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.

Research conducted on economic impact of recent international soccer and rugby matches for Bloemfontein
2004-09-09

The Centre for Development Support at the University of the Free State (UFS) recently conducted a survey on the economic impact of the international soccer and rugby games that were played in Bloemfontein earlier this year.

The research focused on the soccer match between Bafana Bafana and the Cape Verdic Isle and the rugby match between the Springboks and Ireland .

“The survey was done as a result of a research agenda about local economic development in Bloemfontein ,” said Dr Lochner Marais, researcher at the centre.

“We conducted the research by doing 402 interviews with soccer supporters and 376 interviews with rugby supporters from outside Bloemfontein ,” said Dr Marais.

The centre distributed questionnaires, collecting the following information on the soccer and rugby supporters: their age, gender and origin, the number of nights spend in Bloemfontein , their household expenditure in Bloemfontein and their rating on the quality of service.

“It is estimated that 10 800 soccer supporters and 27 000 rugby supporters came from outside Bloemfontein . Of the rugby supporters 14,4% were female and 85,6% were men. For the soccer international the percentage was 33% females and 67% males,” said Dr Marais.

The highest number of people who came to watch the soccer game in Bloemfontein (35,8%) was from the Northern Free State . The rugby supporters mainly came from Gauteng (21,8%) and the Northern Free State (18%).

When visiting Bloemfontein soccer supporters spend R912 per household, whilst rugby supporters reached deeper in their pockets and spent R1 807 per household.

“The survey indicated that the two international matches resulted in approximately R58 million been spent in Bloemfontein . Rugby supporters were accountable for the largest part (R48 787 205) spent. The largest chunk of the money spent was on accommodation (R14 593 279). On average soccer and rugby supporters from outside Bloemfontein spent 1,4 and 1,9 nights in Bloemfontein ,” said Dr Marais.

Rugby and soccer supporters were also asked to rate the quality of service received from amongst others hotels, guest houses, restaurants, and transport and entertainment facilities. Soccer supporters rated their satisfaction with services higher as rugby supporters. The rugby supporters gave the services at hotels a 3,9 rating, whilst soccer supporters awarded 4,6 rating out of a possible five.
