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.”

Communication from within and below: Social Transformation and Inclusiveness. That was the theme of the 2016 South African Communication Association (SACOMM) conference, hosted at the Bloemfontein Campus of the University of the Free State (UFS) from 3 to 5 October 2016.

“Through this theme, participants were invited to submit papers that examined the role of communication in today’s tumultuous climate,” said Prof Mili Rivera, Head of the Department of Communication Science at the UFS.

A total of 140 delegates from other South African universities, as well as international delegates from Zimbabwe, Nigeria, the United Kingdom, United States, and Australia attended the conference. It was the second time in ten years that the UFS hosted the conference.

Organisation to mentor and support emerging scholars
Various staff members and students from the UFS Department of Communication Science presented papers during the three days.

Annette van Baalen and Dr Dalme Mulder, both lecturers in the department, won the best paper award in the Corporate Communication division. A number of emerging scholars also presented papers. “The organisation is committed to mentoring and supporting emerging scholars in the field of Communication Science,” said Prof Rivera.

Association must be agent of change in curriculum
Delegates discussed the role of the organisation (SACOMM) as an agent of change in terms of decolonising the curriculum. The focus was on training journalists to cover crises in a fair and balanced manner. The book The Art of Persuasive Communication - A Process (4th Edition) by Prof Johann de Wet, former head of the UFS Department of Communication Science, was also launched during the conference.

The next SACOMM conference will take place at Rhodes University in 2017.
