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.”

Mandela Day celebrated with R5 coin laying

2012-07-09

On 18 July 2012, the University of the Free State (UFS), in partnership with Pick n Pay Hyper in Bloemfontein, will celebrate Nelson Mandela Day with a special R5 coin laying ceremony.

The festivities kick off at 12:00 on the Red Square at the Bloemfontein Campus.

Emeritus Archbishop Desmond Tutu will make a special appearance at this event and also deliver a short message.

Schools in the vicinity, UFS staff and students and the public are invited to take part in the coin laying ceremony.

Ms Marissa van Jaarsveld, the coordinator of the Nelson Mandela Day celebrations at the UFS, says the money collected at the event will be used to benefit the No Student Hungry (NSH) campaign, as well as Bloemfontein Child Welfare. NSH is an organisation on the Bloemfontein Campus that provides food bursaries to hungry students with good academic records.

Requests have been sent to schools to collect R5 coins for the event and representatives from the schools will attend the coin-laying.

These schools will be acknowledged for their contributions and there are prizes up for grabs for the primary and high schools that collect the most money.

Learners will deposit their coin contributions during the 67 Minute programme of giving back to the community and they will take part in fun activities. Participating schools are encouraged to be as creative as possible when handing over their R5 contributions.

On the day, there will also will be people with tins at the main entrances to the university for those who want to make a contribution.

The NSH-campaign will also show its support for eradicating world hunger on this day by helping Pick n Pay Hyper in Bloemfontein to package food parcels for the Stop Hunger Now campaign. The packaging of the food parcels will also take place at the UFS.

Members of the public and the media are invited to attend the festivities.
