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.”

UFS Rose Ball promises to be an unforgettable experience

2005-09-08

On Saturday 15 of October 2005, the Department of Paediatrics and Child Health at the University of the Free State (UFS) in collaboration with Medi-Clinic, are hosting a Rose Ball in aid of children and babies with serious diseases and special needs.

The Bloemfontein public should get ready for one of the most magnificent events ever held in the city.

The Rose Ball promises to offer an evening of glamour, elegance and beauty which will make it an unforgettable and unique event. The Department aims to make the Rose Ball an annual event to which the Bloemfontein public can look forward to with expectation.

“Excellent food and wine, a 35 man symphony orchestra and of course a magical setting awaits those who attend the Rose Ball. We will do everything possible to make guests feel special, so that they return to the Rose Ball year after year. In this way, we can ensure an annual income from this event for children and babies who are very ill and need specialised care,” said Prof. André Venter, Head of the Department of Paediatrics and Child Health.

The Department of Paediatrics and Child Health at the UFS is responsible for the tertiary care, that is highly specialised care, of around 1 000 000 children in the Free State, Northern Cape, North-West, Eastern Cape and Lesotho. Approximately 13 000 out-patients are treated at the Universitas and Pelonomi Hospitals annually. Children who suffer from cancer, heart disease, neurological disease and endocrinological and gastro-enterological conditions are treated. The Department is also responsible for children who need intensive care and children with contagious diseases. In addition, there is a large neonatal unit where prematurely born babies are treated.

The level of health care needed to treat these children and babies, necessitate highly specialised equipment and knowledge. However, it is not always possible to replace or upgrade equipment, due to the lack of much-needed funds. That is why a fund was created within the Department to satisfy the need for funds. The Rose Ball promises to eventually give a vital boost to the fund that will go a long way toward providing in the special healthcare needs of these patients.

The Rose Ball is made possible thanks to the support of Medi-Clinic.

“Medi-Clinic is honoured to be involved in this great effort and in this way take hands with the Department of Paediatrics and Child Health at the UFS. There are so many children with life-threatening diseases today and we cannot afford to be uninvolved in any effort to make life better and easier for these children. We at Medi-Clinic, as a private sector company, look forward to establishing a long-term commitment with the Department of Paediatrics and Child Health,” said Mr Sakkie van der Merwe, Hospital Manager of Bloemfontein Medi-Clinic.

Only a limited number of tables are still available for the Rose Ball. Tickets cost R500 per person or R5 000 per table of 10 people.
