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.

UFS launches focused research niche areas
2009-11-20

The University of the Free State (UFS) will launch its six research niche areas, the Strategic Academic Clusters, from 23-25 November 2009 on its Main Campus in Bloemfontein.

These Clusters represent a move from a fragmented to a more focused approach to research development at the UFS and will in future direct the University’s research endeavours.

“The UFS is increasingly operating in a competitive environment where South African universities no longer compete only with their national counterparts, but also internationally. With the Clusters the University will follow a focused approach to the strategic selection of niche knowledge platforms and research areas,” says Prof. Frans Swanepoel, Director of Research Development at the UFS.

The Clusters are: Water management in water-scarce areas; New frontiers in poverty reduction and sustainable development; Transformation in highly diverse societies; Technologies for sustainable crop industries in semi-arid regions; Materials and nanosciences; and Advanced biomolecular research.

“The Clusters embody the pursuit of quality and excellence and the name signifies the University’s concern not only with research, but also with under- and postgraduate teaching and learning. The vision is that the Cluster activities will not only drive world-class research outputs, but also contribute to internationally renowned graduate programme activities,” says Prof. Swanepoel.

Each of the Clusters is led by a dedicated director who provides academic leadership, facilitates cutting-edge research, leverages multidisciplinary synergies and coordinates the overall Cluster activities.

Next week’s launch programme will start on Monday, 23 November 2009 with a gala dinner, followed by a plenary symposium on Tuesday, 24 November 2009, during which the Clusters will be introduced.

Several national and international experts in the fields covered by the Clusters will take part in this symposium. They are, amongst others: Dr Danny Walmsley from St Mary’s University in Canada; Dr David Wolfe from Cornell University and Dr David Clark from the National Institute of Health, both in the USA; Mr Mark Ashley from the Desert Knowledge Cooperative Research Centre in Australia; Dr Ian Goldman from the Office of the Presidency in South Africa; Prof Peter Ewang from the South African National Development Agency; Mr Willem Louw from Sasol Technology; and Dr Pumla Gobodo-Madikizela from the University of Cape Town.

On Wednesday, 25 November 2009 each Cluster will present its own symposium.
