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 closes pedestrian entrances to improve safety on campus
2010-08-05

The University of the Free State (UFS) will remove pedestrian gates on its Main Campus in an extra effort to improve safety on this campus.

It was decided to implement this plan because the campus covers a huge area and people who are not part of the campus community hang around on the campus, sometimes causing damages. This idea is also strongly supported by students, in particular with regard to the removal of the pedestrian thoroughfares close to the hostels.

The following pedestrian gates will not be removed:

- The pedestrian thoroughfares on both sides of the DF Malherbe Gate (next to the Faculty of Health Sciences). Both the main gate and the pedestrian thoroughfares at the DF Malherbe Gate remain open 24 hours a day.
- The pedestrian thoroughfares at the Badenhorst Street Gate (close to Roosmaryn Residence). The Badenhorst Gate is not open 24 hours a day, but the pedestrian thoroughfare will remain open 24 hours a day.

The following pedestrian thoroughfares will be removed with effect from 1 September 2010:

- The pedestrian thoroughfare to the east of Pellies Park
- The pedestrian thoroughfare to the west of Pellies Park (directly behind JMB Hertzog Residence)
- The turnstile between the Kovsie Church and the Wynand Mouton Gate
- The pedestrian thoroughfare behind the tennis courts
- The pedestrian thoroughfares behind the rugby fields

A request was also directed at the Kovsie Church to close down the pedestrian thoroughfare between the Kovsie Church and the UFS. This gate will then be opened during church activities.

From 1 September 2010, the personnel of Security Services will regularly patrol the fences. Trespassers that flatten the fencing to enter the campus will be prosecuted.

Students, personnel and visitors are encouraged to make use of the main entrance gates of the UFS. These include the Main Gate (in Nelson Mandela Drive), the Wynand Mouton Gate (in DF Malherbe Drive), the DF Malherbe Gate (in Wynand Mouton Drive), the Badenhorst Street Gate (close to Roosmaryn Residence) and the Furstenburg Gate (in Furstenburg Road).
