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.

SA cannot sustain momentum - Boesak

South Africa finds it increasingly difficult to live up to the challenges facing it as a nation because of its failure to meet its democratic ideals and possibilities, peace and lack of self-belief.

This was according to renowned cleric and former political activist, Dr Allan Boesak, who recently delivered the CR Swart Memorial Lecture, the oldest memorial lecture at the University of the Free State (UFS). His lecture was on the topic Creating moments, sustaining momentum.

He said South Africa had plenty of opportunities to show the whole world what was possible if all the people of this country joined hands and worked together to build a truly united society. However, he said, the country somehow invariably contrived to find its way out of these wonderful possibilities.

He cited events of historical significance like Codesa, the inauguration of Nelson Mandela as the first democratic president of South Africa, the assassination of South African Communist Party leader, Chris Hani; and the rugby and soccer world cups.
To drive his point home about this dismal failure of the country to “sustain momentum”, he alluded to the current public servants’ strike that is gradually crippling public service.

“The public servants’ strike was neither unexpected nor is it completely unjustifiable. Most of us have understanding for the frustration of teachers and health workers. Their demands resonate with most of us, and I think that it is scandalous of SACP fat cats to tell workers to “stop crying like babies,” he said.

He also added to the criticism of the much-maligned decision of the government to spend billions of taxpayers’ money to purchase weapons when there was “no discernible military threat” to the country. He said the greatest threat to the security of the country was poverty, inequality and social cohesion.

“As for the argument that arms sales bring in foreign exchange – how can we be instrumental in killing the poor elsewhere with the intention of feeding our poor, and then our ill-gained profits feed only the already well-fed?” he asked.
“Can we see the hopeless contradiction, the total impossibility of being both the apostle of peace and a merchant of death?”

He also lambasted the Black Economic Empowerment (BEE) policy of the government which he said benefited only those connected to the political aristocracy.

“It couples with the unashamed, in-your-face display of wealth by the privileged elite in this country, the crass materialism of the so-called “bling generation”, and the casual carelessness with which promises to the poor are given and treated. It is only the public symptom of the deep-seated scorn our political elites feel for the poor,” he said.

He said the government’s disdain to the poor was “setting fire to our future”.

“The anger of people on the ground can no longer be denied or ignored, and little by little, the leadership articulating and directing this anger is being estranged from politically elected leadership, and even more disturbing, from our democratic processes,” he said.

He concluded that the country’s difficulty in dealing with race and racism was putting the reconciliation process kick-started by Mandela just over a decade ago, under a threat.
