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.”

“You cannot let your legacy stop here. Use your qualifications to change the life of others.”

This was the call from Dr Muavia Gallie, a guest speaker at one of the Autumn Graduations on the Bloemfontein Campus of the University of the Free State (UFS). He is a School-Turnaround strategist and educational activist.

He was the speaker on 12 April 2016 at the Faculty of Education graduation ceremony in the Callie Human Centre. According to Dr Gallie and other speakers at the graduations, graduates need to use their qualifications for the good of South Africa.

A diverse group of graduates

A total of 3681 qualifications were conferred in seven faculties between 12 and 15 April 2016, the week of ceremonies comprising eight sessions. It was four days of festivities with friends and families gathering to celebrate with graduates.

The large number of graduates consisted of a diverse group. According to Dr Khotso Mokhele, Chancellor of the UFS, the group passing with distinctions was also much more diverse than in past years, especially in the number of female students.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said graduation ceremonies remain the most special days on the UFS calendar.

A total of 22 students from the Center for Universal Access and Disability Support also graduated during the week.

Work for next generation

Sello Hatang, the speaker on 12 April 2016 at the Faculties of Health Sciences, Law, and Theology ceremony, echoed Dr Gallie’s sentiments; “As you leave this university, your work begins for the next generation; to serve the people you care about in any way possible,” said Hatang, the Chief Executive of the Nelson Mandela Foundation.

Other speakers included Dawie Roodt, the most referenced economist in the media in 2015, at the ceremony of the Faculty of Economic and Management Sciences on 14 April 2016. The speaker on 15 April 2016 at the ceremony of the Faculty of Humanities was Nikiwe Bikitsha, one of South Africa’s leading journalists and broadcasters.

Achievers

In the Faculty of Natural and Agricultural Sciences, Madri Brink (Baccalaureus Scientiae Agriculture) received a Senate Medal for the best four-year Baccalaureus degree, while Kyla Hayter (Baccalaureus Scientiae Honores) won the Senate Medal for the best Honours student at the UFS. Willem Carel Brink from the Faculty of Humanities received a Senate Medal for the best three-year Baccalaureus Degree.
