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.”

Dr Khotso Mokhele joined the ranks of distinguished Chancellors of the University of the Free State (UFS) with his inauguration as the new Chancellor of the institution at a ceremony on Friday, 19 November 2010.

The lustrous ceremony took place on the Main Campus in Bloemfontein and was attended by hundreds of guests from all over South Africa.

Dr Mokhele said in his speech: “I am excited to have been invited by the UFS to join its community at the time when it is attempting to reinvent itself into an institution that will be counted amongst those that will shape the local, regional, national will, and by so doing, contribute to the shaping of an African will.”

Dr Mokhele follows in the footsteps of Dr Franklin Sonn, former Ambassador of South Africa in the United States of America and receiver of many awards, acknowledgements, and honorary doctorates, who retired earlier this year. Dr Sonn was preceded by Ms Winkie Direko, former premier of the Free State.

His acceptance of the role of Chancellor is a great honour for the UFS.

According to Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, it is a proud moment to welcome someone from the Province as the Chancellor of this university. With his strong academic values and deep sense of human compassion, Dr Mokhele is one of but a few uncompromising leaders. He is also an inspiring, determined pioneer and a role model to all our students.

Few have done as much to guide the development of science in South Africa since democracy in 1994 as Dr Mokhele. His vision and actions as a senior science manager have been guided by his deep conviction that for a truly democratic society to emerge in South Africa all people must be empowered to be its architects and must have unhindered access to those careers upon which our economy is built.

Dr Khotso Mokhele was born and raised in Bloemfontein. After matriculating from the Moroka High School he went on to study at Fort Hare, where he graduated with a B.Sc. in Agriculture, winning the Massey-Ferguson award for the best student in that field. As a recipient of the prestigious Fulbright-Hays Scholarship, he entered the University of California in Davis where he took a M.Sc. and a Ph.D. degree, both in Microbiology. He was awarded post-doctoral fellowships at the Johns Hopkins University School of Medicine in Baltimore, Maryland, and at the University of Pennsylvania, Philadelphia.

Dr Mokhele returned to South Africa in 1987, set on becoming a top-class academic and researcher. He held lecturing posts at the Universities of Fort Hare (1987-1989) and Cape Town (1990-1992). In 1992 he joined the Foundation for Research Development (FRD) as one of its Vice-Presidents. He succeeded to its presidency in 1996 and then from 1999 to 2006 became the first President of the National Research Foundation (NRF). He successfully merged the FRD and the Centre for Science Development of the Human Sciences Research Council. Under his visionary leadership the NRF has come to play a pivotal role in the development agenda of the country. He was also instrumental in the establishment of the South African Academy of Sciences serving as its founder president (1996-1998).

Dr Khotso Mokhele's contribution to science in South Africa has received wide recognition locally and abroad. He has received nine honorary doctorates. He was made a Chevalier of the Legion of Honour by the President of France in recognition of his personal efforts in strengthening scientific ties between France and South Africa, and was appointed a director of the Salzburg Seminar, an institution focused on global change, and subsequently a member of its Council of Senior Fellows.

He also serves on the boards of major companies such as Implats, Adcock Ingram and Afrox.
