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.”

Diligence to be rewarded at the 2015 Spring Graduation

2015-09-15

The hard work of many students finally comes to fruition with this year’s spring graduation ceremonies taking place on Thursday 17 September 2015 on the Bloemfontein Campus.

A total of 124 diplomas, 419 bachelors and 56 honours degrees will be conferred on graduates from all seven faculties of the University of the Free State (UFS). In addition to the 599 conferrals, Professor Jeffrey Sachs, the world-renown American economist, will round out the number to 600 as the recipient of an honorary doctorate.

The Faculty of Economic and Management Sciences wishes to express appreciation for his extensive contribution towards economic, social, and political development across borders with an honorary doctorate in Economics.

Prof Sachs has had a positive impact on global peace and security, climate change, sustainable development, human rights promotion, and governance through various platforms, including being a Special Advisor to United Nations (UN) Secretary-General, Ban Ki-moon, on the Millennium Development Goals (MDG). He also served as the Secretary-General’s MDG Advocate and Commissioner of the International Telecommunication Union (ITU)/United Nations Educational, Scientific and Cultural Organization (UNESCO) Broadband Commission for Development.

In addition, Prof Sachs serves as the Director of the Earth Institute at Columbia University and Director of the UN Sustainable Development Solutions Network. As an author, he has featured three times on the New York Times bestsellers list, and is the co-founder of the Millennium Promise Alliance, and drives the Millennium Villages Project as its Director.

Graduates should expect words of salutation and encouragement from our main speaker, the Vice-Chancellor and Rector of the university, Prof Jonathan Jansen.

Two ceremonies will take place in the Callie Human Centre at 09:00 and 14:00 respectively. Attendees of the afternoon ceremony will witness the conferment of Prof Sach’s degree. There is a live stream option available on the university’s website to individuals who are unable to attend the ceremonies.
