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.”

Armentum make their mark on Barefoot Day

2015-08-19

On a cloudy day when it seemed that no one would be willing to take off their shoes, Armentum men’s residence and Put Foot Foundation supporters stepped out in their numbers to provide shoes for less fortunate school children.

With a R10 donation, supporters could dip their feet in paint in order to make their mark on the blank canvas in support of this good cause. The main aim of barefoot day is to tackle the daily plight and indignity of school children.

The Armentum students kicked off the event on the Red Square at the UFS Bloemfontein Campus, where they were partnered by the Institute for Reconciliation and Social Justice.

On the day, Dr Choice Mokgetha, Vice-Rector: External Relations, and Prof Nicky Morgan, Vice-Rector: Operations, made a contribution of R1000 for all the foot prints made on the canvas.

“The idea was conceived by the residence and RC Culture, Thapelo Makhubalo. Joining hands with the Institute for Reconciliation and Social Justice made it possible for us to make it an even bigger event. “Since I work at the Institute, and they work with human rights, it was easier to get them on board,” said the Prime of Armentum, Eddie de Wet.

At the end of the event, the blank canvas was filled with footprints supporting the initiative. All proceeds will be used to put shoes on the feet of children.
