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.

South Campus delivers out-of-the-box solutions

The IDEAS Lab on our South Campus supports learners in 83 schools by means of academic videos transmitted via the Internet Broadcast Project (IBP) and its own custom-built All-in-One (AIO) device. The project is a collaboration between UFS and the Department of Education in the Free State. It includes support for Mathematics, Physical Science, Life Science, Economics, Accounting, and Geography.

The AIO was purpose-built by the team at IDEAS Lab to facilitate the delivery of video lectures from highly-qualified teachers to identified schools. It comprises a projector, speakers, and a computer, which are housed in a custom-made, hard-wearing frame. The AIO is then set up at each school to which lessons are broadcast.

On-the-job training for educators

Educators have not been overlooked, either. UFS was the very first university to provide an Advanced Certificate in Teaching in a fully digital format, the ACT Online programme. It is designed for practicing teachers to upskill themselves in order to better address the needs in the classroom, not only advancing their career, but strengthening their knowledge, competencies, and subject specialisation as well. Ultimately, this leads to an improved quality of education, which has a profound impact on multitudes of students around South Africa.

CSIR joint initiative

Coupled with these projects is a new joint initiative termed ICT For Education. This project sees the CSIR collaborating with the national Department of Education, the Department of Rural Development and Land Reform, and the UFS. For this project, 24 primary and secondary schools in South Africa were identified to promote technological advancement in the education sector. Tablet computers have been allocated and already deployed at these schools, to learners as well as nearly 400 teachers.

South Campus is involved in the training of the teachers and learners in the use of the tablets in the classroom and other educational opportunities. In addition, training for 48 unemployed young people who will be providing first-line support began in March at a school in Thaba Nchu. The course on IT support is structured in such a way that anyone in the community can take it, starting out with topics such as My role in the community.
