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.”

UFS community makes difference through Big Give Project

Thanks to the caring community of the University of the Free State (UFS), students in need were provided for during exams, and will receive more food in the cold winter months.

Once again, staff and students made valuable contributions at the successful RAG Big Give Project, where food contributions of R 38 176.20 and cash donations of R25 000 were received. Staff, residences, and the RAG Committee made these donations as part of the project on 5 May 2016, when contributions were made at the Bloemfontein Campus gates of the UFS. An extra donation by Imperium, a residence on the Bloemfontein Campus, of R20 000 for FutureLife helped to achieve the grand total of food contributions.

According to Vicky Simpson, Assistant Officer at the No Student Hungry Food Bursary Programme (NSH), the food donation is for a designated group of students who have already been identified as food insecure by the social work office. “It will be distributed to them on a monthly basis,” she said.

The handover of food collected was done on 25 May 2016 at the RAG Food store by the RAG Office to Health and Wellness and the NSH. The RAG Office thanked the UFS community for its contributions to the project. Parexel, who made cash and food donations, received special mention. Simpson said “the food will make a huge difference in the lives of students who do not know where their next meal will come from”.

According to Jaco Faul, Senior Assistant Officer Rag CS, his office is already looking forward to the next instalment of the Big Give Project. “We challenge faculties and staff members for the forthcoming Rag Big Give project in October to see if we can beat the amount collected this time.”
