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.”

‘Africa’s Many Liberations’ seminar series launched
2016-05-11

Description: Seminar Series Tags: Seminar Series

The Africa’s Many Liberations seminar series, presented on the Bloemfontein Campus of the University of the Free State (UFS), is a direct response to some of the demands made by the #MustFall campaigns during the past year. A constant refrain among activists has been that the curriculum must be ‘decolonised’, and that it should have stronger foundations in African experiences. This seminar series aims to deepen understanding of histories and anti-colonial struggles, including those waged worldwide today.

It was conceived to deepen students’ knowledge of African and South African history, and to help them to engage with ideas from the diaspora and anti-colonial struggles elsewhere. It was planned as a popular seminar for students across faculties. For this reason, the series strives to avoid language or literature that might exclude students from disciplines outside of historical, sociological, political, and cultural studies.

The series is convened by the International Studies Group (ISG), in association with the Institute for Reconciliation and Social Justice (IRSJ). The coordinator is Prof Neil Roos (associate professor of history in the International Studies Group, and co-director of the Vice-Chancellor’s Prestige Scholars Programme).

Prof Roos presented the first seminar, entitled Du Bois and the ‘Problem of the Colour Line’ on Thursday 28 April 2016. The next theme under discussion will be Fanon and the Relevance of Personal and Collective Decolonisation in Today’s South Africa, which will be presented by Dr Tinashe Nyamunda.

The remainder of the eight-part series will be presented by Dr Rachel Hatcher (postdoc in the IRSJ), Dr Sahar Sattarzadeh (postdoc in the IRSJ ), Dr Ivo Mhike (postdoc in ISG), Busi Ntsele (lecturer in sociology), Leigh-Ann Naidoo (doctoral student and activist, University of the Witwatersrand, South Africa), and Prof Richard Pithouse (associate professor in politics, Rhodes University, South Africa).

Date: Thursday 12 May 2016
Time: 16:30
Venue: Albert Wessels Auditorium, Bloemfontein Campus
Entrance is free
