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.”

Chemistry gets substantial grants

10 June 2013

Three research groups in the Department of Chemistry received substantial grants to the value of R4,55 million. The funding includes bursaries for students and post-doctoral fellows, mobility grants, running costs and equipment support, as well as dedicated funds for two young scientists in the UFS Prestige Scholar Programme, Drs Lizette Erasmus and Alice Brink.

The funding comes from Sasol, the THRIP programme of the National Research Foundation (NRF) and PetLabs Pharmaceuticals for the overarching thrust in Organic Synthesis, Homogeneous and Heterogeneous Catalysis. The programme has a broad focuse on different fundamental and applied aspects of process chemistry. Research groups of Profs Andreas Roodt (Inorganic), Jannie Swarts (Physical) and Ben Bezuidenhoudt (Organic / Process), principal members of the focus area of (Green) Petrochemicals in the Materials and Nanosciences Strategic Research Cluster (MNS Cluster) will benefit from the grant.

This funding was granted based on the continued and high-level outputs by the groups, which resulted in more than 40 papers featuring in international chemistry publications in merely the past year. A few papers also appeared in the top experimental inorganic chemistry journal from the American Chemical Society, Inorganic Chemistry. These high-impact papers address important issues in catalysis under the UFS Material and Nanosciences Research Cluster initiative, as well as other aspects of fundamental chemistry, but with an applied approach and focus.

Prof Andreas Roodt, Distinguished Professor and Chairperson of the Department of Chemistry, said the grants will enable the three research groups to move forward in their respective research areas associated with petrochemicals and other projects, and enable additional students in the department to benefit from it. It will also ensure that these groups can continue and maintain their research on different molecular and nano-scale materials. Current experiments include conversions under extremely high gas pressures (typical 100 times that in motor car tyres). This takes place at the molecular level and at preselected nano-surfaces, to convert cheaper feed-stream starting materials into higher value-added products for use as special additives in gasoline and other speciality chemicals.

The funding support forms part of the Hub-and-Spoke initiative at Sasol under which certain universities and specifically the UFS Department of Chemistry have been identified for strategic support for research and development. The department and the UFS gratefully acknowledge this continued and generous support from all parties concerned.
