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.”

International delegates rethink justice and righteousness at Theology conference

2015-09-07

Participants in the multidisciplinary conference hosted by the UFS Faculty of Theology, celebrated the 35^th anniversary of the faculty with a festive dinner.

The Faculty of Theology at the University of the Free State (UFS) held a multidisciplinary conference from 24 to 26 August 2015, with the theme of ‘Re-thinking justice and righteousness in society’. A total of 26 papers were presented at the congress, with contributions from Theology, Economic and Management Sciences, the Humanities, and Law. Delegates from Nigeria, Zimbabwe, Zambia, and Belgium attended the conference, in addition to academics from the UFS.

Some of the keynote speakers at the international conference hosted by the UFS Faculty of Theology, ‘Re-thinking justice and righteousness in society’: Prof Fanie Snyman, Dean of the UFS Faculty of Theology, Rev Peter Awojobi, Rev Menard Musendekwa and Prof Ango Samuel.

“With this conference,” said Prof Fanie Snyman, Dean of the UFS Faculty of Theology, “we are positioning the faculty alongside other faculties whose insights and disciplines are important to Theology. A multidisciplinary forum also provides great possibilities for

cooperation across disciplines.”

The conference coincided with a visit to the UFS by students in the theological faculties at the Universities of Stellenbosch and Pretoria. These students attended some of the presentations, in addition to the other activities they were involved in.

The Faculty of Theology is celebrating its 35th anniversary this year, making it not only the youngest faculty at the UFS, but also the youngest theology faculty in South Africa. In this time, the faculty has established itself as a significant role player within the theological landscape, with important agreements having been reached with theological institutions in Europe, the USA, and Africa.
