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.”

PSP allows Dr Thom Wium to develop as an academic
2016-12-26

Description: Matildie PSP Tags: Matildie PSP 

For Dr Matildie Thom Wium, the
rewarding part of teaching is “the
moments of synergy with a group of
students” and when she senses that she
could, for instance, help them to better
understand a music selection.

Being part of the Vice-Chancellor’s Prestige Scholars Programme (PSP) has opened doors for Dr Matildie Thom Wium. She is able to better plan her research, and the overseas trips she has to undertake for this helps to develop her skills.

The senior lecturer in the Odeion School of Music (OSM) at the University of the Free State (UFS) says these are some of the advantages the PSP holds for her.

She attended two international conferences this year – in London in January, and in New York in August. Furthermore, she is working on musical analysis with Prof Timothy Jackson at the University of North Texas, US from 12 September 2016 to 31 December 2016. Prof Jackson is a research professor and was one of her PhD promoters.

Conferences contribute to her vision
“I think the PSP is a fantastic initiative,” says Dr Thom Wium, whose husband Daniël Wium is a lecturer in Astrophysics at the UFS. She says the reseach support from the PSP is amazing. “In addition, the writing retreats offered by the PSP help to set time aside during the busy semester to work on articles.”

“I think the PSP is a fantastic initiative.”

The conference in London was on operatic practice in the 19th century. In the US, Dr Thom Wium, who has been working at the UFS since 2007, also participated in a panel discussion on this topic. “It means a lot for my vision as an academic to participate in conferences where I have the opportunity to meet and exchange thoughts with the people whose work I read and cite.”

Involvement in SA equally important

However, she believes that it is equally important to stay involved locally. At the conference of the South African Society for Research in Music, which was hosted by the OSM from 25 to 27 August 2016, she presented a paper on composer Arnold van Wyk and performed a song cycle by him. She did research on Van Wyk for her PhD.
