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 acts fast in expelling students for serious misconduct
2014-02-22

On the evening of Monday 17 February 2014, Muzi Gwebu, a fifth-year student in BCom Economics, while walking on the Bloemfontein Campus of the UFS, was side-swiped by a vehicle driving recklessly through campus. He followed the vehicle where it stopped at one of the residences and approached the two occupants. A confrontation started and he was assaulted by one of the occupants of the vehicle.

Gwebu sustained minor injuries and was immediately assisted by the university’s residence life division. He lodged a complaint of assault at the South African Police Service (SAPS).

The senior leadership of the UFS is shocked and outraged at this blatant act of violence against one of its students. The Vice-Chancellor and Rector, Prof Jonathan Jansen, says: “We regard this incident in a very serious light and we worked closely with the SAPS throughout the night to identify and locate the perpetrators who were driving with false number plates.”

With the assistance of the student leadership in one of the residences, the owner of the vehicle and his companion were traced this morning.

The two students were immediately handed to SAPS by the university’s Protection Services and were arrested on charges of attempted murder, assault and driving with false number plates.

In addition to the criminal investigation by the SAPS, the university is also conducting an urgent and formal investigation into the incident.

The university has offered Gwebu full counselling and support until he is fully recovered.

“It is sad and disappointing that, after so much progress with the social transformation of the UFS, such a horrific incident could have occurred. It is pleasing, however, that across the board, all our students condemned these vicious acts. The students, if found guilty in the criminal and institutional investigations, will definitely not be allowed to study at the University of the Free State,” he said.

Statement by Dr Willy Nel, Residence Head of Armentum men’s residence

The Residence Head, Residence Committee and all residents of Armentum male residence on the Bloemfontein Campus unequivocally distance themselves from any behaviour which does not breathe the letter and spirit of the University of the Free State's vision of Human Embrace and Academic Excellence. We work tirelessly to upend traditions that are contradicting this vision. Therefore we add our voice to those who condemn the incident in which ex-residents allegedly assaulted a pedestrian who is also a student of our institution. We express our support to and confidence in the university's and other processes to find justice in this matter.

Dr Willy Nel
Residence Head: Armentum
