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.

Andrew Mellon Foundation renews ongoing support for UFS projects
2017-04-10

Description: ' Andrew Mellon Foundation - Badat Tags: Andrew Mellon Foundation - Badat

Dr Saleem Badat and Annemia van der Heever.

The University of the Free State (UFS) was first awarded a grant by the Andrew W Mellon Foundation (AWMF) in 2015 to fund several projects between 2015 and 2016 under the International Higher Education Strategic projects fund. The programme’s director, Dr Saleem Badat, visited the UFS on 23 March 2017 as part of his annual first-quarter feedback sessions, with not only the UFS but other universities around the country that benefited from the programme. Top of the agenda was a meeting with principal investigators of projects funded by the foundation, to discuss the UFS’s institutional priorities for funding, alongside the university’s management, to discuss possible intra-institutional projects to be undertaken with other universities.

During his visit, Dr Badat met with Prof Nicky Morgan, UFS Acting Vice-Chancellor and Rector, as well as the AWMF representative, Annamia van der Heever, Director: Institutional Advancement. He discussed future plans with managers of the Programme for Innovation in the Artform Development, #Movements project, Inclusive Professoriate Grant and the Curriculum reform programme which involved seven other universities.  

The AWMF, through its projects, is instrumental in developing and maintaining strong higher education institutions that produce knowledge and high-quality graduates, and advances social justice. The projects further aim to deepen and broaden public understanding and support for the arts and humanities, diversity and inclusion. “The Foundation each year presents universities with wonderful opportunities to improve teaching, learning and research in the humanities. We are working hard with the Faculty of Humanities on possible submissions for 2017,” said Van der Heever.

During 2017 between $10.8 million and $12 million will be available for grants by the Foundation’s International Higher Education and Strategic Projects programme. The Vice-Chancellor’s Office will continue to serve as a contact point and administrative support for UFS projects currently funded by AWMF. Institutional Advancement will assist project leaders to draft submissions to the Foundation this year and in the future. In 2018 AWMF will celebrate 30 years of involvement in supporting higher education in South Africa.
