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.

Statement: Visit of the Portfolio Committee on Education to the UFS
2005-02-25

The chair of the Portfolio Committee on Education (PCE) Prof Shepherd Mayatula has commended the management of the University of the Free State (UFS) for its positive approach to the incorporation of the Vista and Qwaqwa campuses.

According to a statement issued by the university’s communication section, Prof Mayatula said that while there were outstanding issues to address, a platform had been created through the visit of the portfolio committee for the UFS to find solutions.

Speaking at the end of a visit to the Bloemfontein campus of the UFS, Prof Mayatula said: “You know the issues that exist between the three campuses and you know the solutions. You don’t need recommendations from the Committee.”

Earlier today the PCE held a three-way meeting between the PCE, the management of the UFS and the Vista Task Team, representing staff and students at the Bloemfontein campus of the former Vista University .
 

The Bloemfontein campus of the former Vista University was incorporated into the UFS in January 2004.

The multi-party delegation from the PCE was led by its chairperson, Prof S Mayatula, while the delegation from the UFS was led by the Rector and Vice-Chancellor, Prof Frederick Fourie, while the Vista Task Team was lead by Mr Paseka Mokoena.

Following a presentation by the Vista Task Team and a presentation by the UFS management, other committee members also commended the UFS for the spirit in which outstanding issues were being handled.

It was indicated by portfolio committee members that other universities have far more serious problems than the UFS, and that some of these universities have also been visited by the PCE. The UFS appears to be on the road to be an important pilot case for incorporations and mergers.

The issues that were discussed during today’s meeting included the following:

  • outstanding issues in the process of incorporating the Bloemfontein campus of the former Vista University into the UFS, including:
  • staff issues and conditions of service
  • issues of student aid and pipeline students
  • governance of the UFS
  • the long term utilisation of Vista as a site

The Rector and Vice-chancellor of the UFS, Prof Fourie, expressed his appreciation for the role played by the Portfolio Committee on Education in bringing about a common understanding of the transformation issues facing the UFS.

Prof Fourie said the Portfolio Committee’s visit was a useful intervention to bring about a sense of urgency in resolving matters affecting the Vista campus as well as the Qwaqwa campus.
