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.”

Caregivers for haemophilia patients, and patients themselves from around the Free State and Northern Cape attended a home infusion workshop held by the Clinical Skills unit in the Faculty of Health Sciences in July 2017. “It felt liberating and I feel confident to give the factor to my son correctly,” said Amanda Chaba-Okeke, the mother of a young patient, at the workshop. Her son, also at the workshop, agreed. “It felt lovely and good to learn how to administer factor VIII.” 

Clinical skills to empower parents and communities

There were two concurrent sessions: one attended by doctors from the Haemophilia Treatment Centre, and the other attended by community members including factor VIII and XI recipients, caregivers and parents. The doctors’ meeting was shown informative videos and demonstrations on how to administer the newly devised factor VII and XI kit, and discussed the pressing need for trained nurses at local clinics. Dr Jaco Joubert, a haematologist, made an educational presentation to the community members.

The South African Haemophilia Foundation was represented by Mahlomola Sewolane, who gave a brief talk about the role of the organisation in relation to the condition. Meanwhile, procedural training in the simulation laboratory involved doctors and nurses helping participants to learn the procedures by using mannequins and even some volunteers from among the patients.

A medical condition causing serious complications
Haemophilia is a medical condition in which the ability of the blood to clot is severely impaired, even from a slight injury. The condition is typically caused by a hereditary lack of a coagulation factor, most often factor VIII. Usually patients must go through replacement therapy in which concentrates of clotting factor VIII (for haemophilia A) or clotting factor IX (for haemophilia B) are slowly dripped or injected into the vein, to help replace the clotting factor that is missing or low. Patients have to receive this treatment in hospital.
