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.”

Mpofu-Walsh inspires with music, word, and wisdom

“Sometimes it’s the parts of us that give us the most agony, the parts of us that we think we need to change to conform to other people’s expectations, which are actually the gateways which allow us to make an impact in the world.”

This encouragement from Sizwe Mpofu-Walsh was one of the highlights of the 2017 TEDxUFS conference. According to the author, musician, and activist, we should embrace every part of ourselves. We should understand that the way in which each of us can change the world, is by becoming one with all the different parts of us which people think can’t come together.

Audience hears project for first time

For the first time ever, Sizwe shared material from his project Democracy and delusionwith an audience at the 4th annual TEDxUFS conference in the Odeion Theatre at the University of the Free State on 5 August 2017. Other speakers included the likes of Murendeni Mafumo, founder of Gentle Giant, and Elijah Djan, CEO and inventor of Nubrix.

The event also included TEDx videos, breath-taking performances, and cutting-edge technological exhibitions. The theme was Prism of Possibilities.

Launching a book and album together

Sizwe shared how he, while studying at the University of Oxford, embarked on an ambitious project where he combined his passion for academics and music: To release a book and album about the same things at the same time.

The project is a reflection of the political landscape in South Africa. Sizwe showed how he created a song about student protests by putting different layers of music together.

“The only way to do something that will leave you truly remembered is to do something different. It is to take all of yourself and pour it into the creative pursuit that you produce.”
