For more information, contact the Rag Office at X 2718.
