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.”

Record amount of degrees and diplomas awarded during Spring graduation ceremony

2005-09-12

The University of the Free State (UFS) will award a record amount of 885 degrees and diplomas on Thursday 15 September 2005 to students from the Vista and Main campuses during this year’s spring graduation ceremony.

Altogether 572 degrees and 313 diplomas will be awarded. This is the most degrees and diplomas that have been awarded during the spring graduation ceremony.

One honorary doctorate and 30 doctorates will also be awarded. The honorary doctorate Doctor Theologiae (honoris causa) will be awarded to Prof Wilhelm Neuser for his contribution to the promotion of international Calvin research and for his insight and personal dedication to involving South Africans in it.

In the Faculty of Health Sciences 74 degrees, 26 diplomas and 2 doctorates will be awarded, in the Faculty of Humanities (excluding the School of Education) 90 degrees, 9 diplomas en 6 doctorates will be awarded. In the Faculty of Law 31 degrees will be awarded, in the Faculty of Natural and Agricultural Sciences 127 degrees, 2 diplomas and 15 doctorates will be awarded, in the Faculty of Economic and Management Sciences 173 degrees, 2 diplomas and 2 doctorates will be awarded and in the Faculty of Theology 13 degrees, 4 diplomas and 1 doctorate will be awarded.

In the School of Education 64 degrees, 273 diplomas and 1 doctorate will be awarded.

The diploma ceremony will start at 08:30 and the graduation ceremony will start at 14:30. Both ceremonies will take place in the Callie Human Centre on the Main Campus.
