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.

CHE lifts notice of withdrawal of UFS LLB degree’s accreditation status
2017-11-16


The Council on Higher Education (CHE) has lifted the notice of withdrawal of the accreditation status of the University of the Free State’s (UFS) LLB degree. The degree is conditionally accredited with a progress report required in October 2018.

The Faculty of Law received this response to its Improvement Plan for the LLB degree from the CHE on 14 November 2017.

During 2016, a national review was conducted on all LLB programmes in order to strengthen the quality of legal education provision at all South African universities. On 30 March 2017, the Higher Education Quality Committee (HEQC) approved the findings of the National Reviews Committee (NRC) with regard to the LLB programme at the UFS, and placed the qualification on a notice of withdrawal of accreditation.

The decision of the CHE this week comes after the faculty submitted the Improvement Plan during early October 2017. This plan sets out for the CHE the changes that will be effected in the LLB programme for 2018 and 2019 and provides an outline of the new LLB curriculum it intends to introduce in 2020.

“The university’s executive management is extremely pleased about the outcome and welcomes the lifting of the notice of withdrawal of accreditation status, as it comes during a critical time of the year when the new cohort of Law students is completing their Grade 12 exams. Prof Caroline Nicholson, Dean of the Faculty of Law, and her team are commended for the considerable effort put into the submission and the extensive attention that was specifically given to concerns raised by the CHE in terms of the number of credits in the degree,” says Prof Francis Petersen, Rector and Vice-Chancellor of the UFS. 

“There is hard work to be done going forward in ensuring that the UFS LLB degree is the very best on offer in South Africa, but with the continued support and commitment of the staff and students in the Faculty of Law, this vision is achievable,” says Prof Nicholson.
