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.

Campus-wide poll to determine preferences among current staff and students for language models
2015-10-28

New dates: Campus-wide poll to determine preferences among current staff and students for language models – 29 October to 4 November 2015


Due to the past week’s national #Feesmustfall student protest action, the language poll has been moved to 29 October 2015-4 November 2015 on all three campuses.

The poll will take place at the following venues from 29 October to 4 November 2015, 08:00-16:30, including the weekend:

Bloemfontein Campus:

Kestell Residence Gazellie
(Map from Main Gate to Kestell Residence: https://www.google.com/maps/d/edit?mid=zpxto53qbJos.kvfli1pCFvWQ&usp=sharing

Fish Tank, SRC Building, Thakaneng Bridge

Online option available:

Go to http://www.ufs.ac.za/language to participate. This URL will be active as from Thursday 29 October at 08:00. Staff to log in with their username and password and students to use their UFS credentials (your username is your student number and your password is the one you use to log in on Blackboard).

Please note that the campus-wide poll is NOT a formal voting process or referendum and will form only one part of many deciding factors that will be referred to the UFS Council on 4 December 2015 for their deliberations regarding the future of the language policy at the UFS. The poll, conducted by the Independent Electoral Commission (IEC), will be indicative of the preferences of staff and students for possible language model options, with specific focus on language of instruction.  

To take part in the polling at the allocated venues, a valid staff or student card must be produced. Polling will take place on the basis of one poll per current staff member/student.

We look forward to your participation in the poll and hereby thank the entire university community for their ongoing interest and responsible engagement with the review process.
