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.”

Greyhound racing: Public input needed

2009-02-03

Members of the public have a second opportunity to make submissions regarding the possible legalisation of greyhound racing in South Africa.

A research team from the Faculty of Law at the University of the Free State (UFS), in conjunction with the Department of Trade and Industry (dti), will hold a second round of public consultations in Gauteng, the Free State, North West, the Eastern Cape, the Western Cape and KwaZulu-Natal in February and March this year.

During the first round of consultations last year the research team, under the supervision of Prof. Elizabeth Snyman-Van Deventer of the UFS, received written submissions from interested members of the public and various associations.

The purpose of this research project is to give an objective overview of the greyhound racing industry nationally as well as internationally. This includes aspects such as animal welfare, social, economical and political issues and the legal framework pertaining to greyhound racing.

The study focuses on the current situation in South Africa and internationally regarding the jurisdictions where the sport is currently active and the current legal framework.

It will also include a comparative study of the situation in countries such as the United States of America, Ireland, England, Belgium, Australia, New Zealand, Canada and Vietnam.

Greyhound racing was banned in South Africa years ago because gambling was regarded as immoral at that time. Now that gambling has been legalised and is regulated there are debates on the legislation of greyhound racing.

The animal welfare and protection groups are against the legalisation of greyhound racing, while other role players have been calling for the racing to be legalised and regulated.

The public consultations will take place as follows:

• 6 February 2009, 09:00-12:30, Protea Edward Hotel, Durban
• 13 February 2009, 09:00-12:30, Protea Sea Point Hotel, Cape Town
• 20 February 2009, 09:00-12:30, Protea Marine Hotel, Port Elizabeth
• 26 February 2009, 09:00-12:30, Garden Court Hotel, Bloemfontein
• 27 February 2009, 09:00-12:30, Protea Manor Hotel, Hatfield, Pretoria
• 6 March 2009, 09:00-12:30, Garden Court East London, Esplanade, East London
• 13 March 2009, 09:00-12:30, Willows Garden Hotel, Potchefstroom

For further information, members of the public who are interested in attending these consultations should contact Mpho Mosing of the dti at 012 394 1504/083 436 5534 or Prof. Snyman-Van Deventer at 051 401 2698 or e-mail it to snymane.rd@ufs.ac.za
