SA animal population genetically more diverse than Europe

South Africa is one of the greatest places on this planet to study mammals. These are the words of Prof Frank Zachos, newly appointed affiliated Professor in the Department of Genetics at the University of the Free State (UFS). 

He is also the curator of the Mammal Collection at the Natural History Museum in Vienna, Austria, the editor of the Elsevier journal Mammalian Biology, and author of several books, including Species Concepts in Biology. 

During a visit to South Africa, Prof Zachos addressed a group of UFS staff and students on the topic, ‘Conservation biology and genetics on two continents – case studies from mammalogy and ornithology’.

Inbreeding and deformities 

According to Prof Paul Grobler, Head of the UFS Department of Genetics, Prof Zachos has much experience in conservation biology studies. A large part of his work is on the population/conservation genetics of mammals (particularly deer) and, to a lesser degree, birds. Among others, he has studied red deer and the alpine golden eagle and has previously collaborated with Prof Grobler on projects involving local impala and gemsbok populations. 

Prof Grobler explains: “Typical conservation genetics studies helps one understand whether it's genetically going well with a species or population or not. This information can then be used to decide whether to move new animals to a population to prevent loss of genetic diversity.”

In his lecture, Prof Zachos explained the genetic diversity of red deer across Europe, and how this was influenced by past events (glaciers), but also by current anthropogenic factors (motor highways). 

He said there are several similarities between the mammals and birds of Europe and South Africa. The area south of the Sahara, however, is more of a biodiversity hotspot, unlike most areas in Europe where there is often lower genetic diversity in certain species. European deer species, for instance, are inherently less genetically diverse than antelope.

“Small population sizes can result in inbreeding. In some animals, this can result in deformities such as a shorter lower jaw or calves born without eyes,” said Prof Zachos.

Tracing geographic origin

With information on the gene diversity of a population of animals, authorities can implement preventative measures to address inbreeding, e.g. building green bridges to connect populations.

Population/conservation genetics studies are also helpful to determine which animals from a certain population are native to a specific area. Prof Zachos was involved in a study for the Belgian government, tracing the geographic and genetic origin of the country’s red deer. 

He said the ideal is to have genetic information for every population for management applications. 

During his visit, Prof Zachos also visited the Doornkloof Nature Reserve, since he is co-supervising a PhD student in the UFS Department of Genetics, who is based at Doornkloof.

Research at the University of the Free State (UFS) has indicated that nearly 60% of students are victims of food insecurity and suffer from hunger most of the time. The research by the UFS Faculty of Health Sciences shows that a further 25% are food insecure but are not hungry most of the time.

Senior Lecturer in the Department of Nutrition and Dietetics, Dr Louise van den Berg, says food insecurity is common among student populations across the world. However, local research shows that it is almost double that of tertiary institutions in developed countries.

Food insecurity among students caught many people off-guard
Dr Van den Berg says in South Africa nobody had really looked at the problem until recently “It seems student food insecurity has caught many people off-guard.” She says people tend to think of tertiary students as a privileged group.

The research has now indicated how deep the problem really is on campus. The students that most likely go hungry are single, male, black or coloured, and are generally first-generation students.

They are also mostly undergraduates, those paying their studies from non-bank loans or bursary means, those not living with their parents or guardians or those that need to support somebody else financially.

The results further indicate that those that are likely to suffer from hunger seldom or never have enough money for food but have to borrow money for food, have to ask for food, sell items to get food or steal food.

“A healthy student is a
successful student.”

Bursary money send back home for parents to survive
Dr Van den Berg agrees that one of the main reasons for the situation is economic stress. Research has shown students rarely spend money on food when resources are scarce. Furthermore, parents of students studying with bursaries are not always able to fully support them on campus. Some students send bursary money back home for their parents to survive.

She says other factors that contribute to campus food insecurity are that all over the world universities have terminated catered food halls due to high costs. “To a large extent this has created a food desert for students and now they need to look after themselves.”

To throw money at the problem does not seem to be the answer. 

Students are food-uncertain beings
The research indicates that young people on campus do not know where to buy food, much less the correct, nutritional food they need. Dr Van den Berg says most universities are now aware of the problem and have been taking steps. This includes teaching students how to budget and making them aware how important nutrition is for their success and their responsibility for themselves.

Universities are also looking at private funding for food aid and food schemes. Dr Van den Berg says other solutions are the restructuring of bursary fees, student self-help initiatives and food gardens.

The Faculty of Health Sciences is taking the initiative to manage a food blog on the UFS website. It will also use other social media platforms to post food-preparation videos and recipes for students.

Dr Van den Berg says it is important to grow the 15.6% group of students who indicated they are food secure because a healthy student is a successful student.
