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.”

Leadership and responsible citizenship: key themes at the Global Leadership Summit

Leadership and responsible citizenship have been the main topics of discussion at the Global Leadership Summit which started on 5 July at the UFS Campus in Bloemfontein, and will continue until 17 July. More than 103 international delegates from various universities in Asia, the United States, and Europe, as well as 40 student delegates from the University of the Free State, are attending.

Kick-starting the summit talks was Prof Joel Samoff (Stanford University) who led discussions on transformation in institutions around the world. “Transformation is a constantly-changing interaction. It is not a single objective, but a process, “ he said. This was followed by a robust panel discussion with student leaders of the UFS and those from James Madison University, Mount Holyoke College, and Rutgers University, who described the journey of transformation at their various universities. “Young people are leading themselves in a different way, the context of the society we live in has changed,” said a UFS Student.

Keynote speaker, Zelda la Grange, gave an account of her experiences and the colourful journey of discovery of a “different” South Africa, working with President Nelson Mandela for 19 years, a journey that is the subject of her book, “Good Morning Mr Mandela “. Under the theme “Breathing the same air: A metaphor for human solidarity, Prof Pumla Gobodo-Madikizela, Senior Research Professor in Trauma, Forgiveness, and Reconciliation Studies led a talk with Candice Mama, the daughter of slain anti-apartheid activist, Gelnack Masilo Mama, one of the victims of the former hit squad commander, Eugene de Kok. Candice inspired the audience with her philosophy on life and letting go of trauma: “Forgiveness is a process, and one needs to forgive to be able to be liberated from anger and bitterness,” she said.

Dr Lis Lange, Vice Rector: Academic, UFS spoke of citizenship and freedom, focusing on the responsibility that humans have to create ethical, positive, and meaningful interaction in their daily lives and in their societies across the globe.

As part of the programme, delegates will visit the Qwaqwa Campus on 10 July 2015, where they will interact with the leadership of the campus, its staff, and students, and enjoy an arts and cultural experience of the Eastern Free State. The summit will end with a visit to various sites in Bloemfontein, where delegates will engage in community-based outreach activities in disadvantaged communities around the city.
