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.

To celebrate Oliver Reginald Tambo’s centennial year, the Oliver and Adelaide Tambo Foundation, in partnership with the Rector and Vice-Chancellor of the University of the Free State (UFS), Prof Francis Petersen, and Absa Bank, hosted an interactive dialogue session, titled “Educating Africa’s Future” on 26 September 2017 on the Bloemfontein Campus.

Students encouraged to take charge of their future
The event opened up dialogue on some of the current burning issues that affect students in South Africa, societal challenges such as poverty and crime, and how leaders such as Tambo envisaged a free Africa. Prof Petersen highlighted the role that universities played in developing society, in creating leaders and crafting the path to transformation. Other speakers included Pali Lehohla, outgoing Statistician-General, Linda Vilakazi, CEO of the Oliver and Adelaide Tambo Foundation, Nombulelo Nxesi, CEO of Education, Training and Development Practices, Sector Education and Training Authority, Prof Peliwe Lolwana, Associate Professor at Wits University’s Centre for Researching Education and Labour, and Sikhululekile Luwaca, former UFS Student Representative Council (SRC) president.

Education may require a new approach
During the panel discussion that was facilitated by Phiwe Mathe, former UFS SRC President and media officer in the Office of the Chief Whip of the Free State Legislature. The audience raised concerns regarding the future of funding for university study, the securing of employment and possibilities, if any, of entrepreneurship. In response to some of the concerns, Pali Lehohla said the realities of family dynamics in South Africa affected the ability of students to be properly profiled and funded, according to family income, and that most importantly, the solutions to Africa’s challenges had to come from within and not without. Students’ questions gravitated towards the question of whether higher education in its current form was still valuable or whether new models of teaching that would foster inclusion and earlier economic independence would be of better value.

The legacy of OR Tambo continues to be honoured
The notion of education as a driver for the liberation of South Africa and the continent as a whole, poverty alleviation and freedom from colonial rule are some of the building blocks of the legacy of Oliver Tambo. 
Linda Vilakazi reiterated that students and student leaders would benefit from seeing the importance of using a broad-based African approach to the issues that plague them and their peers, rather than seeing their challenges outside of the continental context.  Sikhululekile Luwaca said higher education must be more accessible, and in order to drive change, students should use their education to become future employers rather than employees and change the face of the future themselves as was envisioned by other liberation leaders.
