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 presents unique rally

2006-05-11

On Friday 9 June 2006 the University of the Free State (UFS) will present the second Amazing Race Rally in Bloemfontein.

The rally is presented in aid of children and babies with serious diseases in the Department of Pediatrics and Child Health in the UFS Faculty of Health Sciences. These children are in need of intensive care, and suffer from cancer, heart disease, neurological diseases and conditions, endocrinological diseases or gastro-enterological conditions.

By raising the necessary funds, equipment can be acquired to meet the unique healthcare needs of these children and babies and it will also enable the UFS to maintain the high standards of education, training and research in this field.

Last year about 12 corporate teams from among others Vodacom, Medi-Clinic, Eskom, Mimosa Mall and Nedbank and four teams from the UFS competed in the rally. The Medi-Clinic team was the winner.

This year the teams will again follow a specific route with various check points by car. Here they will have to complete activities or solve clues before receiving their clue to the next checkpoint. The teams will be travelling with cars branded with the logo of the company they represent.

Companies and institutions in Bloemfontein can enter in the rally by means of sponsoring a check point, entering a team of two persons or sponsoring some aspects of the day.

The rally will give participants an opportunity to test their knowledge of the city, as well as their time management skills, communication skills, team work and even their relationships!

The programme will start at 12:00 on the UFS Main Campus and the first team to complete this task is the winner of Bloemfontein’s second Amazing Rainbow Rally.

Extensive publicity of the event on OFM in the weeks running up to the day will ensure that participants are easily recognised and will create a measure of excitement.

Enquiries about the rally can be directed to Ms Adéle van Aswegen at (051) 401-3535 or Ms Ilse Olivier at (051) 401-2415.
