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.”

International ties for OSM

2013-08-21

Prof Nicol Viljoen in the historic Teatr Zdrojowy in Walbrzych, Poland
20 August 2013

Profs Nicol and Martina Viljoen from the Odeion School of Music (OSM) recently undertook a very successful trip to Europe where Prof Nicol Viljoen rendered two solo piano recitals in Poland. They also delivered a joint paper at a congress in Budapest.

The first of the two recitals were held in Crakow at the famed Zespol Panstwowych School of Music. At this event, Prof Viljoen essentially recited Chopin Mazurkas and was invited to repeat this performance in Poland in the future.

The second piano recital was in the historicTeatr Zdrojowy im. Henryka Wieniawskiego in Walbrzych. This concert included Preludes, Mazurkas, as well as the Ballad in G minor by Chopin. After the Mazurkas, the audience rewarded Prof Viljoen with a standing ovasion – and again at the end of the concert. As a result of this, the chief organiser of the event, Jerzy Kosek, who is also the conductor of the Filharmonia Sudecka, invited Prof Viljoen to perform as soloist with his orchestra next year.

Kosek also invited Conducting students at the OSM to work with the Filharmonia under his leadership on an exchange basis. He indicated that he would like to strengthen the ties with the University of the Free State and the Odeion School of Music. Two members of the Filharmonia Sudecka are currently doctoral students in Performing Arts at the OSM, namely Karol Legierski (concertmaster) and Marianne Cilliers (first violin), while the co-concertmaster, Dorota Graca, is in the process of registering for doctoral studies at the OSM.

The paper delivered by Profs Viljoen in Budapest, formed part of the interdisciplinary congress, ‘The Arts in Society,’ where more than twenty countries were represented. Their paper dealt with the post-apartheid oeuvre of the South African composer, Hans Huyssen. Charla Schutte, another doctoral student at the OSM, delivered a paper on an interpretation of indoctrination songs on the basis of an analytical model by the philosopher Johann Visagie.

During the trip, Prof Martina Viljoen also had a productive meeting with the executive manager of Common Ground Publishers, an academic publisher based in the USA, with a view to publish work from the OSM.
