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 professor receives international recognition for exceptional ethical values
2015-10-02

“You grow so fond of them,” Prof André Venter,
Head: Department of Paediatrics and Child Health,
says while doing his rounds with patients.
Prof Venter recently received the award for health professions
from the international organisation, Unashamedly Ethical.

“You are such a pretty baby,” Prof André Venter, Head: Department of Paediatrics and Child Health at the University of the Free State, whispers to a baby lying stretched out in her neonatal cradle.

He uses his fingertips to free her legs and arms carefully from the monitors and wires attached to her.

“See how much you have grown,” he says, tapping with his finger on her file. 1.2 kg - her weight indicates. 

In one of the other children’s wards, he joins a mother sitting with her sick baby. Speaking about the baby’s operation coming up within the next few months, he gives her an encouraging pat on the shoulder.

He visits yet another mother who is practising kangaroo care on her baby, and asks to hold the baby for a while.

“Gosh, you’re so nice and warm, let doctor hold you for a while,” he says, hugging the premature baby to his chest.

Prof Venter greets and thanks the nursing staff at the end of his ward rounds.

“Everything is not always good, but one can try to plan for the future from the challenges,” he says. “One should never concentrate on the immediate problem too much, but lift the morale of those using our services, those providing the services, and those who come here for training.”

It is this kind of passion and outlook that earned Prof Venter an ethical award from the international organisation, Unashamedly Ethical. The award, which was made in the health professions category, recognises doctors for exceptional ethical values and for going the extra mile in alleviating the suffering of humanity.

“I am humbled at being honoured for something I see as my passion and actually take for granted. I am also touched that people from outside noticed and nominated me for this,” he says.

He talks about his young patients again: “I learn so much from them each day. Children are so resistant to negative things. I grow so fond of them that I forget they have to go home some time.”
