It is an important and exciting time to be doing research in conservation genetics. This is according to Prof Gordon Luikart, Professor of Conservation Ecology and Genetics at the Flathead Lake Bio Station at the University of Montana in the United States. 

Prof Luikart, whose primary research focus is the application of genetics to the conservation of natural and managed populations, recently delivered a lecture, The Expanding Role of Genetics/omics in Wildlife Research and Conservation, on the Bloemfontein Campus of the University of the Free State (UFS). The lecture, hosted by the Department of Genetics, was attended by a group of students and lecturers in conservation and a number of related fields. 

He is one of the leading scientists in the field of conservation genetics, including integration of genomics in conservation projects. He is also co-author of the textbook Conservation and the Genomics of populations – the current prescribed textbook for GENE3744.

Species threatened with extinction

In 2008, the International Union for Conservation of Nature (IUCN) stated that approximately 10-20% of all vertebrate and plant species are threatened with extinction over the next few decades. In 1984, American biologist Edward O Wilson also said that it will take millions of years to correct the ongoing loss of genetics and species diversity caused by the destruction of natural habitats. “This is the folly our descendants are least likely to forgive us.”

Prof Luikart is of the opinion that genetics has enormous potential to help manage wildlife and prevent extirpation. “My research works to realise this potential and help wildlife managers conserve populations and ecosystems,” he says. 

Conservation managers and biologists have understood the risks of inbreeding for more than 100 years. In his lecture, one of the aspects of genetic conservation he focused on, was the negative effects of inbreeding and how this can be reversed using genetic rescue. 

With the genetic rescue study, they found that the gene flow into recently isolated populations can increase individual fitness and population growth. He proposed that conservation managers should consider genetic principles and rescue as practical and important tools. 

Prof Luikart also provided a list of information that can be retrieved from molecular genetic data to help conservation managers. This includes intel on census and effective population size, gene flow and dispersal, local adaptation and selection, forensics, genetic identification and law enforcement, and disease ecology and transmission. 

Non-invasive genetic monitoring

In terms of detecting gene flow, he focused on a study about non-invasive genetic monitoring that was conducted in the Yellowstone Park. Prof Luikart and a group of students collected the shed hair and faeces of the grizzly bear, obtained from trees and hair traps, which were used as a source of DNA. 

They established, for instance, that inbreeding depression is more common and stronger than previously thought in natural populations. Genetic monitoring, using non-invasive methods as described, has been found to be an effective tool that conservation managers should consider for detecting inbreeding and loss of genome-wide variation.

His research on the bighorn sheep, the alpine ibex, and the black bear informed most of the findings he discussed during his lecture.

With the recent procurement of SAB by Anheuser-Busch InBev SA/NV (AB InBev), a Belgian transnational beverage and brewing company, the 500L educational brewery located at the SAB Cyril Ramaphosa World of Learning, became available for donation. After an initial shortlisting of three universities, the SAB World of Learning Brewery was awarded to the University of the Free State (UFS) to be managed by Kovsie Brewing.

Prof Corli Witthuhn, Vice-Rector: Research at the UFS, approved the application for a micro-manufacturing liquor licence right in the middle of campus, which effectively put the UFS bid in a class of its own. It is part of her vision that entrepreneurial activities must be visible on campus”

Sixteen universities were approached to obtain the brewery for their respective campuses.

Kovsie Brewing is an initiative started by postgraduate students at the UFS Department of Microbial, Biochemical and Food Biotechnology in 2012. The main objective of this initiative was to expose BSc students to brewing as a practical application of the scientific fields presented at the department.

Label mock-ups made by
Dr Jan-G Vermeulen from
Kovsie Brewery entered into
the yearly  SAB Intervarsity
Brewing Competition. Kovsie
Brewing has won the best label
competition in 2013, 2014 and 2015
and was placed in the top three in
2016 and 2017.


First brewing and fermentation school
Dr Errol Cason, project leader at Kovsie Brewery, said: “Over the past five years the small-scale experimental brewery has steadily grown to the point where we obtained institutional support to establish the first Brewing and Fermentation School at the university.

Dr Cason explains that the primary role of Kovsie Brewing is to establish an accredited fermentation-based curriculum at the UFS to educate undergraduate and postgraduate students in the scientific process involved in the production of beer. “In addition, the donation enables Kovsie Brewing to provide practical job-related training and skills development on industrial grade equipment,” he said.

Emphasis on entrepreneurship
The secondary role is for Kovsie Brewing to function as a multi-disciplinary platform to stimulate the interaction between students from various fields of study. Currently Kovsie Brewing has well-established cooperative projects with both Marketing and Entrepreneurship programmes.

“In the future, Kovsie Brewing will expand on these multi-disciplinary interactions by incorporating other departments of the UFS with the focus on product development, logistics, as well as the legal aspects concerned with brewing,” Dr Jan-G Vermeulen from the Kovsie Brewery team said.

Corporate social investment representatives from AB InBev recently visited the university. Among others they met Drs Vermeulen and Cason. During their visit they also looked at other university projects, including the Department of Paediatric and Child Health and the Universitas Hospital, the Engineering Sciences Department and the Naval Hill Planetarium.

Khosi Mogotsi from AB InBev said: “It was wonderful to experience the passion with which UFS staff do their work.”
