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.”

Tswelopele hosts first LGBTQI panel discussion

Ignorance about issues relating to the Lesbian, Gay, Bisexual, Transgender, Queer and Intersex (LGBTQI) community is a threat to mankind. This is according to Tshepang Mahlatsi, former Prime of Tswelopele residence, regarding LGBTQI concerns at University of the Free State (UFS).

House Tswelopele on the Bloemfontein Campus hosted a panel discussion, Brotherhood with no Limit, on 19 September 2016 to discuss issues affecting the LGBTQI community, which has often been on the receiving end of criticism, hate speech and bigotry.

Academics take stance at LGBTQI discussion

The panel, which consisted of staff members and students, opened the discussion to everyone on campus. The panel comprised Zane Thela, Programme Coordinator: Gender and Sexual Equity Office: Student Affairs; Dionne van Reenen, Assistant Researcher; Dr Thierry Luescher, Assistant Director, Directorate for Institutional Research and Academic Planning, and Mahlatsi.

Creating a safer environment for LQBTQI dialogue

“The message that we were putting across was simple. We as a house cannot allow society to define our own brothers for us,” Mahlatsi said. The responsibility of students and student leaders was to stand in solidarity. He said it was not fair that in the 21st century people were still fighting to be recognised for who they were and what they identified themselves as. This issue had been discussed at Tswelopele before and it was not that much of an issue, Mahlatsi said. “However, this was the first formal one [discussion] where we had speakers who are more informed on the topic.”

The panel discussion also aimed to challenge other residences that still do not allow such talks to take place in a safe environment.
