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.

Pre-story: Inauguration of Prof F Petersen as 14th Rector of the UFS
2017-05-08

“At the UFS, we want to produce graduates for the world, and we need to ensure that we use our knowledge to uplift society”
— Prof Francis Petersen, 14th Rector of the University of the Free State (UFS)

This week marks the first stage of the official welcoming and inauguration of Prof Francis Petersen as the 14th Rector of the UFS, who assumed his duties on 1 April 2017. 

Proceedings will commence on our Qwaqwa Campus, with a function at which the community is to welcome the incoming Vice-Chancellor and Rector. The event on Thursday 11 May 2017 is expected to attract a wide spectrum of community leaders in the area. Speakers to welcome Prof Petersen will include representatives from the two trade unions, National Health Education and Allied Workers Union (Nehawu) and UVPERSU, as well as representatives from the Student Representative Council (SRC), Thabo Mofutsanyana Education District, and the House of Traditional Leaders.

On Thursday 18 May 2017, the South Campus in Bloemfontein hosts a welcoming ceremony for the new Vice-Chancellor and Rector, including a number of vocal performances and messages from various campus stakeholders. On Thursday afternoon, the Institute for Reconciliation and Social Justice (IRSJ) will also facilitate a panel discussion in the Albert Wessels Auditorium (AWO) on the Bloemfontein Campus.

The inauguration proceedings culminate in an event in the Callie Human Centre on Friday 19 May 2017 at the Bloemfontein Campus, with number of performances by musicians and school choirs to further embellish the function. Key stakeholders will also have the opportunity to convey their messages of welcome to Prof Petersen. The formal inauguration ceremony will take place on the Bloemfontein Campus on the same day.

As the above events take place, this article will be updated with the most recent photographs and other information.
