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.”

Discourse on statues and symbols puts transformation questions in the spotlight
2015-04-12

 

Amid various protest actions against historical statues across the country over the last two weeks, the University of the Free State’s Institute for Reconciliation and Social Justice presented a three-day discussion session the past week about the role and place of statues, symbols and signs in the transformation attempts of universities.

During these lunchtime sessions, various speakers from different contexts had expressed their opinions about this issue that has become a focal point, not only for universities, but also for the country as a whole.

Thus speakers not only gave their opinions about whether there is a place in present-day South Africa for statues and symbols from colonial and apartheid-South Africa, but also highlighted the cultural-historical values and the more deep-seated issues and symbolism of the statue-debate.

UFS Rector and Vice-Chancellor, Prof Jonathan Jansen, said on the first day of the session that the discourse was not about only one person’s memories, but about everyone’s in the country. He proposed that similar sessions should be held at each university campus.

He also said that, instead of breaking down, people should learn to live together, and everyone should be involved for transformation to occur.

Speakers who served on the panel, included academics from the UFS and Stellenbosch University as well as representatives of the Student Representative Council and of historical and heritage foundations.
