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.”

Funding available for Research Master’s and Doctoral studies

2015-11-30

The University of the Free State (UFS) has announced the availability of tuition bursaries for full-time and part-time studies in 2016.

All research master’s and PhD students who register in 2016 will receive funding to cover their tuition fees. South African and international students are eligible to apply.

The total value of the funding is equivalent to the annual tuition fees applicable for students from the SADC region, while the tuition of international students will be covered for 33% of the value of their studies.

Funding is available for two years for master’s students, and three and four years respectively for full-time and part-time PhD students. Renewal of the funding will be dependent on the previous year’s academic progress. To qualify, students must meet all academic requirements of the UFS and must have been provisionally admitted to an academic programme.

The UFS also recently announced that final-year undergraduate students, as well as students from other universities, may apply and pay no application or registration fees for an Honours degree in 2016. Click here for more information about Honours studies in 2016.

The Postgraduate School in the Johannes Brill Building can provide more information about all the scholarships, bursaries as well as offer research training support available for postgraduate studies.

The deadline for applications for Honours bursaries was 30 November 2015. There is no deadline for master’s and PhD bursary applications, as postgraduate students can register for these qualifications throughout the year.

All postgraduate application enquires can be directed to Ms Joy Nogabe on +27(0)51 401 7161 or nogabesj@ufs.ac.za.
