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.”

"Studies indicate disability, poverty and inaccessibility to healthcare are intricately linked " - expert opinion by Dr Magteld Smith
2014-12-03

Dr Magteld Smith

Programmes worldwide attempt to improve the lives of people with disabilities, but recent studies indicated that disability and poverty, as well as disability and the inaccessibility of health care, continues to go hand in hand.

In South Africa, and even in developed countries, research shows that people with disabilities achieve lower levels of education with higher unemployment rates, live in extreme poverty and have low living standards.

“To have a disability can therefore become a huge financial burden on either the disabled person, the family or caregivers,” says Dr Magteld Smith from the Department of Otorhinolaryngology.

She devotes her research to the medical-social model of the global organisation, the International Classification of Functioning, Disabilities and Health, focusing on all areas of deafness.

Furthermore, Dr Smith says it is more difficult or more expensive for people with disabilities to obtain insurance, because of the risks associated with disability.

Dr Smith also emphasises the inaccessibility and even unavailability of medical services or health care for people with disabilities.

“Services such as psychiatry or social services are often not accessible. When such services are available, it is not affordable for most people with disabilities.”

Dr Smith uses the example of a person who was born deaf:

“Doctors have limited knowledge of the different types of hearing impairments or how to read and interpret an audiogram. Very little understanding also exists for the impact of deafness on the person’s daily life.”

Dr Smith, who is deaf herself, describes the emotional state of mind of people with disabilities as a daily process of adjustment and self-evaluation.
