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.”

Breakfast in aid of hungry students

2011-06-01

Our university again proved that it cares for the welbeing of its students when a sum of money was presented to the No Student Hungry Project during a breakfast function.

The Centre for Health and Wellness at the UFS organised the event, not only to introduce the scheme to staff and individuals and thank those concerned for their contributions, but also to present the project organisers with a donation of R50 000. Mrs Grace Jansen, wife of Prof. Jonathan Jansen, Vice-Chancellor and Rector and Dr Carin Buys, wife of Mr Rudi Buys, Student Dean, started the project this year after a study found that 20% of students at the UFS have to study on an empty stomach and that this often leads to students leaving the UFS prematurely.

Ms Tanja Malherbe, mistress of ceremonies, said that the project is blessed because it developed from the founder members’ love for the students. The project currently provides 6 000 deserving students with a meal per day.

Prof. Jansen said that although the university encourage academic success, the UFS is also ready to show its mettle on a humanitarian level. “We don’t want students to only study together, but also to eat together.” He added that food can promote a feeling of fellowship, gives comfort and is also a symbol for caring. “It is bad to be hungry, no matter what the colour of your skin. Especially when other people have food and you don’t.”He concluded by saying that we are blessed by giving to other people, and by giving, we also receive.

Ms Tarryn Nell, also from the centre, supported him by comparing caring to candlelight. “It drives the darkness away, involves compassion and gives direction. When two people can get things to change, the rest will follow.” She encouraged the audience to share their warmth, time, knowledge and resources with other people.

During the event, a picture summary also referred to two recent projects the centre hosted. The first was a free medical screening test for staff members and the second a temporary remembrance rose garden, representing the five main causes of deaths in the country. These causes are HIV, ischemic heart disease, stroke, tuberculosis and interpersonal violence.

The proceeds from Prof. Jansen’s book “We need to talk,” will be donated to the project. Persons wishing to make a contribution, can make a payment to the following account: ABSA 157085 0071, reference number 146 674 604, account number 0198, branch code 632 005. Deposit slips can be sent to pelserr@ufs.ac.za.
