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.”

University community join hands in the walk for peace and justice

2016-03-02

The Campus Ministries Forum and South African Council of Churches (Free State) have organised a walk for peace and justice from the Main Building to the Callie Human Centre on the Bloemfontein Campus of the University of the Free State (UFS) on Tuesday 1 March 2016. This walk was followed by a prayer meeting at the Callie Human Centre.

Pastors from the Campus Ministries Forum of the South African Council of Churches (Free State) led a group of more than 350 students and staff in praise and worship, followed by prayers in English, Afrikaans, and Sesotho.

A significant gesture at the event was the church leader’s plea for peace and solutions for the conflict at the UFS.

Bishop Monty Mabale, Chairperson of the South African Council of Churches, read an extract from the declaration compiled by the pastors ministering to staff and students at the UFS.

“We are saddened by the violence and vandalism that took place on and off campus. We understand that there are many reasons for frustration and anger, which lead to tensions at the end of last year and again now. We also understand that there are different perspectives on these developments and the complexities underlying to this. However, we cannot agree with the hate speech, the continuous blaming of others, the instigation of violence, and the damage being caused to this precious institution and its commitment to the ideal and practices of reconciliation and a proper education for every student.

“Because we believe in the justice and mercy of God in Christ, let us seek His justice in a compassionate way. Let us resolve to glorify his name in the way we enter into dignified discussions when addressing those matters we perceive to be injustices, and seek for solutions. Let us be critical of our own biased perceptions, opening ourselves to the practice of listening to the viewpoints of others and learning from each other, while discerning the will of God in our society together,” Bishop Mabale said.

The forum and council also wrote a special prayer for UFS students, staff, parents, and management:

Our Father in Heaven
•   You have created us all as unique, special people, each with a great destiny.
•   You have an awesome plan for our University, and value every person working and studying here.
•   We have not respected Your heart and opinion of everyone on campus, and so we have sinned against You.
•   Forgive us where we did not follow Your example of reconciliation, restoration, and forgiveness through the blood of Christ, Your Son, on the cross. We need You to show us what You expect of us: grace, mercy, respect, and tolerance for one another from a place of gratefulness and humility.
•   We are grateful for the opportunity and honour You have given us to be involved in this institution.
•   We repent and accept afresh Your commandment to love You and to love our neighbour as we love ourselves.
•   You are saying to us: “For I know the plans I have for you," declares the LORD, "plans to prosper you and not to harm you, plans to give you hope and a future.” We, as an institution, believe and receive this promise You gave to us.

In Jesus Name we pray,
Amen.
