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.

Graduation Livestream

Two honorary doctorates and a Chancellor’s medal will be some of the highlights during the End-of-year Graduation Ceremonies at the University of the Free State (UFS).

The Callie Human Centre on the Bloemfontein Campus will once again welcome graduates, their parents, friends, and relatives for the celebrations on 6 and 7 December 2017. A total number of 1226 qualifications, including diplomas, certificates, and degrees, will be conferred during the two days.

Altogether 40 doctorates and 109 master’s degrees will be awarded. Most doctorates (19) will be awarded in the Faculty of Natural and Agricultural Sciences, while most of the master’s degrees (27) are in the same faculty.

Prof Holloway, Botha, and Isaacs honoured
Prof Paul Holloway (Natural and Agricultural Sciences) and Marius Botha (Law) will receive honorary doctorates during the afternoon ceremony on 7 December 2017, while Joyene Isaacs (Natural and Agricultural Sciences) will be honoured with a Chancellor’s Medal.

Prof Holloway is an internationally acclaimed expert in the science and technology of surfaces, thin films, and nanoparticles, and Botha has played a significant role in financial planning in South Africa. Isaacs is the Head of Department of the Western Cape Department of Agriculture, and her department has been nominated by the South African Institute of Government Auditors as the best government department. 

Young leader, young alumnus, and humanitarian

Likeleli Monyamane, Leah Molatseli, and Dr Imtiaz Sooliman will be the guest speakers at the ceremonies.

Monyamane, a UFS Council member, will address graduates on 6 December 2017 during the morning ceremony. She is one of 15 young leaders selected to represent Lesotho as participants in the Mandela Washington Fellowship in the United States. In 2016, Molatseli, the speaker during the afternoon session on 6 December 2017, launched South Africa’s first legal ecommerce website, Lenoma Legal, and is the university’s most recent Young Alumnus of the Year.

Dr Sooliman, the speaker at both ceremonies on 7 December 2017, is the founder and Director of the Gift of the Givers Foundation. He has received more than 100 national and international awards, citations, commendations, and special recognition for his humanitarian work.

Date: 6 December 2017
Time: 09:00: All qualifications up to Honours degrees in the Faculty of Economic and Management Sciences (including the Business School) and the Faculty of Natural and Agricultural Sciences
14:30: All qualifications up to Honours degrees in the Faculties of Education, Law, the Humanities, and Theology

Date: 7 December 2017

Time: 09:00: All qualifications up to Honours degrees in the Faculty of Health Sciences and Educational qualifications in Open Distance Learning – South Campus
14:30: Master’s and Doctoral degrees in all faculties
