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.”

UFS Camerata ends concert season on a high note

The OSM Camerata (OSMC) of the Odeion School of Music at the University of the Free State ended the 2017 concert season on a high note with two gala concerts presented in the Western Cape as part of the ensemble’s fifth birthday celebrations. The first concert took place at the well-known Hugo Lambrechts Auditorium in Parow on 20 October 2017. A Stellenbosch University audience also had the privilege of listening to the Camerata at Endler Hall the following day.

A substantial part of the concert programme recited during the concerts was dedicated to prolific South African composer, Prof Hendrik Hofmeyr, in honour of his 60th birthday on 20 November 2017. The ensemble recited Super Flumina Babylonis, Notturno Elegiaco & Spokewals/Phantom Waltz - all works commissioned from Prof Hofmeyr for the OSMC.

The Odeion School of Music awarded the Order of the OSM to Prof Hofmeyr during the concert in gratitude for his tremendous contribution as a South African composer.

The final concert at Endler Hall, presented by the Endler Concert Series, was attended by the UFS Rector and Vice-Chancellor, Prof Francis Petersen, and Mrs Cheslyn Petersen.

According to Marius Coetzee from the Odeion School of Music, the OSMC was strategically founded in 2012 as the OSM’s flagship chamber orchestra with its main objective being to create a catalyst for excellence. From a pedagogical perspective, the OSMC serves as an incubator to nurture fully rounded musicians who are thoroughly prepared for the demands of their trade as orchestral musicians, soloists and conductors.

Responding to the demand for excellence, on 1 September 2017 it was announced that the OSMC received first prize for the 2017 Ictus International Music Competition (US) as the winner of the category for Conservatory and University Orchestras.

Louis van der Watt, head of strings at the University of Stellenbosch Conservatory and vice conductor of the university’s symphony orchestra, remarked that the OSMC presented an excellent concert. Audience members concurred, saying the OSM Camerata was setting new standards for orchestral playing in South Africa.
