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.”

It’s Rag Time!

Kovsie Rag Community Service will start 2014 off with the well-known Rag festivities, with enthusiastic students already starting with float building in January. The theme for Rag CS 2014 is ‘Movies.’

As from 20 January, a cheerful atmosphere will be present at the Kovsie Rag farm, with senior and junior students working hard, while social cohesion is developing between them. Great entertainment will be part of these festivities, with the likes of DJ Euphonik and Adam performing on 31 January.
In the midst of all these activities, the annual ‘Chicken Run’ evening collections will take place on 21, 23 and 28 January, as well as the Ritsim sales in Bloemfontein and surrounding areas on 24-25 January.

The hard work will reach its peak with the judging of the floats on the morning of 1 February, after which the floats will depart at 09:00 for the first procession of the day. This route will end at Twin City Mall at 11:00, where 10 000 meals will be distributed to communities in Heidedal and Mangaung. Learners from Heidedal schools will entertain the public with their talents.

Our very popular family festival will already start at 16:00 with the opening of the gates at Chevrolet Park Cricket Stadium. Young and old will be entertained by well-known and vibrant artists, such as Robbie Wessels, Mango Groove, Zakes Bantwini, as well as a spectacular firework show. Come early to ensure a great spot on the grass.

The float winners will be announced at 17:00, whereafter the main procession of the day will depart from the Tempe robot in Nelson Mandela Drive at 18:00. The public can look forward to this ever popular procession through the streets of Bloemfontein, with decorated floats and students cradling collection tins proceeding to Chevrolet Park. The 2012/2013 UFS Rag queen, Mr Rag and their retinue will greet the public from the main float. Finalists for the 2013/2014 UFS Rag queen and Mr Rag titles, as well as drum majorettes, will also accompany the procession.

Do not miss out on this wonderful family festival – come early, bring your family and picnic blanket/chairs to ensure a great spot on the grass – a variety of refreshments will be on sale.

Tickets available from Computicket and entrance gates.

Tickets: R60 per person
R30 per child under 12

We would also like to make use of this opportunity to remind you of our vibrant 2013/2014 UFS Rag coronation ball, where the UFS Rag queen and Mr Rag CS for 2014 will be crowned on 14 February 2014 in the Callie Human Centre, UFS Campus.

Limited tickets will be available at R500 per couple and can be bought from the Rag Community Service office from 5 February 2014.
