What impact has global change had on alpine vegetation in our own mountains and those around the world, and why are certain plants in mountains around the world rapidly expanding their ranges?

This is the question on which the Afromontane Research Unit (ARU) on the Qwaqwa Campus will be shining the research lens over the next three years, through Project ‘RangeX’, a multi-institutional research consortium under the Mountain Invasive Research Network (MIREN), with ETH Zurich (Switzerland) leading the research project. The project is underway in the Witsieshoek area of the Free State component of the Maloti-Drakensberg, as part of a global consortium to better understand the ecological drivers of range-expanding plant species in mountains around the world.

South Africa’s participation in the project is led by the ARU Director, Dr Ralph Clark. Other RangeX partners are Germany, Norway, Sweden, Denmark, Australia, China, Chile, and France, with research locations in the Swiss Alps, Himalayas, Andes, Australian Alps, and Scandes.

The official launch of the research site for the Maloti-Drakensberg mountains, which took place on 20 October, marked the beginning of the South African component of globally coordinated research to understand how range-expanding species may affect current alpine environments under future climatic conditions. The launch involved a site visit to the summit of the Maloti-Drakensberg. Situated at 3 100 m above sea level in the Witsieshoek area, the research seeks to determine whether typical range-expanding species might colonise the alpine zone above 2 800 m under a simulated future warmer climate. 

The South African component of RangeX is funded by the Department of Science and Innovation (DSI) through BiodivERsA, an initiative of the European Union’s Horizon 2020, which promotes research on biodiversity and ecosystem services and offers innovative opportunities for the conservation and sustainable management of biodiversity.
Speaking at the launch of the project, Dr Clark said the alpine zone of the Maloti-Drakensberg is an ecologically severe environment, resulting in only specialised species being found above 2 800 m. “However, with climate warming, it can be expected that many lower elevation plants might start to ‘climb’ the mountain and invade its upper reaches. This will have a major impact on ecology, livelihoods, endemic alpine species, and water production.”

This is the first time that such experiments will be undertaken in the alpine context of the Maloti-Drakensberg, Dr Clark explained. The ARU is using this project to promote an ambitious and long-term alpine research programme centred on the Mont-aux-Sources area, where the Free State, KwaZulu-Natal, and Lesotho meet.  

Toto Matshediso, Deputy Director: Strategic Partnerships at DSI, said the Range X project with South African funding from the DSI was aligned with the departmental priorities for investment in global change and biodiversity research and innovation. 

“The research conducted is strengthening international cooperation in terms of research collaboration with its European Union partners as a region, as well as bilateral partners involved in the project. The project is also located in an area that has been historically disadvantaged, and the DSI is proud to be part of contributors to mountain research initiatives and direct contribution to the local community. The project also places the spotlight on the rich biodiversity data of the area, and how it could contribute to the overall government priorities regarding biodiversity.”

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
