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.”

UFS hones focus to nurture world-class research - Business Day
2006-02-10

THE University of the Free State plans to concentrate academic study in five areas to strengthen its status as a research institution, the university said yesterday.

The Bloemfontein-based university will focus on areas it classes as development (economics, health, literacy and other human activities) and social transformation — an analysis of how South African society is changing from a philosophical and political viewpoint.

The other three research areas are new technologies, water resources and security, and food production and security.

“It makes sense to concentrate the university’s human resources, infrastructure, financial resources and intellectual expertise,” said university rector and vice-chancellor Prof Frederick Fourie.

The move introduces a style of research that matches international trends.

Universities in Canada, Britain and Australia are setting up their research departments in this way.

In SA, the universities of Stellenbosch, the Witwatersrand, Cape Town and KwaZulu-Natal have embarked on similar strategies.

Fourie gave the example of his alma mater, the US’s Harvard University, whose Nanoscale Science and Engineering Centre is an example of “clustering” on a larger scale.

The centre is a collaboration with Harvard, the Massachusetts Institute of Technology, the University of California, Santa Barbara, the Museum of Science, Boston, and universities in the Netherlands, Switzerland and Japan.

Fourie said the modern research world was so diverse and complex that no university could cover all bases so it was better to establish areas of expertise that made it different from its peer institutions.

Having scientists and researchers work in teams meant certain issues could be researched and developed in a multidisciplinary manner. “I think it’s the only way in which any university can excel. This will help SA become world class in selected areas,” Fourie said.

It is in chemistry that the cluster model has already had its most visible results, with a slice of the university’s on-campus pharmacological testing company Farmovs, established in the 1980s, sold to the US’s Parexel International.

The company is one of the largest biopharmaceutical outsourcing organisations in the world, providing knowledge-based contract research, medical marketing and consulting services to the global pharmaceutical, biotechnology and medical device industries, according to Biospace, an internet-based company providing resources and information to the life science industry.

President Thabo Mbeki, in his state of the nation address last Friday, committed government to allocating more resources to research, development and innovation, and increasing the pool of young researchers in SA.

He said government would “continue to engage the leadership of our tertiary institutions focused on working with them to meet the nation’s expectations with regard to teaching and research”.

The university used to be home to several A-rated scientists, who are considered by a peer review, conducted by the National Research Foundation, to be world leaders in their fields, but had lost them to other institutions. Fourie hopes to lure them back, and with them postgraduate students and funding for their work.

“At universities where you get a star researcher they tend to attract people and funding; if they leave they take that with them,” he said.

Fourie said R50m would be spent on the project, with some already spent last year and the last disbursements to be made next year.

There is R10m in seed money to gather experts and improve equipment and infrastructure, and R17m has been invested in chemistry equipment and staff.
