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.

 In the short space of five years, the Centre for Business Dynamics at the University of the Free State (UFS) has grown in stature to such an extent that it is currently offering leadership development programmes at 45 institutions all over the country.

Speaking at the fifth anniversary of the centre’s establishment, its director, Mr Danie Jacobs, said the centre was the first commercial unit in South Africa, attached to a business school, to establish a desk focusing on Black Economic Empowerment (BEE) and Transformation in association with Empowerdex.

The main purpose of this joint venture with Empowerdex is to deliver comprehensive BEE training through the development and presentation of various programmes.

The centre has also introduced the High-Performing Directors’ Programme in association with ABSA. A total of about 40 students have enrolled for this programme so far,and their numbers fluctuate every year.

It is also the first unit in the country to link up with Thinking Fusion, one of the three consultancies contracted by the UFS, to introduce two unique leadership programmes, namely a programme in Creating Leadership and Personal Capacity in Women and the Leadership in the Connection Economy programme.

“Our aim is to prepare women for full participation as managers and leaders in transforming organizations to become truly integrated and representative of the full diversity spectrum of South Africa,” Mr Jacobs said.

“We have built amazing relationships with various clients, both in the private and public sector, over the last five years,” said Mr Jacobs. “I believe the success of the Centre for Business Dynamics lies within our methodology of action learning, as well as creating a learning path for working adults.”

“Because of our country’s history not all people are on an equal footing when it comes to prior learning, so we level the playing field by breaking the training up into easily absorbable components. The centre can address the training needs of any company because of the multiple resources that we are fortunate enough to have at our fingertips,” he said.

The centre also offers a Postgraduate Diploma in Tax Strategy and Management, aimed at bringing all parties involved in the field of taxation up to date with the latest developments and changes.

In addition, the centre has introduced The Choice and The Choice at Work programme in association with the Arbinger Institute in the United States of America. There are also two management programmes, namely the Management Preparation Programme and the Management Development Programme.

Apart from these programmes, the centre also offers products and services such as short courses, workshops and consultations.
