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 Department of Computer Science and Informatics motivates programming success among learners
2015-04-23

A group of learners from the Free State, who are taught at and by the University of the Free State’s Department of Computer Science and Informatics (under the Python project), came first in the Talent Search round of the South African Computer Olympiad (SACO).

According to Dr Anelize van Biljon, senior lecturer in the Department of Computer Science and Informatics, the Olympiad is presented in three main rounds: the Talent Search, the Application Olympiad, and the Programming Olympiad.

At the UFS’s Department of Computer Science and Informatics’ Python project, pupils from various schools in Bloemfontein attend programming classes where they are taught by staff and students of the department. These students are benefitted by the opportunity to transfer their knowledge to others. All the classes are free of charge.

Anelize explains: “The name was chosen because we use the Python programming language. It is a language with considerable appeal – not one of the fastest – which can be learnt relatively quickly, and which conforms to SACO requirements. The purpose of this programming is to implement algorithms (the learner is given a problem, makes a plan to solve it, and does the necessary programming). Thus, it is not about the looks of the programme, but about its effectiveness and speed.”
Anelize is the initialiser and co-ordinator of the Python project. "I started this project in 2010 in the Department of Computer Science and Informatics for learners from Grades 6 to 12 to encourage them to take the subject. These classes exposed them to something more than school work. I enjoy this kind of competitions and am also very involved with Maths Olympiads.

Achievements such as these are good advertisements for the Department of Computer Science and Informatics,” she said.
