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.”

What if we put it to you that Barry Roux is to visit Kovsies?

The SRC Legal and Constitutional Affairs office, in conjunction with the Law Faculty, are launching the Student Court this week.

Barry Roux, the renowned South African legal representative who served as the defence advocate in the trial of Oscar Pistorius, will be the keynote speaker.

Guest speakers include Judge Lebotsang Bosieloof the South African Supreme Court of Appeal. Prof Caroline Nicholson and Prof Teuns Verschoor are to represent our Law Faculty as Dean and Lecturer, respectively.

In 2014, when Lindokuhle Ntuli occupied the Legal and Constitutional Affairs office within the Student Representative Council (SRC), the concept of this Judicial Branch of Student Governance was conceived.

“I established the Student Court because I strongly believed that we needed a student forum, beyond the University’s Disciplinary Committee,” said Lindokuhle. He added that such a forum allows for dealing with disputes between students and testing the validity of the Student Court’s constitution and the regulations of the university.

The Student Court’s aim is to administer justice according to these documents. It intervenes in decision-making matters between students, associations, or any part of the student body, at a student level. Other functions of this legal body involve regulating irresponsibly behaviour among students in order to uphold the integrity of the University of the Free State.

You are invited to the launch event:

Friday 21 August 2015

17:00

Economic and Management Sciences Auditorium (EBW), Bloemfontein Campus
