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.

Universities join hands in developing literacy tests

The development of academic literacy tests recently took a step into the future with the formal establishment of the Inter-institutional Centre for Language Development and Assessment (ICELDA).

ICELDA, under its first executive head, Prof. Albert Weideman, Head of the Department of English at the University of the Free State (UFS), is a cooperative venture between the multilingual Universities of Pretoria, North-West, Stellenbosch and the Free State.

It is dedicated to the development of reliable state-of-the-art academic literacy tests and currently makes 32 000 tests available to partnering universities annually.

Most notably, it has produced three of the most reliable academic literacy tests in the country. These include an Academic Listening Test and the Test of Academic Literacy Levels (TALL) for undergraduate students, with reliability levels that are more than 20% above international benchmarks.

“We are even more excited about our Test of Academic Literacy for Postgraduate Students (TALPS), which is already a crucial instrument in determining the literacy levels of postgraduate students at the Universities of the Free State, Pretoria and North-West,” said Prof. Weideman.

In addition, ICELDA is currently piloting studies for language tests for financial advisors, nurses, students of disaster management, as well as police studies at Unisa.

ICELDA will also collaborate with the Centre for English Language Communication (CELC) at the National University of Singapore.

“One of the undertakings I made on my visit to Singapore a year ago was that I would assist in every way I could with the building of joint expertise with CELC in language testing,” said Prof. Weideman.

“However, our focus will remain firmly on research.”

He said his goal was to employ the surpluses generated by selling tests to provide promising students with bursaries to stimulate further study and design of academic literacy and other language tests.

By drawing more researchers into the field, Weideman said, ICELDA could provide the capacity for developing reliable language tests that South Africa had always lacked.
