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 Centenary celebrations come to an end
2005-02-03

OFFICIAL OPENING

The official opening of the UFS will take place on Friday 04 February 2005 at 09:00 in the Reitz Hall (Centenary Complex). Please note that this is a test and lecture free day. The Rector and Vice-Chancellor, Prof. Frederick Fourie will be the keynote speaker. Refreshments will be served at the Centenary Complex after the opening ceremony.

The historic Centenary photograph will be taken at 11:00 on the eastern side of the Red Square (CR Swart parking area). All staff members and students are invited to be part of this massive photograph.

Important

• There will be no parking allowed on the CR Swart parking area until 12:00 on Friday 04 February 2005, as a result of the photo session.

• All academic staff members are requested to wear academic dress on the day, seeing as staff members will depict the Centenary emblem on the photograph. Academic gowns may be collected from the Gown Store on Wednesday 02 - Thursday 03 February 2005 between 08:00 and 16:00. Gowns must be returned to the Gown Store after the photograph has been taken.

SERVICE OF DEVOTION

A special service of devotion will take place on Sunday 06 February 2005 at 18:00 for 18:30 in front of the Main Building on the Red Square. This is a special gathering of students, hosted by all the interdenominational groups on the UFS campus. The evening will be a celebration of praise, thanks and worship, followed by a message from Dr Wollie Grobler. The evening will conclude with song and fireworks.

Staff members and students are welcome to bring their friends and families to this special event.

Important

• Even though there will be chairs in front of the Main Building, staff members and students are requested to bring extra pillows and blankets to sit on.

• No persons or vehicles will be allowed on the eastern side of the Red Square or on the CR Swart parking area, due to the security requirements of the fireworks show.

• All members of the choir are invited to be part of the mass choir. Lyrics will be provided.

• All persons who attend this event are requested to bring a candle for the purpose of the mass choir.

• Special transportation arrangements will be made for all service workers to enable them to attend the service. If there is someone in your faculty, department or division who would like to make use of this service, please send an e-mail to Elize Rall (ralle.stg@mail.uovs.ac.za) no later than Tuesday 01 February 2005.

OTHER ACTIVITIES

• A reunion for all former SRC members of the UFS will take place on the campus, from 04 February to 06 February 2005. An interesting programme is being planned. For more information, please contact Nicolaas du Plessis on 084 955 0875.

• The annual Rag Procession will take place on Saturday 05 February 2005. For more information, contact the Rag Office at X 2718.
