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.”

University hosts International Feminist Journal of Politics first annual conference

2012-07-31

The university will host the first annual international conference organised by the prestigious international journal International Feminist Journal of Politics.

The conference will take place from 2 to 4 August 2012 on the Bloemfontein Campus and will coincide with national women’s month celebrations. The theme of the conference is “Leaving the Camp – Gender Analysis across Real and Perceived Divides”. Several leading scholars will participate in the proceedings.

Inderpal Grewal, Professor of Women’s, Gender and Sexuality Studies at Yale University in the United States and author of Transnational America: Feminisms, Diasporas, Neoliberalisms will deliver the keynote lecture entitled “Outsourcing Patriarchy: Media, Violence and Transnational Feminisms”.

Prof. André Keet, Director of the International Institute for Studies in Race, Reconciliation and Social Justice will deliver a keynote address at the Women’s Day Dinner on 2 August 2012. The topic will be "Clean shaven Marx [s]? Rights, Necromancy and Conceptions of Feminist Justice".

In addition, Prof. Amanda Gouws, Professor in the Department of Political Science at Stellenbosch University and also newly appointed Commissioner in the Commission for Gender Equality, will facilitate a feminist methodology workshop on “Working across Disciplinary and Professional Borders”.

The International Feminist journal of Politics offers a unique cross-cultural and international forum to foster debate and dialogue at the intersection of international relations, politics and women’s studies. Developed by a team of leading feminist scholars, this journal brings together some of the most influential figures in the field to build a global critical community of writers and readers.

The lecture by Inderpal Grewal takes place in the Business School Auditorium from 10:45-12:00 on 3 August. The lecture is open to the public, but please take note that space is limited.

For further information, please contact Prof. Heidi Hudson at hudsonh@ufs.ac.za or visit http://ifjp.z2a.co.za.
