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 Disaster Management Training and Education Centre for Africa (DiMTEC) at our university, recently launched its Art on Disasters initiative at the Gallery on Leviseur in Bloemfontein. 

Disasters have a devastating effect on societies and are accompanied by fear, uncertainties and often post-traumatic stress disorders. The creative arts have the ability to comfort survivors and those affected by tragedy. Amid disaster, art serves as a memorial, aids in the healing process and helps these communities to interpret their emotions. 

This is precisely the main focus of the Art on Disasters project. It aims to develop paintings, sculptures, dramas, theatre productions, poetry and music in collaboration with artists. These productions will then be presented to communities at risk of, or affected by, disasters, to create awareness and foster healing. 

Furthermore, the initiative will conduct research on art as a form of therapy and co-ordinate rehabilitation experts to assist the relevant communities. The artworks collected by the project, will be sold or auctioned to help raise funds. The proceeds will then be donated to a worthy cause as part of DiMTEC’s commitment to community service. 

The project will help console and heal communities and aspire to generate greater resilience to trauma. It will also give humanitarian workers the opportunity to advocate for disaster risk reduction and offer them an opportunity for psychological debriefing after attending to affected communities. 

“We will collect different categories of art related to all forms of disasters. These include paintings, photography, sculptures, poetry, music, theatre productions and short stories,” said Dr Andries Jordaan, Director of DiMTEC. “Stephanie Peters, Thomas Hart Benton, Tania Kovats and Medhi Naimi are just a few of the many artists that paint on man-made and natural disasters. They are artists that believe in art therapy as a form of self-expression, well-being and recovery,” he added. 

For more information about this initiative, or to possibly contribute as an artist, please contact Olivia Kunguma from DiMTEC on +27(0)51 401 9699 or kungumao@ufs.ac.za .
