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.

Kovsies present case studies to Tata Africa
2014-04-15

Tata Africa welcomed four top scholarship winners from the University of the Free State’s (UFS’s) Business Management Department who were awarded academic bursaries in 2013 for developing practical marketing strategies for the Tata group companies as part of their studies.

The students presented their winning case studies to a panel of Tata Africa executives and senior managers in Johannesburg.

“The Tata group places social responsibility at the core of its business DNA. This kind of support characterises our commitment to communities where Tata companies operate worldwide,” said Thami Mbele, Managing Director for Tata Africa Holdings.

“The impressive work of the Strategic Marketing students of the University of the Free State’s Business Management Department, who have been using Tata group companies as examples for their practical marketing strategies, deserve recognition,” he added.

To date, Tata has invested R275 000 in the University of the Free State’s talent pool. Over the past six years, Tata Africa has invested over R10 million in scholarships in Africa.

Second-semester students of the Strategic Marketing course, Lebohang Masoabi, Estie Brown, Lynne Harvey and Cecile Boshoff, were given a rare opportunity to apply their theoretical knowledge by developing practical marketing strategies for Tata group companies operating in Africa. Students presented their ideas to a panel of UFS and Tata representatives in 2013, and 27 out of 78 groups were selected to compete for academic bursaries sponsored by Tata.

Through its scholarship programme, Tata Africa is committed to investing in future African entrepreneurs, leaders of industry and business.
