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.

New head for Student Academic Services
2009-03-05

The University of the Free State (UFS) has appointed Mr Frank Madimetja Nkoana, pictured, as the new Director of Student Academic Services (SAS).

Mr Nkoana has a wealth of experience having worked for 24 years in the field of academic administration, 14 of which have been in leadership and senior management positions, at various institutions of higher learning.

In this post he will supervise applications, admissions, financial aid and registrations through to graduations.

The Director: Student Academic Services has a pivotal role to play in developing and supporting the University’s educational agenda.

“I consider my appointment to the Division as the correct one at the right time and a blessing to the UFS in view of my experience and training in the field of academic administration,” he said.

He believes it is only through effective and efficient academic support services that the institution can achieve excellence in its academic endeavour in tandem with its vision of being “an excellent, equitable and innovative University”.

“I must see to it that SAS, as both a sector and a process, is sufficiently and appropriately supported and maintained through an effective administrative structure that is manned by skilled and well-trained personnel, adding thereto continuous development and job enhancement – thus creating a conducive environment for efficiency and effective service delivery to students, staff and the wider community,” he said.

However, he is also mindful of the challenges facing him and the Division. He considers as his main challenge, among others, the creation of a Division that is functionally able and has as its goal the achievement and provision of effective academic administrative support to the core university business.

“Our operations should be in line with new developments in academic administrative systems to enable the UFS to achieve academic excellence and global competitiveness,” said Mr Nkoana.

“We must be able to establish and strengthen a high level of ethos of service delivery and develop good human relations between the staff and the students.”
