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 becomes Varsity Netball champions – again

2014-10-21

Kovsies has become the first team to successfully defend the Varstiy Netball title when they beat Tuks 49-42 in the 2014 final in Pretoria on Monday 20 October.

University of Pretoria (Tuks) might have been unbeaten for the entire 2014 tournament, but this did not hinder Kovsies in becoming the Varsity Netball champions for a second consecutive time.

From the outset, both these furiously focused teams fought hard and only after ample turnovers could Kovsies finally manage to open the score board.

The Mostert sisters, Karla and Tanya, won a couple of crucial balls, leaving the UFS dominating possession in the opening exchanges.

When Tuks eventually got to scoring, they could not stop the UFS from rushing to a 9-3 lead after the first ten minutes. The visitors had established a 13-5 advantage by the first break, keeping the Pretoria crowd quiet.

The home side came back shooting in the second quarter with great determination, fighting their way back into the game. Tuks ran hard, needing to work hard against Kovsies, who still managed to be in the lead with 22-16 at half-time.

Kovsies made good use of their power play early in the third quarter to stretch their lead further to 30-22. They made the most of their opportunities, going into the final quarter with a 39-31 upper hand.

Even though Tuks made a couple of changes during the final break, they could not avoid defeat in the end.

Kovsies’ Lauren-Lee Christians was also the player of the match, while the champion’s captain, Karla Mostert, was announced as the Player of the Tournament.

This hard-working defender made a number of crucial interventions alongside her sister Tanya in the final. Karla proved that she was the fans’ tournament favorite, claiming the most votes and winning a Samsung S4.
