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.

Council votes on appointment of senior staff
2004-11-18

The Council of the University of the Free State (UFS) today voted on the filling of three senior vacancies, including one post at Dean level and two at the level of Vice-Dean.

The Council voted as follows:

Dr Natie Luyt will be offered the post of Dean: Student Affairs Prof Engela Pretorius will be offered the post of Vice-Dean: Faculty of Humanities Dr Choice Makhetha will be offered the post of Vice-Dean: Student Affairs

“There are special challenges for the UFS in the short and medium term regarding transformation of our residences, and a certain combination of management qualities and skills is desirable. As a result of the diversity of the UFS’s student community it is therefore important to us to follow a team approach to deal with the challenges. With the combination of Drs Luyt and Makhetha, I believe we will be able to manage student affairs effectively and skillfully,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

“It is wonderful that we are able to celebrate the outcome of this process that has brought forward such excellent candidates who reflect our country’s diversity. It shows that we can achieve the goals of quality and diversity at the same time,” says Prof Fourie.

Prof Pretorius obtained all her qualifications (BA, BA (Hons) (cum laude), MA (cum laude) and D Phil) from the UFS, except for the Certificate in Gender Policy Management (cum laude) which she obtained in 2000 from WITS. She joined the Department of Sociology at UFS in 1980 and has headed the Department since 2001. She acted as Vice-Dean: Faculty of Humanities since July 2004. She has some thirty publications to her credit, published both nationally and internationally and has delivered 20 national and international papers. She is a member of the South African Sociological Association and is a member of the Council of the association and of the Editorial Board of Society in Transition, the society’s journal. She is also a member of the South African Academy for Science and Art and the Federation of African Women Educationalists in South Africa (FAWESA). Project involvement includes the Australian Women’s Executive Development Programme and the project Executive Development of Senior Women in South African Higher Education Institutions. She is also an NRF panelist.

Dr Luyt obtained his qualifications (BA, BA (Hons) (cum laude), MA (cum laude) and D Phil) at the UFS and started his career at the same institution in 1980 as lecturer in Political Science. He was promoted to senior lecturer in 1983 and appointed as Director: Student Affairs in 1997. He has been acting as Dean: Student Affairs since 2003. Dr Luyt completed several work-related training courses, among others a course in ethnic and multiculturality at the Swiss Institute for Federalism and a course in conflict management at the South Tyrolean Economic and Social Institute.

Dr Makheta also obtained all her qualifications (BA, BA (Hons), MA in Political Science and Ph D in Political Science) at the UFS and started working as a student assistant in Political Science at the same institution in 1999. She was promoted to junior assistant in 2000, coordinator and facilitator of Political Science in 2001, assistant/acting Director: Student Affairs in 2001 and acting Director: Student Affairs in 2003. Dr Makhetha is currently a Senior Political Analyst at the Department of Foreign Affairs.

The UFS Council also approved the promotion of nine professors to the rank of senior professor. They are Proff Louise Cilliers (Department English and Classical Languages), Dap Louw (Department of Psychology), Philip Nel (Department Afro-Asiatic Studies, Sign Language and Language Practice), Dirk van den Berg (Department of History of Art and Visual Culture Studies) Dingie van Rensburg (Director: Centre for Health Systems Research and Develoment), Andries Raath (Department of Constitutional Law and Philosophy of Law), James du Preez (Department of Microbial, Biochemical and Food Biotechnology), Johan Grobbelaar (Department of Plant Sciences) and Louis Scott (Department of Plant Sciences).

This is the first group ever of senior professors at the UFS. The post level was created to provide better career and earnings opportunities for high quality academics and to increase the attractiveness of an academic career to young people.
