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.”

Bloemfontein’s Visser brothers to wow hometown fans

South Africa’s YouTube singing sensation, Vicus Visser, will wow Bloemfonteiners on 18 April 2013 with a musical performance at the University of the Free State.

He and his talented brother Vincent will perform at the Wynand Mouton Theatre giving their hometown fans a taste of their recent performances in the United States. Vicus, who has been dubbed Bloemfontein’s Justin Bieber, performed overseas for the first time in February this year when he and his brother performed at events for Black History Month in Washington DC and New York. One of their performances was at the Kennedy Centre in Washington DC where they paid tribute to Nelson Mandela and Martin Luther King.

Vicus rose to fame in 2010 when a music clip of him as a ten year old boy, singing “These Arms” by All for One, appeared on the internet. After a massive seven-year search on social media channels by local and international record companies, he was tracked down to Heidedal in Bloemfontein. Vicus and Vincent moved to Johannesburg in 2012 where they were managed and mentored by Gareth Cliff, top radio presenter and judge on Idols South Africa.

Gareth will join the Visser brothers in Bloemfontein on 18 April and will be master of ceremonies at the concert titled Singing the Dream for South Africa - The Kennedy Centre Performance. As with their performance in the United States, the brothers will treat the hometown crowd to a selection of songs in English, Zulu, Sesotho and Afrikaans.

Vicus, Vincent and Gareth will also make special appearances at the two graduation ceremonies hosted at 09:30 and 14:30 on 18 April 2013. Gareth will be guest speaker and the two brothers will give a short performance. They will also have a meet and greet session with students at the Thakaneng Bridge at 11:45.

Tickets for the Singing the Dream for South Africa - The Kennedy Centre Performance cost R 20 and are available at Room 5, Thakaneng Bridge. The show starts at 19:30.
