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.”

2015 RAG promises family fun

2015-01-30

The annual Kovsie Rag Community Service (CS) procession will take place on Saturday 31 January 2015 and this year’s theme is all about Video Games and City Icons.

The floats are judged on 31 January andwill depart at 09:00 from the UFS Bloemfontein Campus’ Furstenburg Gate (near Tempe) for the first procession of the day.

Their route will end at Twin City mall where 6 000 meals will be distributed to Heidedal and Mangaung communities.

The float winners will be announced at 17:00, just before the main procession of the day will again depart from Furstenberg Gate in Nelson Mandela Drive.The 2014 UFS Rag queen, Mr Rag and their runners-up will greet the public from the main float. Finalists for the 2015 UFS Rag queen and Mr Rag titles will also accompany the procession.

The popular family festival will take place at Chevrolet Park cricket stadium. There, young and old will be entertained by well-known artists such as K. O, Riana Nel and Matthew Mole.

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 are available from Computicket as well as at the entrance gates.
Tickets: R80 per person
R50 per child under 12
