Dave Pepler
Dr Dave Pepler received an Honorary Doctorate in Zoology from the University of the Free State during the April Graduation Ceremonies 2023.

“Growing up in the tiny town of Robertson – a strange little Klein Karoo village – I had a grandfather on my mother’s side who took me by the hand every week, put me in a wheelbarrow, and pushed me out of town because we did not have cars. He systematically, and with infinite patience, taught me his view of nature, which has never left me.”

Dr Dave Pepler recalls these memories with his grandfather, stating that this time with Oupa Boy le Roux, whom he describes as illiterate but with a vast reading knowledge, is one of the biggest reasons for his passion and love for nature today.

“He sensitised me to a specific optic of looking at nature. The excitement that he instilled in me has stayed with me to this day. I will never forget the days in the veld with my grandfather, teaching me the ways of the veld."

On 21 April 2023, the Faculty of Natural and Agricultural Sciences at the University of the Free (UFS) conferred an Honorary Doctorate in Zoology upon Dr Pepler – nature enthusiast and conservation philosopher – for his significant contribution to society as ecologist, naturalist, and environmentalist.

I am a Kovsie

In his acceptance speech, Dr Pepler said, “I accept this honour with deep gratitude and a hell of a lot of pride.” Paraphrasing President John F Kennedy in Berlin in 1963, he said, “Jetz, bin ich ein Kovsie.”

He holds an MPhil in Zoology from the University of Cambridge and was a Research Associate in the DST Centre of Excellence for Invasion Biology in Stellenbosch until 2022. 

Dr Pepler has published many peer-reviewed articles and contributed chapters in academic literature. Some of his recent work has been published in Violence against Nature and the Morality of Ecology. “The latter sounds like a contradiction, but it is the only way we could protect nature – by giving nature human status. We can be ethical but never moral it if is not a legal person. By granting systems, landscapes, rivers, and mountains human rights, we can start defending their rights,” he said.

He has also been consulted on many projects throughout Africa, sharing his knowledge on biodiversity and conservation management, among others. As a specialist tour guide, he has conducted expeditions to Iceland, Borneo, India, Ethiopia, Egypt, Morocco, Uganda, Rwanda, and Madagascar. He was particularly captivated by the beauty of nothingness that he found in Iceland and Namibia.

My interest in ecology is purely incidental. I am infinitely more interested in architecture, philosophy, aircraft, but my bread and butter are ecology. – Dr Dave Pepler

During his lifetime he received numerous awards and high honours, including the Molteno Medal from the Cape Tercentenary Foundation for his outstanding contribution to conservation, the Stevenson Hamilton Award from the Zoological Society of Southern Africa, and the South African Habitat Council Life Achievement award.

For many South Africans, Dr Pepler is a well-known face as presenter of the environmental documentary programme, Groen (and for the young ones, Groentjie), giving a close and personal experience of nature. Besides his 81 000 followers on Facebook, he also made numerous contributions to the Radio Sonder Grense radio programme, ‘Hoe verklaar jy dit?

Much to be proud of

Receiving his honorary degree in person, Dr Pepler had the opportunity to visit the Bloemfontein Campus of the university. After meeting with academics in several of the departments in the Faculty of Natural and Agricultural Sciences, he expressed his admiration for the different centres of excellence at the university, stating, "You have much to be proud of." 

Later in the day, he inspired graduates at the faculty’s Academic Awards Ceremony, urging them to find their own voice, especially in a world where artificial intelligence is now finding its foothold in society. 

According to him, the glory of scientific writing lies in an individual voice – the writer’s voice ringing through his work uniquely. He encouraged the graduates to go out and develop their own voice.

Dr Pepler also stressed the importance of reading, and – on a lighter note – quoted an English dictionary writer from 1962, who said, “The children of today is not reading anymore.” 

“Read, not binge-watch series on Netflix,” he appealed to the audience.
 
“Connections, connections, connections. The more you read, the more connections you can make. This not only holds true for science, but also the arts,” he pointed out.

Dr Pepler impelled the group of alumni to become anything they wish to achieve. “Go out and do it,” he concluded.

UFS student makes breakthrough in the application of nanorobots
2005-04-21

A student from the University of the Free State (UFS) has made a ground-breaking discovery in the field of microbiology by uncovering a series of new compounds that may in future be used to lubricate man-made nanorobots.

Mr Olihile Sebolai, a full-time student at the UFS’s Department of Microbial- Biochemical and Food Biotechnology, made this discovery while working on his M Sc-study on yeast.

With this discovery Mr Sebolai will also be awarded six prestigious prizes during this week’s autumn graduation ceremony at the UFS.  This university has recognised this exceptional achievement as a build-up to the celebration of national Science and Technology week next month.     

Mr Sebolai’s dissertation on the yeast genus Saccharomycopsis Schionning has been published in an accredited international journal of repute. 

“Words cannot describe how excited I am. I never expected to receive such recognition for my studies.  I am humbled by all of this,” said Mr Sebolai.

The Lipid Biotechnology Group at the UFS recently discovered that some yeasts produce their own water-propelled capsules in which they are transported.  These capsules have different shapes and resemble among others miniature flying saucers, hats with razor sharp brims etc.  “In order to function properly, parts of the capsules are oiled with prehistoric lubricants – lubricants that are produced by yeasts and that probably existed for many millions of years as yeasts developed,” said Mr Sebolai.  

According to Mr Sebolai these capsules are so small that approximately 300 can be fitted into the full-stop at the end of a sentence and are therefore invisible to the naked eye.

“With my studies I discovered many new compounds that resemble these prehistoric lubricants.  These lubricants may in future be used to lubricate man-made nanorobots and are similar in size compared to yeast capsules,” said Mr Sebolai.  The nanorobots are used to perform tasks in places that are invisible to the naked eye and could one day be used, among others, to clean up human arteries.

Mr Sebolai has been interested in the subject of Micro technology since he was at RT Mokgopa High School in Thaba ‘Nchu.  “I was specifically interested in the many possible applications the subject has – in the industry, as well as in medicine,” said Mr Sebolai. 

His next goal is to successfully complete his Ph D-degree.

The prizes that will be awarded to Mr Sebolai this week include:

Best Magister student at the UFS (Senate medal and prize);

Best Magister student in the Faculty of Natural and Agricultural Science and Dean’s medal at the same faculty;

The Andries Brink – Sasol-prize for the best M Sc dissertation in Microbiology;

The JP van der Walt prize for best M Sc dissertation in yeast science;

The Chris Small prize for an outstanding Master’s dissertation; and

Honorary colours awarded by the UFS Student Representative Council
