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.”

Mafikizolo and Francois van Coke to perform at Kovsie Extravaganza

2015-09-09

What better way is there to welcome spring than to invite beautiful voices into our backyard? The Arts and Culture office at the University of the Free State (UFS) presents the annual Kovsie Extravaganza, a major highlight on our entertainment calendar.

This year, the musical festival features Mafikizolo and Fracois van Coke as the main acts.

Mafikizolo is an award-winning South African Kwaito duo consisting of Theo Kgosinkwe and Nhlanhla Nciza. The group has accumulated statuettes at the South African Music Awards for Duo of the Year in 2004, 2007 and 2014. Moreover, they have recently released Best Of 2015 - their latest album.

Francois van Coke is also scheduled to indulge Alternate Rock fans with tracks from his newly-released solo debut album. Francois is the lead vocalist, songwriter and founding member of the South African rock bands Fokofpolisiekar and Van Coke Kartel.

The Extravaganza stage will also be shared by our very own UFS Choir, and various students showcasing their musical, dance, poetry and other talents.

Event details:

Date: Saturday 12 September 2015

Time: 19:00

Place: Kovsie Kerk, Bloemfontein Campus

Tickets are available at R120 for the general public and R80 for students. For more information, contact Tonderai Chiyindiko on 051 401 9349 or Chiyindikot@ufs.ac.za.
