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.”

More than 200 people, amongst them the Deputy Minister of Higher Education and Training, Prof. Hlengiwe Mkhize, came together at our university to reflect on the life of ANC Women’s League stalwart Charlotte Maxeke, during the Charlotte Maxeke Memorial Lecture organised annually by the Free State Provincial Government and our university as a lead-up to National Women’s Day on Tuesday, 9 August 2011.

This year was the fourth memorial lecture and Prof. Mkhize delivered the main address under the theme “Women’s access to education, science and technology for economic growth and development in bringing about positive change, living in extraordinary times”

Prof. Mkhize told guests Charlotte Maxeke’s life was too rich and complex to capture during the night and listed many of Maxeke’s achievements during her life and times. These included Maxeke being the first woman to graduate with a science degree from the University of Wilberforce, Ohio. Prof. Mkhize said Charlotte Maxeke’s science degree was not a personal achievement, because she went back to the people and served by opening the Wilberforce Institute in Evaton, Vereeniging, after her return from the United States.

Prof. Mkhize applauded our university for organising the lecture, saying the university’s commitment was appropriate for the contribution Charlotte Maxeke made to women’s empowerment. She said government have a huge interest in our university and said the lecture provided an opportunity to dialogue and to use the experience to improve the country’s institutions. Delivering the last part of her address, Prof. Mkhize said she hopes the lecture will lead to great things, with the local community also becoming involved in organising the event.

Dr. Choice Makhetha, Acting Vice-Rector: External Relations, announced at the event that the university will open a women’s memorial garden on Tuesday, 9 August 2011 to honour women who made a contribution in society.
