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 Department of Architecture Building receives SAIA Award
2014-08-21

 
The South African Institute of Architects (SAIA) conferred a national merit award on renovations and additions to the DHET UFS Department of Architecture Building. The UFS is very proud of this award.

The building, which was completed in 2012, was designed by Typology Architects' director, Henry Pretorius. Pretorius is also the Head of the Department of Architecture at the UFS.

“The merit award by the South African Institute of Architects, which was presented on 1 August 2014 at the International 2014 UIA congress (held for the first time in South Africa), is a great honour. Not only does the award recognise my work as an architect, it also brings back a certain degree of pride to the Free State and especially the UFS’s Department of Architecture,” says Pretorius.

The SAIA Awards Programme runs over two years to coincide with the presidential term of office, starting with the Regional Awards for Architecture during the preceding year.

A total of forty-nine (49) entries for varying buildings were received from the regions. The project range included residential projects, new public buildings, restoration of heritage projects and an academic research project.

From these submissions, fourteen (14) projects received merit awards, of which eight (8) projects received excellence awards.

The adjudication panel comprised:
• Sandile Ngonyama: SAIA President
• Paul Kotze: Architect, planner and academic from WITS
• Malcolm Campbell: Architect from ACG Architects in Cape Town
• Annemarie Meintjies: Deputy editor of VISI magazine, representing a prominent member of the public
• Peter Kidger: representative of Corobrik, sponsor of the awards.
