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.”

UFS Centenary ends with a weekend of festivities

2005-02-04

The University of the Free State ’s (UFS) Centenary celebrations will come to an end this weekend with a packed programme.

“We celebrated this momentous milestone of the UFS since 28 January 2004 and want to end the year on a high note,” said Mr Jan Ras, Centenary Coordinator.

The weekend will start on Friday 4 February 2005 when Prof Frederick Fourie, Rector and Vice-Chancellor, will open the UFS officially. This will be followed by an historic photo of all staff and students who are on campus that day. All staff will be wearing their academic gowns and the Centenary emblem will be depicted.

The annual Kovsie Engen Rag, with We thank you South Africa as theme, will take place on Saturday 5 February 2005 . The procession will start at 08:00 from the UFS Kovsie church and will move down Nelson Mandela Drive and right into Markgraaff Street exit until it reaches St Andrew’s Street. From here it will turn right into Kings Way where it will stop at the Art Market at 10:00 . Prof Frederick Fourie will then propose a toast on the procession. Afterwards the groups and orchestras will step out and the floats will move through the center of town around Hoffman Square and then back to the UFS campus.

According to Mr Ras a reunion for the Student Representative Council (SRC) will also take place this weekend. About 100 former SRC members are expected to attend the planned activities.

The weekend will be concluded on Sunday 6 February 2005 with a special service of devotion, hosted by all the interdenominational groups on the campus. The service starts at 18:00 for 18:30 in front of the Main Building of the UFS and will be a celebration of praise, thanks and worship, followed by a message from Dr Wollie Grobler. The evening will be concluded with a mass choir and a fireworks display.

“Members of the public are welcome to attend the service of devotion and are requested to bring a candle for the purpose of the mass choir. Although chairs will be arranged in front of the Main Building , people are requested to bring extra pillows and blankets to sit on,” said Mr Ras.
