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.”

Champion of human rights – Prof Martha Minow – to present the Third Annual Reconciliation Lecture

Prof Martha Minow, Dean of Harvard University’s Law School, will be delivering the highly-anticipated Third Annual Reconciliation Lecture on Monday 24 February 2014. Her lecture entitled “Forgiveness, Law and Justice” promises to evoke healthy debate and honest introspection.

In an interview, Pres Barack Obama has been quoted to say that, as a teacher at Harvard Law School, Martha Minow changed his life. He cited her as being instrumental in his decision to pursue community service instead of commercial law.

Prof Minow – a sheer force of nature – has established herself globally as an advocate of human rights and protector of minorities. The effects of her work are rippling across continents. Her passion for the law has resulted in legislative initiatives that opened access to curricular materials for individuals with disabilities in the United States. She serves as Vice-Chair for an organisation providing assistance to low-income Americans. In addition, Prof Minow has also helped launch a programme called Imagine Co-existence for the UNHigh Commissioner for Refugees. The aim of the programme is to promote peaceful development in post-conflict societies.

The Annual Reconciliation Lecture is organised from the office of Prof Pumla Gobodo-Madikizela. This yearly event was established by Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS. The main objective is to bring scholars to our university whose leadership and vision for social change and conflict transformation is reflected in their interaction within the academe and their teaching. This initiative supports the university’s drive to achieving excellence not only in the field of academics, but in human reconciliation as well.

The details of the event:
Date: Monday 24 February 2014
Time: 17:30 (please be seated by 17:15)
Venue: Centenary Complex, Reitz Hall, BloemfonteinCampus

The public is welcome to attend.
If you would like to attend the lecture, please confirm with Jo-Anne Naidoo at NaidooJA@ufs.ac.za

The lecture will be streamed live on:http://www.ufs.ac.za/ufslivestreaming/
