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.”

Shimlas had the right attitude, says Scholtz

His rugby team had the right attitude to win in difficult conditions in Cape Town.

This is what Hendro Scholtz, Head Coach of Shimlas, had to say after the University of the Free State (UFS) started its Varsity Cup campaign on 8 February 2016 with a victory of 23-17 over Ikeys.

According to him, the UFS had to sweat hard until the end on a windy Green Mile, which has been the downfall of many opponents before. His substitutes also had a great impact.

Troublesome Cape wind

Shimlas have a tough draw this year, and to start in the Mother City was a huge task. Scholtz and his men have only three home matches and will play against most of the major teams in away matches.

“We knew it would be difficult in Cape Town. With the wind blowing as it does, one can't play as you would like to during the rest of the season,” the coach said.

“The guys had a will to win.”

The former Springbok believes that too much cannot be read from the first round results. The Shimlas will play their second match on 15 February 2016 against Tuks in Pretoria.

Replacements with good impact

Only the prop Rudolph Botha, flanker Fiffy Rampeta, and prop Teunis Nieuwoudt, who started against Ikeys, were involved in the 2015 final against Pukke.

Other big Shimla names, such as the prop Ox Nche, hooker Elandré Huggett, prop Conraad van Vuuren, and flanker Daniel Maartens, were sent onto the field in Cape Town after half-time.

“We had a plan with the replacements for the second half. They made a huge difference,” Scholtz said.

Rampeta was named Man of the Match, but it was Maartens and Co who turned the game in their team's favour in the second half.

Matsoele could be out of action for long

The Shimla fullback, Sechaba Matsoele, had to leave the game against Ikeys early because of a knee injury, and could be out of action for some time.

His scrumhalf, Zee Mkhabela, was also injured (by a blow to the head), so Shimlas will have to keep their fingers crossed for his quick recovery.

Scorers:
Shimlas 23 (7): Tries: Arthur Williams, Nardus Erasmus, Mosolwa Mafuma. Conversions: Stephan Janse van Rensburg (2).
Ikeys 17 (0): Tries: Khanyo Ngcukana, Nathan Nel. Conversion: Hilio de Abreu. Penalty: De Abreu.
Other results (home team first): Tuks 15, Pukke 38; UJ 19, Madibaz 12; Maties 40, CUT 0.
