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.

Learning from industry experts is essential for students’ development. When that learning eases the financial burden of tuition fees, it is even better. TATA Africa has ensured that students from the University of the Free State (UFS) earn academic currency for displaying leadership and business skills.

Jehan Van Vuuren walked away with R40 000 in his student account, Hendrike Prinsloo earned herself R30 000, Stephan Strampe has R25 000 less to worry about when the 2016 academic year arrives, and seven other students managed to save their parents R20 000 each.

These top 10 Strategic Marketing students from the UFS Department of Business Management and Department of Communication Science took up the challenge of devising strategic concepts to be implemented by the Africa branch of TATA Group companies.

TATA Group is a multinational conglomerate which specialises in a wide range of products and services, such as automobile manufacturing, hotel accommodation, construction, textiles, food and beverages, amongst other enterprises operating under its banner. On 15 October 2015, the company’s Head Office representatives signed a cheque for R275 000 to reward the creative input of our students.

Lesle-Ann George won an academic bursary worth R20 000 for her individual effort, and was also part of one of the best four groups that won R10 000 each. She said the competition was an opportunity of a lifetime. The financial aid will be channeled towards the BCom Marketing Honours degree she intends pursuing next year.

The students’ ideas included market research for TATA motors, the development of a mobile application for the Taj Hotel, as well as innovative student-oriented social media, and guerrilla marketing strategies.

“This collaborative partnership between TATA Africa and UFS has provided the students with an opportunity to learn from key role-players in the industry and, in turn, to gain practical exposure to real-life industry happenings,” said Naquita Fernandes, a Business Management lecturer and the competition’s co-organiser.
