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 supports SAASTA in science initiative

2010-08-27

The National Astronomy Quiz for Grade 7 learners was recently hosted at the Boyden Science Centre, which is managed by the University of the Free State’s (UFS) Department of Physics. It was also Boyden and the UFS’s Department of Physics that coordinated the Free State leg of the competition. The Free State Department of Education was also on board to ensure smooth arrangements for the preliminary, as well as the first two official rounds of the competition.

The competition is hosted by the South African Agency for Science and Technology Advancement (SAASTA), an agency of the National Research Foundation (NRF).

Ninety schools from all over the Free State took part in the first official round. Eighteen schools qualified for the second round, once again with a balanced geographic coverage of the province.

During the second round, eight schools made it to the third round. Two of these schools were from Bloemfontein and the other six from other towns and rural areas in the Free State.

The third round and provincial finals took place at the Boyden Science Centre. The schools qualifying for the final round were Hennenman Primary School, Unicom Primary School (Tweespruit), Voorwaarts Primary School (Kroonstad) and Fichardt Park Primary School (Bloemfontein).

As a pleasant surprise, Unicom Primary School, a less well-known school from a smaller town, won the Free State finals. It was the first time this had happened since the inception of the competition.
