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.

UFS establishes Centre for Education Development
2007-09-26

At its meeting on 14 September 2007 the Council of the University of the Free State (UFS) took a number of key decisions on matters recommended by the Executive Management of the university for its consideration or approval.
 
The Council gave the green light for the merger of the Section Upgrading of Education (School of Education) and Research Institute for Education Planning (RIEP) to create a single unit for education development. The qualifications and courses currently offered by these two units will henceforth be offered by the newly formed unit. The new unit will be known as the Centre for Education Development.
 
Under this new dispensation, amongst others, the functions of the unit will be extended to include other in-service training of teachers and empowering courses and qualifications as well. Some of the existing RIEP courses will be converted into credit-bearing short courses in more learning areas than are presently available, and that the focus will also be on offering short courses as the need may arise. Research will become a prominent function of this new unit.
 
The Council has also approved the reinstatement of the Department of Genetics as a stand-alone department. Currently Genetics is a sub-discipline of Plant Sciences. Its reinstatement as an independent department will have several advantages for the Faculty of Natural and Agricultural Sciences, as well as the university, namely:
 
- with its own identity, Genetics as a subject will attract more students, through which the UFS will be able to get more subsidies.
- postgraduate students who leave the university for others will have an incentive to stay.
- researchers in Animal Genetics and Behavioural Genetics will be able to fulfil their full role.
- service delivery to the industry will result in the generation of third-stream income.
 
The Council also extended the terms of office of the Dean of the Faculty of Law, Prof Johan Henning, and that of the Director of Finance, Mr Chris Liebenberg, for a further five years each.
 
The Council further appointed Dr Elias Nyefolo Malete as the Campus Principal of the UFS Qwaqwa Campus for a term of three years. Dr Malete has been acting in that position prior to his appointment.
 
Other matters involved the condonation of the Council’s 1995 resolution to sell the Hertzog House in Goddard Street in Bloemfontein, and the approval of the sale of another house in Biddulph Street in Harrismith.
