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.”

Summer programme a first outside Austria

People often fight about their differences, like skin colour, religion and more. “These differences are minute. We must celebrate our common ancestry and commit ourselves to a common destiny. Your work can make a difference.” This is according to Mr Derek Hanekom, Minister of Science and Technology.

He opened the Southern African Young Scientists Summer Programme (SA-YSSP) at the Bloemfontein Campus on Sunday 2 December 2012. The UFS is the first institution outside Austria to host the Summer Programme. A total of 19 young researchers from 17 countries will be hosted by the UFS until 28 February 2013. Researchers in the programme are, among others, from South Africa, Egypt, China, Italy, Sweden, Iran, Hungary, India, the USA and Indonesia.

The programme will form part of an annual three-month education, academic training and research capacity-building programme jointly organised by the International Institute for Applied Systems Analysis (IIASA), based in Austria, the National Research Foundation (NRF) and the Department of Science and Technology (DST). IIASA is an international research organisation that conducts policy-oriented scientific research in the three global problem areas of energy and climate change, food and water and poverty and equity. South Africa’s engagements with IIASA, specifically with regard to the SA-YSSP, relate primarily to the DST’s Ten-Year Innovation Plan.

Mr Hanekom spoke about the impact the growing global population, which is expected to grow from 7 billion in 2012 to 9 billion in 2050, has on natural resources. “We use purified water to flush our toilets while other people do not have clean drinking water. We cannot carry on like this. Somewhere it must stop, if we do not want to be responsible for the 6th great extinction. We must know how our systems impact on each other.

“We can do things differently and better and should endeavour that other people enjoy luxuries we take for granted,” he said.

He urged the researchers to believe that they can make a difference, share knowledge and translate the knowledge into plans.

Prof. Dr Pavel Kabat, Director/CEO of IIASA, said the summer programme was presented outside Austria for the first time, with plans to expand to Brazil and China in future. Twenty countries are represented on the IIASA board, with more than 3 000 researchers associated with the organisation.

IIASA was launched in 1972 in the days of the Cold War as a “science bridge” between the West and the Soviet Union. It served as a “think tank” for various issues that needed to be resolved. Its mission was reconfirmed after the fall of the Berlin Wall in 1989.
