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.

Out-of-the-box thinking a plus for next generation of agribusiness leaders

The International Food and Agribusiness Management Association’s International Student Case Competition, in its 12th year, brings together students from around the world to demonstrate their investigative and problem-solving skills to provide innovative solutions to practical problems.

JW Swanepoel, a PhD student at the Centre for Sustainable Agriculture at the University of the Free State (UFS) was part of an advanced case study team, representing South African universities, who won IFAMA’s International Student Case Competition. Swanepoel also presented results from his PhD study at IFAMA’s conference in Miami, Florida, where the winners were announced.

Competition a global stage to showcase solutions

The competition provides a global stage for students and their associated universities to showcase the next generation of agribusiness leaders.

This year the featured agribusiness was Bayer Crop Science. Although this company managed to expand its global footprint through its Food Chain Partnership, it faced some challenges to expand in emerging economies through small-scale farmers. Being from the African continent, Swanepoel and his team not only understood Bayer’s unique challenge but could also pre-empt some of the potential problems faced by agribusinesses that wanted to grow their footprint in emerging economies. This provided them with a competitive advantage in going head-to-head with some of the best universities in the world such as Purdue, Wageningen, Michigan, Texas A & M and Santa Clara to mention just a few.

The South African team’s presentation “Selling Lindiwe’s story” told the story of a small-scale woman cassava farmer in Mozambique who, after the death of her husband, became the main breadwinner. The South African team indicated how Bayer could play a major role in not only selling chemicals to these farmers but even more importantly to change the stories of small-scale farmers like Lindiwe. They recommended a strategic partnership with AB InBev as the main buyer for the cassava produced by these small-scale farmers, as a cheaper beer base substitute. They also recommended a local partner (Value Chain Insights) that understood the political, social and economic environment of these countries to facilitate the relationships between Bayer and its small-scale farmers.

Understanding the challenge a competitive advantage

According to the panel of judges, the innovative approach and motivations for investing in strategic partnerships with AB InBev and Value Chain Insights went beyond financial benefits, to include corporate social responsibility and rural development. Lindiwe’s story was, however, the decisive factor. The South African team was the only team to put a face and a story to the often invisible small-scale farmers.
