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.”

Right to Learn cyclists still solid on the pedals

It is a new day and the Right to Learn cycling team continues to make its way to Cape Town.The team arrived at their first stop in Luckhoff on day one, after cycling for 182 kilometres in five hours and five minutes. They left Luckhoff at 05:00 in the morning on day two, heading towards Britstown via De Aar and arrived at midday. On day three, the team will rest in Britstown and will continue cycling on day four, 30 November 2017, to Victoria West for 133 kilometres via Merriman.

Looking forward to another day
Asive Dlanjwa, Bloemfontein Campus SRC President, felt confident about day two despite the strong winds that they experienced along the way. “I’m feeling strong, I actually thought after day one that I’ll be feeling a bit weak, but I just don’t know how we are going to make it in this wind,” he says. Dlanjwa and his fellow cyclists cycled for 213 kilometres to Britstown, where they ended their race for day two.

Kovsies fully behind cycling team
The tour began on 27 November 2017 in Bloemfontein, when they were sent off by Prof Nicky Morgan, former Vice-Rector: Operations, Pura Mgolombane, Dean of Student Affairs, and their Kovsie peers. Prof Morgan encouraged the team to have a wonderful and enjoyable journey, acknowledging that the journey will not be an easy one. “I want you to know that you have the support of everyone here at the UFS,” he said.

Messages of support continue to pour in for the team on the UFS social media platforms. The Qwaqwa Campus SRC President, Hlalele Masopha, also sent his best wishes to his mate, saying, “I wish the President with his crew a quantity of good fortune and extremely good success.” He says, “This is for the betterment of the students and the institution.”

There have been no reports of any injuries or medical defects incurred by the cyclists nor the supporting team who are travelling with them. The team is expected to arrive in Cape Town on 4 December 2017.
