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.”

Golden Key International Chapter again receives prestigious award for service

Our universities chapter of the Golden Key International Honours Society is the proud recipient of the Golden Key International Chapter Service Award for the second consecutive year.

The chapter received this $1000 award in recognition of the services they deliver to the community of the Free State and the hard work each of their members put in to ensure that their community projects run smoothly.

Mr Ruddy Banyini, the chapter president, says they feel very privileged to know that the chapter’s work receives international recognition. “We feel so privileged that the work of our chapter is appreciated internationally and that it will serve as motivation to everyone to start giving back to their communities,” he said.

The UFS chapter adopted The House of Compassion, an orphanage on the outskirts of Bloemfontein, at the start of 2010. They have collaborated with associations such as the PSA and visit the house on weekends to play with the children. They have also donated food, clothing and shoes. “Our chapter’s motto is ‘It’s not how happy we are that matters, but how happy others are because of us’” Mr Banyini said.

The chapter was selected as one of the 10 most deserving chapters from a possible 390 university and college chapters worldwide, based on their community-service activities. The chapter was also selected to host the South African Regional Golden Key Summit from 06 - 08 October 2011, which means that our university will host the top 15% of achievers from all South African universities.

Mr Banyini said this is a dream come true, since their chapter’s main goal is to see our university as South Africa’s Golden Key reference point.

The GK UFS Chapter will soon be starting a “Together means Warm” campaign which will attempt to provide winter clothes, shoes and new school shoes to the children of the orphanage and also improve their living condition.

“I would like to urge everybody to keep in mind that the community is everyone’s responsibility,” Mr Banyini said.
