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.

The newly elected Chairperson of the UFS Council, Mr Willem Louw, and Prof Francis Petersen, the incoming Vice-Chancellor and Rector of the UFS, were welcomed at this year’s official opening of the academic year which took place at the Bloemfontein Campus of the University of the Free State (UFS) on 3 February 2017.  

Prof Petersen, who will start his tenure at the UFS on 1 April 2017, was introduced to staff by the Acting Rector, Prof Nicky Morgan. Prof Petersen shared his future plans for the UFS with staff.

His vision for the UFS spells excellence. Among others, he seeks to establish an academic culture of excellence, underpinned by the pillars of diversity and inclusivity. “It is important that there should be respect for different convictions,” he said.

“The UFS should be a place where everyone feels welcome; a strong sense of belonging is needed. Staff and students should feel that they would like to make a contribution to make the UFS a strong university,” he said.

In order to address the institutional climate issue, Prof Petersen suggests that attention be given to the curriculum as well as transformation of the research culture. Research outputs should be expanded and diversified. Inclusivity from a community engagement perspective is also needed. “The things we are good at and in which we excel should be the anchors impacting our academic enterprise,” he said.

In terms of the physical environment, he said that spaces should be welcoming for students. “It is important that we sit with students to get their views and listen to their concerns,” Prof Petersen said.

To promote transformation at the university, the UFS management team is busy working on an integrated transformation plan to be submitted to Council in June 2017. As part of this process, consultations will be held with staff and students in order to incorporate their perspectives and convictions in the plan as well.

“It is important that there should be
respect for different convictions.”

Furthermore, it is important for Prof Petersen that the Qwaqwa and South Campuses should be more integrated with the Bloemfontein Campus. “The UFS is one university with three locations. The fact that it is one university should be reflected in our actions, attentions, and thoughts. Although there are geographical differences, all three campuses should receive the same resources and should deliver the same quality outputs,” he said.

Prof Petersen ended his speech by returning to the importance of academic excellence. “With the Academic Project we always strive for excellence. To achieve academic excellence, the focus is on both academic and support staff. In order to reach our goal, all staff should produce work of superior quality,” he said.

“I am a good listener who is outcome driven, with a vision that includes: diversity, inclusivity, academic excellence, and innovation”, Prof Petersen concluded.
