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.”

Louzanne to represent South Africa at World Championship

2015-10-26

Within the space of seven days, Louzanne Coetzee will take part in both the 1500m and 800m events at the International Paralympic Committee (IPC) Athletics World Championships, being held in Doha, Qatar, from 21-31 October 2015.

The BA Corporate and Marketing Communication Honours student at the University of the Free State (UFS) was selected to represent South Africa (SA) by the South African Sports Confederation and Olympic Committee (SASCOC). Team SA consists of 23 top athletes, who will be competing in different codes against 89 other countries.

The middle- and long-distance T11/F11 class athlete has won countless medals since her debut in professional athletics in 2012. After only five months, she reached the qualifying standard for international participation, with an impressive 2 minutes 53.8 seconds in the 800m at the 2013 Nedbank National Championships for the Physically Disabled, held in Pretoria.

Louzanne has since achieved another international milestone by making the SA team, following her inaugural IPC meeting, hosted by France two years ago.

“It’s a big honour for me to represent South Africa, and I count myself very fortunate to represent the country at the World Champs,” said the former Accessibility and Student Support Student Representative Council (SRC) member.

The IPC World Championships precede the Rio 2016 Paralympic Games, which are known as “the biggest sporting event on the planet”. Qatar is Louzanne’s Rio, and she intends to outdo her personal best in order to qualify. “I want to get my ranking high enough so that I can go to Rio in 2016,” said the gold medallist.
