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.”

Theatre, photography, literature, and lectures: TFR Studies to showcase their success

2016-11-29

The end of the year usually introduces a mood of reflection on what was and what could have been. For Trauma, Forgiveness and Reconciliation (TFR) Studies at the University of the Free State, the past year recalls a flourish of achievements worth celebrating.

Therefore, TFR Studies held an end-of-year event to showcase the successes of 2016. This comprised lectures from leading researchers in social sciences and housing rights, the release of three new books, a theatre production, and a photo exhibition.

Lectures
Prof Anthony Collins – a leading scholar in identity and culture – will speak about violence in contemporary South Africa. Prof Collins, who holds a PhD from the University of California, Santa Cruz, has extensive knowledge in the interdisciplinary area of critical social sciences and won two national awards for teaching and learning.

In addition, housing rights activist Faeza Meyer will share her experiences of forced eviction and violence in Kapteinsklip, Western Cape. She will also talk about the process of documenting these experiences and working together with feminist historian Koni Benson.

New books
Breathe in the smell of fresh ink as Dr Samantha van Schalkwyk, Dr Kim Wale, and PhD candidate Naleli Morojele introduce their books to the public. Themes of violence and gender – pertinent to South Africa – thread through each of these books in unique ways.

Theatre
The award-winning play, AVU – directed and produced by Michelle Hoffman who is a master’s student at TFR – will be performed. The story dances between the blurry lines of reality and fantasy, between Boer and Bantu.

Photo exhibition
Lerato Machetela, a PhD candidate with TFR, has featured as one of SA’s Heroes for her work among the youth of Jagersfontein. Through an innovative method, Machetela is employing an arts-based approach to research through PhotoVoice. The result: a photo exhibition by the youth of Jagersfontein – and a rare opportunity to see the world through the eyes of a child.
