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 unique project to honour great teachers
2011-04-21

Dedicated, hard-working, inspiring and motivational ...

These are the kind of teachers the University of the Free State (UFS) is looking to honour in their Great Teachers Project.
 
When one is confronted by most images of teachers in the mainstream media, these are rarely the words that come to mind, though. However, for many young men and women these are exactly the traits which they saw in their teachers, and which inspired them to become South Africa’s next generation of poets, painters, architects, mathematicians, drummers, pilots, lawyers, philosophers, doctors, accountants, community developers and more.
 
One rarely hears about the truly great teachers from our past and present who are the driving force behind the successes of many of our greatest achievers. The teachers who go the extra mile to convey the intricate beauties within their subjects, lead an exemplary life and produced the activists, critical thinkers and leaders we all cherish.
 
Therefore, the UFS and the Sunday Times have joined hands in identifying 150 of the greatest teachers, who moved, inspired and transformed South Africans during their time at school. These are the teachers who stood out among their colleagues and made a lasting impact on their learners, inspiring them to excel, long after the mathematical equations and English literature tests are forgotten.
 
The stories will be collected and assembled on a central database and categorised, edited and represented into a coherent array of powerful accounts of inspired and inspiring teachers.
 
A book entitled Great Teachers will be published in December 2011, detailing the stories of these great individuals. The introduction to the book will present the plan and process that led the storied collection.
Those who are interested are invited to submit a 500 to 750 word essay on any teacher who made an impact in their life and submit it to greatteachers@ufs.ac.za before 30 May 2011.
 
All proceeds from the sales of the book will be used to provide bursaries to student teachers of today, who may become the great teachers for tomorrow’s generation.
