The research team helps a giraffe to get up after they have finished collecting data.

Researchers from the University of the Free State (UFS) hope their research to investigate why some animals prefer or avoid some habitats, will also create awareness for the plight of giraffes which have lost more than 80% of some of their subspecies in East Africa and are facing extinction in the wild.

Dr Marietjie Schutte-Smith, Senior Lecturer in the Department of Chemistry, says the collaborative research being done in South Africa is very unique and could help save subspecies from the brink of extinction – as South Africa has managed to double its giraffe numbers whilst subspecies have declined tremendously.

Why some animals prefer or avoid some habitats

“By using modern analysis techniques and instruments (such as drones and GPS devices), it is possible to study complex environments on a spatial ecology scale and has created the opportunity to investigate why some animals prefer or avoid some habitats,” explains wildlife expert Dr Francois Deacon.

“This in turn opened the door to explore geographic, soil and nutritional qualities the giraffe might prefer or avoid. This is one of the main reasons we are exploring the different factors and driving forces behind a large herbivore’s habitat selection, well-being, body condition parameters and physiological adaptations,” Dr Deacon says.

Veld conditions, plant species composition, tree densities and other available resources such as production yield and water quality determine reproduction successes and how animals disperse, move and distribute over an area. Spatial and ecological distributions of giraffe specifically depend on habitat resources and qualities that in turn affect their complex behavioral tactics and survival.

Strange habits

The research was started back in 2010 by Dr Deacon and Prof Nico Smit from the Department of Animal, Wildlife and Grassland Sciences at the UFS with the pioneering of GPS devices to investigate giraffe spatial ecology and habitat use. The current study was initiated as to why the giraffe would utilise one area more than the other, even if the two habitats had the same tree species, says Dr Schutte-Smith.

Dr Deacon contacted Prof Hendrik Visser and Dr Schutte-Smith from the Department of Chemistry for a possible collaborative effort. Ms Jeaneme Kuhn started her MSc research degree on this project in January 2019 and completed her degree in August 2020 with distinction.

Dr Schutte-Smith says from research done at Rooipoort Nature Reserve it was found that a certain group of giraffes had the strange habit of only eating from specific trees, avoiding similar trees a few metres away. “We wanted to see if this behaviour was due to chemical influences, i.e. if there are specific minerals that are possibly in excess at some places which they avoid, especially since there are mines close by.”

Aim of the research

The main aim of this MSc Chemistry degree, according to Dr Schutte-Smith, is to validate an analytical method for testing leaves and soil samples, using IPC, to see if heavy metals (in excess) are present in the soil, leaves and water and whether this has an influence on the browsing pattern of the giraffes. “Then as secondary aims (for the collaborative effort) we would like to investigate if the giraffe can select one area above the other (core home ranges), to understand what the qualities are that they would select for in the preferred area and what the qualities they avoid are in the other. And lastly to understand what the minimum requirements are to keep the animals happy and healthy, but also to investigate how they search for these qualities,” says Dr Schutte-Smith.

Giraffe conservation

Besides creating awareness of the plight of giraffes, the researchers also aim to create a model for conservation via research and education to be used as an example for other countries. This model incorporates students, academia, professionals, sponsors and stakeholders that cover various topics relating to giraffe education, management and conservation.

They would also like to see the UFS as the institution that has contributed the most to giraffe conservation strategies in Africa by being the leading university in the collection and analysis of information about giraffes and their habitats, increasing conservation education awareness about giraffes and African biodiversity and to develop national and/or regional plans aimed at giraffe conservation.

The research team successfully applied for funding which they used for chemicals and solvents to perform testing as well as sampling.

NRF commits R30-million for research at the UFS
2007-02-20

The National Research Foundation (NRF) has committed approximately R30-million for various research projects at the University of the Free State (UFS).
 
According to Prof Frans Swanepoel, Director of Research Development at the UFS, the NRF has also approved all eight research niche areas that were submitted to the NRF, the highest number approved at any university in the country.
 
Prof Swanepoel said the 24 research projects for which funding had been obtained from the NRF ranged from traditional healing and HIV/Aids/tuberculosis management, practices of the paediatric anti-retroviral programme at the UFS to nano-materials synthesis and characterisation.
 
He said the eight research niche areas were part of an initiative at the UFS to establish strategic clusters of academic and research excellence.
 
“There will be six strategic academic clusters at the UFS and the eight NRF-approved research niche areas will form part of them,” Prof Swanepoel said.
 
The six strategic clusters are:
1.         Water management in water-scarce areas
2.         New frontiers in poverty reduction and sustainable development
3.         Social transformation in diverse societies
4.         Ecologically sound value chains for agricultural commodities
5.         Materials and nano sciences
6.         Advanced bio-molecular research
 
Prof Swanepoel said that the UFS had also submitted five proposals in terms of an NRF initiative to establish research chairs at South African universities.
 
“Linked to our intention to establish six strategic academic clusters, five proposals for the South African Research Chair Initiative (SARCHi) were submitted. All five pre-proposals were accepted in the first round of screening, and successful candidates have been invited to submit full proposals by the end of February,” he said.
 
The proposed research chairs are:
 
Petro- and organometallic chemistry
Biocatalytic and biomimetic oxidation-reduction systems
Nano-solid state lighting
People’s health and well-being
Water management
 
Speaking at the official opening of the university earlier this month, the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie, said: “The cluster initiative represents a strategic initiative to focus our energies in a few key areas, investing in them so that the UFS can become an international leader in those fields.”
 
“A medium sized university such as the UFS with relatively limited human, physical and financial resources has to achieve this kind of ‘critical mass’ and synergy to establish itself in terms of its core functions of teaching/learning, research and community engagement,” said Prof Fourie.
