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.

UFS History lecturer becomes Visiting Fellow at Harvard

Prestige Scholar and lecturer of African/South African History at the UFS, Dr Chitja Twala, was recently accepted as a Visiting Fellow at the Harvard Graduate School of Arts and Sciences (GSAS).

A Visiting Fellow status is available to individuals holding a doctoral degree to pursue independent research at Harvard. The Fellowship is for non-degree purposes but aims at the enhancement and further intellectual development of those involved. It focuses on enrichment and development programmes.

Twala was appointed in the Department of History at the UFS in the beginning of 2003. His research field is Liberation History, with specific reference to the liberation movements on the SADC region. He has published extensively on this field and presented papers in local and international conferences.

“I applied (to Harvard GSAS) in April 2014 for the Fellowship through the South Africa Harvard Fellowship Programme,” says Twala.

“After being successful in the interviews conducted by the GSAS panel in July 2014, I had to apply for admission in the Department of African and African American Studies at Harvard, and got accepted for the Fall Semester of 2015.”

At Harvard, Twala will be mentored by Prof Emmanuel Akyeampong (African History Expert).

“Firstly, my main assignment will be to grasp a much deeper theoretical knowledge/framework in historical studies and a broader repertoire of methodologies in the field of African History. Secondly, if time permits, I will be presenting seminars and attending some in a very challenging, stimulating, and intellectually demanding environment where my ideas can be tested and expanded. Thirdly, I will be exposed to new trends as far as African historiography is concerned. Lastly, I will informally engage and exchange some ideas with some experts in the field of African History.”

The programme was recommended to Twala by the Vice-Chancellor and Rector, Prof Jonathan Jansen and Prof Ian Phimister, Centre for Africa Studies Senior Professor at UFS.

“As per the priorities of the Prestige Scholarship Programme, the Fellowship will assist in inculcating in me the intellectual breadth and depth required to pose critical questions and generate ground-breaking knowledge for History as a discipline. It is important for the UFS to establish and sustain international networks with other leading universities and scholars around the world.

“I applied for this Fellowship in order to advance further and broaden the scope in the three areas of scholarship in higher education: discovery, teaching, and public engagement,” says Twala.

Twala will be leaving for Harvard by mid-August and will return by the end of December 2015.
