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.”

Albert Einstein “visits” Bloemfontein

2005-08-30

Albert Einstein, performed by David Muller, and Dr Matie Hoffman, senior lecturer from the Department of Physics at the UFS and coordinator of educational activities at the UFS Boyden Observatory. They are standing at the 1,5m Boyden telescope.

Visitors to the University of the Free State’s (UFS) Boyden Observatory had a special treat on Saturday 27 August 2005 when they were “Albert Einstein”, alias David Muller (Albert Einstein in Imagining Einstein) paid them a surprise visit.

The Department of Science and Technology is sponsoring a one-man play called Imagining Einstein. The play, written and performed by David Muller, is produced through the MTN Science Centre and forms part of the celebration of the World Year of Physics. The play’s visit to Bloemfontein was kicked off by Saturday evening’s performance at the UFS Boyden Observatory.

It follows the life of Einstein, from his patent office in Switzerland, through his office in Berlin to his position at Princeton where he spent the last 20 years of his life and captures the research, studies and thinking with all its depth and insights of a man who not only changed the thinking about physics but also had much fun doing so.

The play will be presented on Tuesday 30 August 2005 and Wednesday 31 August 2005 at 10:00 and 19:00 in the Albert Wessels Auditorium on the UFS campus. Entrance is free of charge. For bookings, please contact (051) 401 2561.

On Thursday 1 September 2005 the play will be presented at 10:00 and 19:00 at the Sterrewag Theatre on Naval Hill. Tickets are R10 per person for the 10:00 show and R30 per person for the 19:00 show and are available from PACOFS booking offices or by calling (051) 447 7772.
