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.

Deadline for written submissions extended to 12:00 on Wednesday 15 November 2017

Deadline for written submissions extended:  Investigation/review into the handling of student protests on the Bloemfontein and Qwaqwa campuses by private security companies during october 2017.

A panel, consisting of Mr Ashraf Mahomed and Ms Nomfundo Walaza, has been appointed by the University of the Free State (UFS) to investigate/review the handling of student protests on the Bloemfontein and Qwaqwa Campuses by private security companies during October 2017. 

Mr Ashraf Mahomed is an attorney and director at Ashraf Mahomed Attorneys in Cape Town. He specialises in constitutional law, administrative law, public law, alternative dispute resolution (including mediation, arbitration, negotiation and facilitation), and land reform law. Mr Mahomed serves as a board member of the Dullah Omar Institute (DOI) for Constitutional Law, Governance and Human Rights at the University of the Western Cape, as well as the Tshisimani Centre for Activist Education. He recently completed his second term as President of the Cape Law Society (CLS).
 
Ms Nomfundo Walaza is a clinical psychologist who has worked in the human rights field for the past two decades. For the past nine years, she has served as the CEO of the Desmond Tutu Peace Centre and also served for 11 years as the Executive Director of the Trauma Centre for Survivors of Violence and Torture in Cape Town. Ms Walaza is currently the Executive Director of PeaceSystems – a civil-society organisation that supports the development of sustainable institutions and systems that prevent, manage, and resolve conflict in African societies.
 
This is an independent panel, which was requested by the Rector and Vice-Chancellor of the UFS on behalf of the UFS Executive, and supported by the President of the Central Student Representative Council on behalf of the student body. 

Submissions by students and staff are awaited and can be submitted as follows:
 
1.       Written submissions
 
The deadline for written submissions has been extended to 12:00 on Wednesday 15 November 2017. Submissions can be sent to news@ufs.ac.za.
