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.

Kovsie Biggest Braai a huge success

Even though Braai Day is celebrated nationally in September, students at the University of the Free State (UFS) had their own braai day. The Kovsie Biggest Braai was the biggest student community event of the year.

Takudzwa Nyamunda of the International Student Council said the idea for the braai came from the International Student Association as a social cohesion event for international students. “When the idea was presented to my office we realised the potential for such an initiative to be not just for students but for the whole Kovsie community.”  

They realised there were not a lot of social cohesion events on campus where students and staff could just take a day to relax and embrace the feeling of being a Kovsie. He said he believed the braai could provide the right platform. The main objective of this project was to make it an institutional event with aspects of fundraising for the future. 

Colleges made KBB a success 
An estimated 3500 people attended the festivities on Red Square on 12 August. “We used the college format for the braai and it was set in the form of a challenge between the five colleges, but one of the colleges pulled out,” Takudzwa said. The colleges that did participate made a big contribution towards the success of the event and did all the braaing and selling. 

Creating new Kovsie traditions 
The idea behind the pilot project is that it becomes an annual event which in turn will form part of a new Kovsies tradition. “It received endorsement from top management therefore I believe it will form part of the Kovsie calendar for years to come,” Takudzwa said.
