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.

Chief Justice Mogoeng Mogoeng yesterday (24 January 2013) concluded the proceedings of the first day of the International Symposium on Corruption, hosted by the Faculty of Law of the University of the Free State (UFS). In his address Justice Mogoeng made no excuses as to the magnitude of the threat corruption presents to South African citizens.

“Urgent action and efficient measures are called for to arrest this scourge, for the sake of our constitutional democracy,” he warned. “Our vibrant constitutional democracy will not and cannot survive in the face of rampant corruption.”

Justice Mogoeng said the spate of civil and labour unrest erupting throughout the country can be attributed to corruption. According to him the scope and far-reaching implications of corruption drives South Africans to “boiling point” and evokes “anger, frustration and a don’t-care-attitude that often manifests in widespread protest actions” and disrespect for the rule of law.

“South Africans, irrespective of race or creed, must identify and focus on their common enemies and find a conciliatory and unifying way of dealing with what divides them, including the lingering prejudices of the past,” Justice Mogoeng urged.

Despite the threat corruption poses, he stressed that all South Africans have a role to play in the fight against corruption and that there are different role players that can become involved in the process. Especially important is the media and faith-based agencies which, according to Justice Mogoeng, can regenerate morals and secure a “national moral code.” The State must further ensure enforcement of anti-corruption measures and preside over the selection of individuals of “solid character” to reside in agencies meant to fight corruption.

He highlighted the need for an unbiased and independent judiciary, one immune to outside influences controlled by powerful forces, as well as personal agendas.

Although Justice Mogoeng believes that the private sector is most guilty of transgressions based on corruption, he stated that a “well-coordinated war” against it must be waged in all sectors in order to stamp it out.

Justice Mogoeng presided over the unveiling of the redesigned foyer of the CR Swart Building and praised the Faculty of Law for its innovation with regard to the symposium.

“I look forward with great optimism to more well-organised symposiums that strike at the nerve-centre of the well-being of our constitutional democracy,” he concluded.

Symposium seeks answers and solutions

The Faculty of Law at the University of the Free State (UFS) concluded its International Symposium on Corruption on Friday 25 January 2013. The event featured a stellar cast of speakers, including the Chief Justice of South Africa, three current Supreme Court of Appeal judges, high-court judges, advocates, prosecutors, journalists, as well as local and international legal academics.

Throughout the two-day symposium, corruption was dissected as a severe problem in the South African socio-economic landscape and solutions were sought to alleviate the pressing concern.

The main attractions of the symposium were undoubtedly the attendance and presentations delivered by Chief Justice Mogoeng Mogoeng, as well as Prof. Leon Wessels. Prof. Wessels was described as “one of the founding fathers of the constitution of South Africa” by Judge Fritz Brand, a current Appeal Court judge and the third-longest serving judge in the country.

“Corruption is stealing the constitutional dream of this country. Corrupt leaders are fearless, those who expose corruption, are fearful,” Prof. Wessels warned.

Judge Brand closely trails the second longest serving judge in the country in former Kovsie, as well as former UFS Council Chairman, Judge Faan Hancke. Both judges addressed the symposium and chaired sessions, along with Prof. Johan Henning, Dean of the Faculty of Law, and Judge Ian van der Merwe, Chairman of the UFS Council.

It was, however, not all doom and gloom, as several of the speakers offered tangible ideas in what was often termed the “war on corruption”. Celebrated Sunday Times journalist Mzilikazi wa Afrika who has been arrested following the police leasing scandal which he exposed, urged South Africans to stand together in their fight against corruption, before it is too late.

People on the front lines in the day to day fight against corruption also spoke at the symposium, giving the audience a better understanding of the intricacies and challenges involved in the process. The Head of the National Prosecuting Authority’s Asset Forfeiture Unit, Mr Willie Hofmeyer, as well as Advocate Xolisile Khanyile, who is the Director of Public Prosecutions in the Free State, elucidated this struggle.

The symposium also hosted Prof. Chizu Makajima, a celebrated academic from the United Kingdom.

The two-day symposium ended in style as the delegates gathered in the Centenary Hall on the Bloemfontein Campus for lunch, with a further address by Prof. Leon Wessels
