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.”

Kovsies to celebrate excellence at 2014 December Graduation Ceremony

2014-12-02

Live streaming: http://apps.ufs.ac.za/ufslivestreaming/

On Thursday 11 December 2014, the University of the Free State (UFS) will award degrees and qualifications during our Summer Graduation Ceremony at the Bloemfontein Campus.

The graduation will take place during two ceremonies in the Callie Human Centre, where master’s and PhD degrees will be awarded during the first ceremony at 09:30. Diplomas, certificates and undergraduate qualifications will be awarded to students from the School of Open Learning and the Faculty of Health Sciences at 14:30.

Radio personality, Redi Thlabi, and cardiothoracic surgeon, Dr Susan Vosloo, will address the graduates.

Apart from her radio show on 702 and CapeTalk, Thlabi has also hosted local television news shows and anchored for international broadcasters like SKY and the BBC. In addition, she has presented two of her own TV shows: ‘Redi’ on Mzansi Magic and ‘South to North’ on Al-Jazeera.

Her first book, Endings and Beginnings (Jacana) received popular acclaim and is currently being turned into a screenplay for a movie.

Dr Susan Vosloo, a Kovsie alumnus, graduated in 1980. She completed her internship in Pretoria and spent the following year in Critical Care Medicine at Universitas Hospital, Bloemfontein, before starting her surgical training in Johannesburg.

She is currently in independent private practice at the Netcare Christiaan Barnard Memorial Hospital in Cape Town, having also worked from 1998 – 2012 at the Vincent Pallotti Hospital in the same city.

Dr Vosloo maintains close ties with our university and has quite a number of addition roles to that of surgeon:

• member of the Council of the UFS;
• UFS Council Representative in the Senate;
• member of the Standing Advisory Committee of the School of Medicine, UFS;
• member of the Provincial Department of Health;
• Africa representative for the Pediatric Cardiac Intensive Care Society; and
• founding member of the World Society for Pediatric and Congenital Heart Surgery.

Prof Boelie Wessels will also be awarded his 10th academic degree from the UFS since 1974. Adding his Honorary Doctorate degree to the list, it will make this his 11th degree. Prof Wessels is 84 years old and has 18-plus academic qualifications from various institutions – a phenomenal achievement.

Furthermore, Moses Lubinga and his wife, Stellah, will be the first married couple to be awarded their PhDs at the same graduation ceremony at the UFS. Mr Lubinga will receive his Doctorate in Agricultural Economics, while Mrs Lubinga’s PhD is in the field of Economic and Management Sciences.
