SA animal population genetically more diverse than Europe
The Department of Genetics appointed the curator of the mammal collection in Austria’s Natural History Museum, Prof Frank Zachos.

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.

Wayde one of the Adidas faces for Rio 2016

Wayde van Niekerk has not only been nominated for two awards at the SA Sports Awards. He will also be one of the Adidas world ambassadors for the 2016 Olympic Games in Rio de Janeiro.

Wayde van Niekerk’s face may already adorn billboards at Pellies Park on the Bloemfontein Campus and other places around the University of the Free State, but it will now also be used for marketing campaigns worldwide.

The Kovsie athlete will be one of the Adidas world ambassadors for the 2016 Olympic Games in Rio de Janeiro. Adidas is sponsoring him.

According to a modest Van Niekerk, he has been with the clothing sponsor since 2010, and it is a great honour to be an ambassador for the Olympics in Rio

Other awards

After a dream year, being an Adidas ambassador is the latest honour to come his way.

He was also nominated for two awards in the SA Sports Awards, which will be held in the Sand du Plessis Theatre in Bloemfontein on Sunday 22 November 2015. He was nominated as Sportsman of the Year and in the People’s Choice category.

On 21 October 2015, Van Niekerk was named KovsieSport’s Sportsman of the Year for a third consecutive year.

He was recently also honoured at the Free State Schools Athletics Association’s Gold Medal event.

A world superstar

Van Niekerk says it’s good to be part of the legacy Adidas is building as a company.

“It is exciting for me, knowing that I am selected among such great athletes (being an Adidas ambassador), and not just South African athletes, but world athletes,” he says.

“It is the likes of the top Adidas athletes that are going to represent the company and be ambassadors for the company.”

“It is something I am looking forward to – being on posters and seeing my face on billboards and advertisements.”
