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.”

Historic Global exchange summit for first-year students in 2012
2011-10-21

 
More than one hundred Kovsie first-year students travelled to universities in the USA and Europe in September 2011 to learn about issues such as diversity, leadership and citizenship. More students will travel to Asia in January 2012. Daniel King, Melissa Lucas, Jomari de Beer and Rito Madingana visited Ghent University in Belgium.

Our University will present a global exchange partner summit next year with the 16 partner universities who took part in this year’s Leadership for Change Programme. This will be the first summit of its kind presented in South Africa bringing together first-year students from four continents and 17 countries. The summit will take place from 8 - 22 July 2012 on the Bloemfontein Campus.

The aim of the summit is for first-year students from all partner universities in the USA, Europe and Asia to visit our university and experience student life at a South African university. The students will be staying on campus and an intensive programme covering issues such as social justice, diversity, leadership and citizenship will be presented.

Mr Rudi Buys, Dean of Student Affairs at our university, says the summit will serve as an opportunity to detail further partnership agreements with a number of universities such as Binghamton State University, amongst others.
