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.”

Transformasie-resep

DIE transformasieproses in Suid-Afrika kan vooruitgang pootjie as dit nie reg aangepak en deurgevoer word nie.
 
 

Anders gestel: 'n Onbekookte, ondeurdagte proses kan soveel skade aanrig dat dit die land jare gaan neem net om weer op die been te kom.

 
 
Dit is hierdie slaggate waarteen prof. Adam Habib, direkteur van demokrasie en regering by die RGN, waarsku. Transformasie in die hoër onderwys is hier ter sprake, maar belangrike lesse is ook vir die res van die staatshuishouding te leer.
 

Habib het op 'n gespreksgeleentheid op die Wits-kampus gesê universiteite kan binne 10 tot 15 jaar sterf as niks gedoen word om nuwe, jong akademici van gehalte te werf nie. In hul poging om te transformeer en "swart boude op sitplekke te kry" het universiteite so agtergeraak met hul doelwitte dat hulle nou selfs van swakker gehalte is as vroeër. "Speletjies" word met transformasie gespeel en 'n "malheid" rondom syfers is aan die gang.
 

Instellings fokus so daarop om hul kwota-mikpunte te bereik, sê die professor, dat dienslewering en kundigheid die kreeftegang gaan. "So kry 'n mens 'n situasie waar die adjunk-president dan aankondig sy moet Indië toe gaan om vaardige mense te kry."
 

'n Mens kan net hoop dat hierdie waarskuwings op die regte ore val.
 

Transformasie is nodig, maar beslis nie tot elke prys nie.
 

Dit kan die hoëronderwys-sektor loon om te kom kyk waarheen die Universiteit van die Vrystaat met sy Institusionele Manifes op pad is.
 

Die manifes, tans nog 'n besprekingsdokument, gaan die transformasieproses van die UV rig met as einddoel 'n instelling waar alle Suid-Afrikaners plek sal hê en tuis sal voel, maar waarin kernwaardes soos akademiese gehalte en die volgehoue versterking van kernbevoegdhede en -vermoëns ononderhandelbaar is.
 

Dit is sekerlik die enigste pad na transformasie-welslae wat Suid-Afrika kan en moet loop.
