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.”

Council votes on appointment of senior staff

2004-11-18

The Council of the University of the Free State (UFS) today voted on the filling of three senior vacancies, including one post at Dean level and two at the level of Vice-Dean.

The Council voted as follows:


Dr Natie Luyt will be offered the post of Dean: Student Affairs	Prof Engela Pretorius will be offered the post of Vice-Dean: Faculty of Humanities	Dr Choice Makhetha will be offered the post of Vice-Dean: Student Affairs

“There are special challenges for the UFS in the short and medium term regarding transformation of our residences, and a certain combination of management qualities and skills is desirable. As a result of the diversity of the UFS’s student community it is therefore important to us to follow a team approach to deal with the challenges. With the combination of Drs Luyt and Makhetha, I believe we will be able to manage student affairs effectively and skillfully,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“It is wonderful that we are able to celebrate the outcome of this process that has brought forward such excellent candidates who reflect our country’s diversity. It shows that we can achieve the goals of quality and diversity at the same time,” says Prof Fourie.

Prof Pretorius obtained all her qualifications (BA, BA (Hons) (cum laude), MA (cum laude) and D Phil) from the UFS, except for the Certificate in Gender Policy Management (cum laude) which she obtained in 2000 from WITS. She joined the Department of Sociology at UFS in 1980 and has headed the Department since 2001. She acted as Vice-Dean: Faculty of Humanities since July 2004. She has some thirty publications to her credit, published both nationally and internationally and has delivered 20 national and international papers. She is a member of the South African Sociological Association and is a member of the Council of the association and of the Editorial Board of Society in Transition, the society’s journal. She is also a member of the South African Academy for Science and Art and the Federation of African Women Educationalists in South Africa (FAWESA). Project involvement includes the Australian Women’s Executive Development Programme and the project Executive Development of Senior Women in South African Higher Education Institutions. She is also an NRF panelist.

Dr Luyt obtained his qualifications (BA, BA (Hons) (cum laude), MA (cum laude) and D Phil) at the UFS and started his career at the same institution in 1980 as lecturer in Political Science. He was promoted to senior lecturer in 1983 and appointed as Director: Student Affairs in 1997. He has been acting as Dean: Student Affairs since 2003. Dr Luyt completed several work-related training courses, among others a course in ethnic and multiculturality at the Swiss Institute for Federalism and a course in conflict management at the South Tyrolean Economic and Social Institute.

Dr Makheta also obtained all her qualifications (BA, BA (Hons), MA in Political Science and Ph D in Political Science) at the UFS and started working as a student assistant in Political Science at the same institution in 1999. She was promoted to junior assistant in 2000, coordinator and facilitator of Political Science in 2001, assistant/acting Director: Student Affairs in 2001 and acting Director: Student Affairs in 2003. Dr Makhetha is currently a Senior Political Analyst at the Department of Foreign Affairs.

The UFS Council also approved the promotion of nine professors to the rank of senior professor. They are Proff Louise Cilliers (Department English and Classical Languages), Dap Louw (Department of Psychology), Philip Nel (Department Afro-Asiatic Studies, Sign Language and Language Practice), Dirk van den Berg (Department of History of Art and Visual Culture Studies) Dingie van Rensburg (Director: Centre for Health Systems Research and Develoment), Andries Raath (Department of Constitutional Law and Philosophy of Law), James du Preez (Department of Microbial, Biochemical and Food Biotechnology), Johan Grobbelaar (Department of Plant Sciences) and Louis Scott (Department of Plant Sciences).

This is the first group ever of senior professors at the UFS. The post level was created to provide better career and earnings opportunities for high quality academics and to increase the attractiveness of an academic career to young people.
