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.”

Kovsies welcomes first-years into the fold

Few life experiences are as exciting as becoming part of a university. On Friday 16 January 2015, Kovsies embraced our first-year students into our family after great anticipation.

That evening, first-years and their parents streamed to the Red Square on our Bloemfontein Campus where they were formally welcomed. This event also served to kick off the 2015 Gateway Programme – an orientation programme for all our first-years.

Dr Choice Makhetha, Vice-Rector: External Relations, addressed the first-years and congratulated them on their excellent matric results.

“The fact that you are here is a testimony to the level you are able to work at,” Dr Makhetha said.“You will have fun and make friends at the UFS. Your friends will be from different backgrounds and speak different languages than you. Embrace it all. You are now a part of the UFS family.

President of the Student Representative Council (SRC), Mosa Leteane, also reassured first-years that they are where they belong – at a university that inspires excellence.“This is the only space where the university’s international relations give opportunity to first-years to travel abroad with our F1 Leadership for Change Programme,” Leteane said. “It is the only space where the rector openly talks to his students, without having an appointment. It is the only space in our country where no student goes hungry due to our No Student Hungry (NSH) Programme.”

The following evening provided a spectacular live show with well-known artists Karen Zoid and Vusi Mahlasela entertaining the crowd. They performed alongside the Free State Symphony Orchestra (FSSO) that added even more dazzle to this Gateway/NSH first-years concert.

On Saturday 17 January, the new-comers had an opportunity to visit their respective faculties and get to know the staff and facilities a bit better.
