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.

As a world-class tertiary institution, the University of the Free State (UFS) boasts with three new buildings on its Bloemfontein and Qwaqwa Campuses since 2015. All of these buildings are extensions to current buildings, supporting the university’s vision of excellence in academic achievement.

Extensions and additions to the value of R23 million were made to the existing Biotechnology Building. The funding was provided by the Department of Higher Education and Training. The additions were made to the southwestern corner of the existing building. Further developments to the building includes: six new offices, a lecture hall for 70 students, and laboratories accommodating 56 postgraduate students.

Prof Martie Smit, Academic Head of this department, says: “This new and refurbished facility enables us to give our best. As academics, we are committed to do our part in delivering high-quality education on both undergraduate and postgraduate levels to students envisaging a future in biotechnology.”

Dr Lis Lange, Vice-Rector: Academic, is proud of the heights the department has reached to date. “The Department of Physics is undoubtedly one of the jewels in the crown of our university, and we are very proud of its developments. Universities are built on legacies, and they are also about change, which is what this department has been demonstrating.”
The new Physics and Geography Complex on the Qwaqwa Campus is connected to the existing Chemistry Building. The building is the first of its kind on the campus and boasts an auditorium with 360 seats and a Geography Information System laboratory with 100 work stations.
