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.”

Lecture honours one of SA’s greatest women leaders

2008-08-22

A member of the national executive committee of the ANC Women’s League, Yolanda Botha, has called on all South Africans to cherish the legacy of Charlotte Maxeke, one of South Africa’s greatest women leaders.

Ms Botha was delivering the first Charlotte Maxeke Memorial Lecture at the University of the Free State (UFS) in Bloemfontein last night, in honour of the pioneering role played by Maxeke in the struggle for human rights, democracy and freedom. The lecture series is a partnership between the Free State Provincial Government and the university.

She was born Charlotte Makgomo Manye on 7 April 1874 at Ramokgopa in the Polokwane district in Limpopo. In 1905 she graduated from the Wilberforce University in Ohio in the USA with a B.Sc. degree, making her the first black South African woman to graduate with a science degree.

She married the Rev. MM Maxeke, a prominent AME minister who had also been educated overseas, and together they collaborated on the compilation and publication of the first AME church hymn book in Xhosa.

Later she became a founder member and president of the Bantu Women’s League, forerunner of the ANC Women’s League. She was an early opponent of the pass laws for black women and an organiser of the anti-pass movement in Bloemfontein.

Charlotte Maxeke died in 1939. Two years later, an ANC conference held in Bloemfontein, passed a “resolution on the women’s section”.

Elaborating on the challenges that women still face, Ms Botha said poverty remains a challenge affecting the majority of women. She called on all women to unite and engage with government to develop a comprehensive strategy for food security and agricultural support programmes to eradicate poverty.
