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.

Capturing 51 giraffes without any injuries or mortalities to collect data that will contribute to the conservation of these animals is not for everyone. Capturing a giraffe with minimum risk to the animal and the people involved, requires extraordinary skill, planning, and teamwork. “This exercise is a dangerous task, since a well-placed kick from these large and extremely powerful animals can cause serious injuries. Early in October was the first time that giraffes were captured on such a large scale,” said wildlife researcher Dr Francois Deacon.
 
Dr Deacon from the Department of Animal, Wildlife and Grassland Sciences at the University of the Free State (UFS), led a multispecialist research group of over 30 people from 10 different countries to collect information about these little-known animals.

UFS first to collar giraffe
Taking a global approach, the team responsible for this intricate process consisted of wildlife biologists, conservationists, interdisciplinary scientists and five specialist veterinarians who are experienced in catching and working with wild animals. Specialised drugs sponsored by Dr Kobus Raath from Wildlife Pharmaceuticals, tested for the first time and administered with a dart gun were used to tranquillise the giraffe, which then allowed for the GPS collars to be fitted.  These collars, sponsored by Africa Wildlife Tracking, enable the researchers to record the location of individual giraffe for up to two years, give 24/7 readings, irrespective of weather conditions. In this cost-effective manner, data can be gathered on climatic factors, giraffe communication, social behaviour, home ranges, seasonal movements, human and giraffe interaction zones, as well as migration routes and the duration of the migration process. The collars will effectively be used to locate individuals to collect faecal samples for hormonal cycles, stress hormones, nutrient deficiencies based on diet and also internal parasites. 

“This knowledge we gain is the key to all keys in saving this iconic animal from becoming extinct,” said Dr Deacon.

Six years ago, during a pilot study, Dr Deacon was the first researcher to fit giraffes with a GPS collar. Collaring is less invasive and allows researchers to collect detailed samples. Not only was extensive knowledge and experience gained during the process, but he also initiated interest from the filmmaker and conservationist, Ashley Scott Davison, executive producer of Iniosante Inc. 

Getting to tell the story

Davison, who was doing research for a film on giraffe learnt about the silent extinction of the species. In a great number of countries giraffe numbers have been declining by as much as 40% over only a few years since 2000. Today West Africa has between 400 to 600 giraffe left while four out of five giraffes were lost in East Africa since 2000. This is a considerable decline in numbers and poses a real threat to the survival of the species in the longer term. At the end of 2016, the giraffe was classified as vulnerable on the International Union for Conservation of Nature Red Data list.

According to Davison, children in school learn about the destruction caused by ivory poaching and habitat loss. But in Africa today, there are six times as many elephants as there are giraffes. 

In the process to find out more about this majestic species Davison learnt of Dr Deacon’s work. After being introduced to and spending time with Dr Deacon, Davison not only describes the UFS as the leader in the conservation of giraffes but he returned to the university, three times to help build a dedicated research team to address unanswered research questions within various disciplines.

Flowing from the affiliation with the UFS is Iniosante’s award-winning production of a documentary, “Last of the Longnecks”. The film has received several awards, including official selection at the 2017 Global Peace Film Festival, the Wildlife Conservation Film Festival and the Environmental Film Festival in the US capital. 

The film team accompanied the multispecialist research team last week to gather footage for a follow-up documentary, “Catching Giants”. This film is expected to air in middle 2018.
