Prof Frank Zachos
Prof Frank Zachos recently delivered his inaugural lecture on the UFS Bloemfontein Campus.

Prof Frank Zachos, a scientist and Head of the Mammal Collection at the Natural History Museum (NHM) in Vienna – one of the world’s largest natural history museums – recently delivered his inaugural lecture at the University of the Free State (UFS) on the Bloemfontein Campus.

His lecture was titled: Of bat bombs and super moms – the wondrous and wondrously curious world of mammals.

Prof Zachos, an affiliated researcher at the UFS, says he chose mammals as the topic of his lecture because he is a mammalogist and curator of mammals at the Natural History Museum. Additionally, he collaborates with Prof Paul Grobler, Head of the Department of Genetics, on mammal projects.

Exposure to almost unparalleled biodiversity in SA

With a mixture of entertaining fun facts and some proper research results, he presented his lecture, providing an overview of some of the most interesting aspects of mammals. These included their different ways of reproduction: the platypuses laying eggs, the tiny marsupial offspring growing in a pouch, and placental mammals having long gestation times. Furthermore, he compared levels of biodiversity in South Africa and Europe and highlighted some particularly bizarre mammals, such as the aye-aye, naked mole-rat, the platypus, and two extinct South African ungulates from their collection in Vienna – the quagga and the blue antelope.

Prof Zachos also discussed his own research on blue antelope genetics, as well as research on other species, in the context of the detrimental impact humans have on mammals and other wildlife.

Moreover, his lecture included a reference to Project X-Ray, a story of how the US army pursued an unsuccessful plan to use bats as carriers of mini bombs in World War II.

Prof Zachos, who is specifically known for his research on the systematics, biogeography, and genetics of red deer, as well as his theoretical work on the species problem (‘what is a species?’ –  one of the most hotly debated topics in evolutionary biology), is affiliated with the UFS due to his longstanding collaboration with Prof Grobler. He says they have known each other for a long time, have published together, and that he has also served as an external reviewer for several theses coming from the Department of Genetics.

“Apart from this personal connection, what made this collaboration particularly interesting to me from a professional viewpoint, is the rich wildlife biodiversity and the research focus of Prof Grobler’s research group, which overlaps significantly with my own longstanding interests,” adds Prof Zachos.

“Working with Prof Grobler, I am involved in studies on the genetic diversity and structuring of different mammal species occurring in South Africa. The opportunity to spend time in the field for sample collection and other activities is definitely also a highlight,” remarks Prof Zachos.

Ideal combination of academic and personal growth

Regarding his connection with the UFS and its impact on shaping the future direction of his research, he states that he has a strong interest in antelopes – a group of mammals not found in Europe, but very prominent in South Africa. “Apart from that, people in the Department of Genetics have expertise in relevant areas that I personally do not have, for example bioinformatics. For me, it is the ideal combination of academic and personal growth, and I am very grateful to have this unique opportunity.”

He believes that his affiliation with the UFS and its Department of Genetics will continue to provide him with opportunities to expand his research and knowledge to different species and ecosystems.

Beyond science, he says that he has developed an interest in the country as well. “I have been reading books about South Africa, and I consider myself very privileged to have a second academic home here, which gives me the opportunity for exchange with people of different backgrounds,” he comments.

Researchers reach out across continents in giraffe research
2015-09-18

Dr Francois Deacon and Prof Fred Bercovitch
busy with field work.

Researcher Dr Francois Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State is conducting research with renowned wildlife scientist, Prof Fred Bercovitch, from the Center for International Collaboration and Advanced Studies in Primatology, Kyoto University Primate Research Institute in Japan.

Dr Deacon’s ground-breaking research has attracted international media attention. Together with Prof Nico Smit, he equipped giraffes with GPS collars, and conducted research based on this initiative. “Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.”

Prof Bercovitch was involved with GPS tracking from elephants to koala bears.

Some of the highlights of the joint research on giraffes by Dr Deacon and Prof Bercovitch focus on:
 
• How much time do certain giraffes spend with, and away from, one another
• How do the home ranges of herds and individual giraffe overlap
• Do genetically-related animals spend more time together than non-genetically-related animals
• How much time do the young bulls, adult bulls, and dominant bulls spend with cow herds
• Herd interactions and social behaviours of giraffe
• The role of the veld and diet on animal behaviour and distribution

 

Their research article, “Gazing at a giraffe gyroscope: Where are we going?”, which was published in the African Journal of Ecology, assesses recent research by exploring five primary questions:

- How many (sub) species of giraffe exist?
- What are the dynamics of giraffe herds?
- How do giraffe communicate?
- What is the role of sexual selection in giraffe reproduction?
- How many giraffe reside in Africa?

They conclude this article by emphasising that the most essential issue is to develop conservation management plans that will save a wonderful species from extinction, and which will also enable scientists to conduct additional research aimed at answering their five questions.

In addition, they are working together on a grand proposal to get National Geographic to cover their work.
