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.

Kovsies to celebrate excellence at 2014 December Graduation Ceremony
2014-12-02

On Thursday 11 December 2014, the University of the Free State (UFS) will award degrees and qualifications during our Summer Graduation Ceremony at the Bloemfontein Campus.

The graduation will take place during two ceremonies in the Callie Human Centre, where master’s and PhD degrees will be awarded during the first ceremony at 09:30. Diplomas, certificates and undergraduate qualifications will be awarded to students from the School of Open Learning and the Faculty of Health Sciences at 14:30.

Radio personality, Redi Thlabi, and cardiothoracic surgeon, Dr Susan Vosloo, will address the graduates.

Apart from her radio show on 702 and CapeTalk, Thlabi has also hosted local television news shows and anchored for international broadcasters like SKY and the BBC. In addition, she has presented two of her own TV shows: ‘Redi’ on Mzansi Magic and ‘South to North’ on Al-Jazeera.

Her first book, Endings and Beginnings (Jacana) received popular acclaim and is currently being turned into a screenplay for a movie.

Dr Susan Vosloo, a Kovsie alumnus, graduated in 1980. She completed her internship in Pretoria and spent the following year in Critical Care Medicine at Universitas Hospital, Bloemfontein, before starting her surgical training in Johannesburg.

She is currently in independent private practice at the Netcare Christiaan Barnard Memorial Hospital in Cape Town, having also worked from 1998 – 2012 at the Vincent Pallotti Hospital in the same city.

Dr Vosloo maintains close ties with our university and has quite a number of addition roles to that of surgeon:

• member of the Council of the UFS;
• UFS Council Representative in the Senate;
• member of the Standing Advisory Committee of the School of Medicine, UFS;
• member of the Provincial Department of Health;
• Africa representative for the Pediatric Cardiac Intensive Care Society; and
• founding member of the World Society for Pediatric and Congenital Heart Surgery.

Prof Boelie Wessels will also be awarded his 10th academic degree from the UFS since 1974. Adding his Honorary Doctorate degree to the list, it will make this his 11th degree. Prof Wessels is 84 years old and has 18-plus academic qualifications from various institutions – a phenomenal achievement.

Furthermore, Moses Lubinga and his wife, Stellah, will be the first married couple to be awarded their PhDs at the same graduation ceremony at the UFS. Mr Lubinga will receive his Doctorate in Agricultural Economics, while Mrs Lubinga’s PhD is in the field of Economic and Management Sciences.
