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.

Council on Higher Education LLB qualification review not yet complete
2017-05-16

The reaction from various stakeholders following the ‘Outcomes of the National Review of the LLB Qualification’ by the Council on Higher Education (CHE) on 12 April 2017 requires the CHE to clarify that the national review process has not been completed and is ongoing.

The peer-review process conducted under the auspices of the CHE is based on the LLB Standards Document which was developed in 2014-2015 with input from higher-education institutions and the organised legal profession. Following self-review and site visits by peers, the process is now at the point where commendations and shortcomings have been identified, and the statement of 12 April reflects those findings. All law faculties and schools have been asked to improve their LLB programmes to meet the LLB Standard, and no LLB programme has been de-accredited. All institutions retain the accreditation they had before the Review process began and all institutions are working towards retaining their accreditation and improving their LLB programmes.

The South African Law Deans’ Association (SALDA) has issued a set of responses regarding the LLB programme review. The following questions and answers were published to give more clarity on the questions raised.

1.    What is the effect of a finding of conditional accreditation?
The programme remains accredited.

(“Accreditation refers to a recognition status granted to a programme for a stipulated period of time after an HEQC evaluation indicates that it meets minimum standards of quality.”)

The institution must submit a progress report by 6 October 2017 that indicates how short-term aspects raised in the HEQC reports have been addressed and an improvement plan to indicate how longer-term aspects will be addressed.

2.    What is the effect of a finding of notice of withdrawal of accreditation?
The programme remains accredited.

The institution must submit an improvement plan by 6 October 2017 to indicate how the issues raised in the HEQC report will be addressed, including time frames.

3.    How does the finding of notice of withdrawal affect current students?
Students currently enrolled for the LLB programme at any institution are not affected at all. They will graduate with an accredited qualification.

4.    How does the finding of notice of withdrawal affect new applicants?
The programmes remain accredited and institutions may enrol new students as usual. This also includes students completing BA/BCom (Law) programmes who wish to continue with the LLB programme.

5.    How does the finding of notice of withdrawal affect prior graduates?
Degrees previously conferred are not affected.

6.    What happens when the improvement plans are submitted in October 2017?
The CHE will evaluate the plans when they are submitted, and the programmes remain accredited until a decision is taken whether the improvement plan is sufficient and has been fully given effect to or not. The institutions will have to submit progress reports to the CHE indicating implementation of measures contained in the improvement plan.

Should a decision at some stage be taken that a programme’s accreditation must be withdrawn, a teaching-out plan would be implemented so that all enrolled students would have the opportunity to graduate with an accredited degree.
