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 in partnership with USA ’s Council on Economic Education 

A group of 50 teachers in Economics, learning facilitators and lecturers from eight countries attended a ‘train the trainers’ workshop this past week in Bloemfontein.  The workshop forms part of the outreach programme of the National Council on Economic Education (NCEE) in the United States of America’s (USA) effort to improve the quality of the training in Economics of teachers and lecturers across the world. 

The UFS and the Free State Department of Education are the NCEE’s first partners in Africa.  “The initiative started in the Free State because of the connection that existed between the UFS and the NCEE,” said Prof Klopper Oosthuizen, from the UFS Department of Agricultural Economics and initiator of the cooperative agreement with the NCEE.

Three faculties at the UFS are involved in the cooperative agreement namely the Faculty of Natural and Agricultural Sciences, the Faculty of the Humanities and the Faculty of Economic and Management Sciences.

A group of 84 teachers and learning facilitators in the Free State attended the ‘train the teacher’ workshop at the UFS in December 2005 in an effort to improve the quality of Economics classes at schools in the Free State.  The last national workshop will take place in June 2006 in Bloemfontein.  During this workshop a group of 40 teachers and learning facilitators in the Free State will be trained by the NCEE.    

“Because of the success with the programme in the Free State Dr Patty Elder, Vice-President of the NCEE’s national programme, announced during last week’s workshop that the initiative will now be extended to the other provinces in the country,” said Prof Oosthuizen.  According to Prof Oosthuizen discussions around a strategy to get the other provinces on board of the programme also took place between Dr Elder and Prof Herman van Schalkwyk, Dean of the UFS Faculty of Natural and Agricultural Sciences.  Prof van Schalkwyk will take the lead in this regard.  

“The presence of Dr Elder and the executive directors of similar education networks in the Ukraine and Indonesia is an indication of the NCEE’s seriousness with the programme in Africa,” said Prof Oosthuizen.

Prof Oosthuizen explained that South Africa is competing to obtain funds from the NCEE to have a total South African representation in the workshops in the following one-year training period. 

South Africa has a good chance of establishing the network quickly because of the presentation of the last national workshop in Bloemfontein in June 2006.  “We are going to try to have as much South African representation as possible at this workshop,” said Prof Oosthuizen.

Concurrent with the workshop in June 2006, a programme will be developed that will be attended by at least five other provincial education departments and representatives of five other universities.  These representatives will then be able to observe on a first-hand basis how this action learning takes place and how the participating countries plan to establish and expand their networks,” said Prof Oosthuizen.

“The NCEE has been working together with international partners since 1992 to strengthen their Economics teaching systems.  They have already succeeded in increasing literacy in Economics of schools in the USA and more than 20 East Block countries.  More than 1,5 million learners in the East Block countries have already been served by this initiative,” said Prof Oosthuizen.

According to Prof Oosthuizen the focus of the NCEE has since 2004 moved away from the East Block countries to Africa, Asia, Latin America and the Middle East.  The representatives that attended last week’s workshop were from South Africa, Egypt, Jordan, Palestine, Indonesia, Mexico, Paraguay and Uruguay.  Countries such as Egypt, who was also present at last week’s workshop, are eager to start a similar network.
