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.”

Top ‘political analyst’ for Spring graduation

2013-09-15

Live streaming of ceremonies: www.ufs.ac.za/ufslivestreaming/

Graduands and parents can prepare themselves for an exciting Spring graduation, with a top ‘political analyst’ and a young woman who sees and sings with her soul, as guest speakers.

Chester Missing, South Africa’s top puppet political commentator, and Shenley Pretorius, a blind singer, will address the more or less 650 graduands on Thursday 19 September 2013.

A total of 544 bachelors and honours degrees, as well as 106 diplomas and certificates, will be awarded during the graduation ceremony in the Callie Human Centre at the Bloemfontein Campus. The qualifications will be awarded at two ceremonies.

Chester Missing, a presenter on the television programme, Late Nite News with Loyiso Gola, will be 'accompanied' by Conrad Koch, one of South Africa’s most in demand comedy talents.

The 15-year-old Shenley touched people’s hearts nationwide when she appeared on Noot vir Noot, the SABC2 music programme, earlier this year. The teenager is a Grade 9 learner at Prinshof School for the Visually Impaired in Pretoria.

The programme for the different ceremonies is as follows:

09:30 The Faculty of the Humanities awards 160 qualifications, The Faculty of Education 71 qualifications, the Faculty of Law 27 qualifications and the Faculty of Theology 2 qualifications.
14:30 The Faculty of Economic and Management Sciences awards 137 qualifications, the Faculty of Health Sciences 98 qualifications and the Faculty of Natural and Agricultural Sciences 155 qualifications.
