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.

Breakfast in aid of hungry students
2011-06-01

Our university again proved that it cares for the welbeing of its students when a sum of money was presented to the No Student Hungry Project during a breakfast function.

The Centre for Health and Wellness at the UFS organised the event, not only to introduce the scheme to staff and individuals and thank those concerned for their contributions, but also to present the project organisers with a donation of R50 000. Mrs Grace Jansen, wife of Prof. Jonathan Jansen, Vice-Chancellor and Rector and Dr Carin Buys, wife of Mr Rudi Buys, Student Dean, started the project this year after a study found that 20% of students at the UFS have to study on an empty stomach and that this often leads to students leaving the UFS prematurely.

Ms Tanja Malherbe, mistress of ceremonies, said that the project is blessed because it developed from the founder members’ love for the students. The project currently provides 6 000 deserving students with a meal per day.

Prof. Jansen said that although the university encourage academic success, the UFS is also ready to show its mettle on a humanitarian level. “We don’t want students to only study together, but also to eat together.” He added that food can promote a feeling of fellowship, gives comfort and is also a symbol for caring. “It is bad to be hungry, no matter what the colour of your skin. Especially when other people have food and you don’t.”He concluded by saying that we are blessed by giving to other people, and by giving, we also receive.

Ms Tarryn Nell, also from the centre, supported him by comparing caring to candlelight. “It drives the darkness away, involves compassion and gives direction. When two people can get things to change, the rest will follow.” She encouraged the audience to share their warmth, time, knowledge and resources with other people.

During the event, a picture summary also referred to two recent projects the centre hosted. The first was a free medical screening test for staff members and the second a temporary remembrance rose garden, representing the five main causes of deaths in the country. These causes are HIV, ischemic heart disease, stroke, tuberculosis and interpersonal violence.

The proceeds from Prof. Jansen’s book “We need to talk,” will be donated to the project. Persons wishing to make a contribution, can make a payment to the following account: ABSA 157085 0071, reference number 146 674 604, account number 0198, branch code 632 005. Deposit slips can be sent to pelserr@ufs.ac.za.
