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.”

Two in millions: 2015 Color Runners doused and dressed in colours of the rainbow.

Unleash your inner sparkle at The Color Run’s Varsity Tour. The University of the Free State is a proud host of the 2016 Bloemfontein edition. Be counted among the 5 million Color Runners worldwide who walk, skip, shimmy, or hop for five kilometres in the name of fun and charity.

The Color Run is the largest series of events in the world promoting healthiness and happiness. Arina Engelbrecht, Chief Officer at the Health and Wellness Centre, believes that “active people are happy people.” Consequently, she encourages students, staff members, and the community to join in the festivities.

Run to make a difference

Wearing white and being doused from head to toe in the colours of the rainbow while exercising is a very different way of extending a helping hand to those in need. For every ticket sold, R10 will be donated to the No Student Hungry campaign by The Color Run and Capitec Bank.

After running through four colour stations, a spectacular show awaits you at the finish line. The Finish Festival is a combination of colour throws, rainbows, glitter, music, and dancing.

The Color Run takes place on:

Date: 27 February 2016
Time: 16:00
Place: Cricket Grounds, Bloemfontein Campus.

Tickets are available online: www.thecolorrun.co.za at R250 for the public, R190 for students, including a goodie bag, or R90 without a goodie bag. Children under 10 years of age enter free. You will receive a R200 coupon to spend on The Color Run goodies or any product of your choice. Goodie bags may be collected at the Cricket Grounds from 25 February 2016.
