Students hear from textbook writer about conservation genetics

Genetics lecture — Alistair Naidoo, second-year master’s student in Conservation Genetics and full-time technician in the Department of Genetics; Prof Paul Grobler, Head of the Department of Genetics; Prof Gordon Luikart; and Hannah Janse van Vuuren, third-year master’s student in Conservation Genetics.

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.

Faculty of Law establishes unique panel of advisors

Some of the panel members who attended the Collegium Iurisprudentium of the Faculty of Law at the UFS were from the left His Honorable Judge of Appeal Lex Mpati (Vice-President of the Supreme Court of Appeal), His Honorable Judge of Appeal Joos Hefer (former Chief Justice of South Africa), His Honorable Judge of Appeal Frits Brand (Supreme Court of Appeal) and Mrs Alet Ellis (lecturer at the UFS Faculty of Law).

At the back from left were Prof Johan Henning (Dean: Faculty of Law at the UFS), His Honorable Judge Faan Hancke (High Court of the Free State and chairperson of the UFS Council) and Adv Jannie Lubbe Sc.

The Faculty of Law at the University of the Free State (UFS) has established a panel of advisors comprising of all the honorary and extraordinary professors of the faculty.

“The faculty has been known for its excellent practice-orientated training as well as the involvement of law practitioners in the training of LL B-students,” said Prof Johan Henning, Dean of the Faculty of Law at the UFS.

“The faculty was greatly dependent on the services of advocate lecturers, full-time members of the Bar and Side Bar who lectured on a part-time basis at the faculty. For this reason lecturing in the faculty was mainly done after-hours to part-time students,” said Prof Henning.

With the shift in emphasis to full-time lecturing and the appointment of full-time lecturers, especially because of the increasing student numbers, the full-time LL B-programme and the increasing pressure on students for quality research inputs, a greater need for meaningful contributions of judges and senior law practitioners to the faculty was experienced.

“To comply with this urgent need, three honorary professors and nine extraordinary professors were appointed. This group of experts deliver an indispensable contribution to the practice orientation of the faculty by means of formal lectures, public inaugural lectures and guest lectures, direct lectures to graduate and post-graduate students, participation in research projects and the constant evaluation of lecturers, modules and the content of modules and learning material. The international exposure of students and lecturers is also promoted by their contribution,” said Prof Henning.
“A need to have the involvement of this special class of professors structured in a more organised way was identified and a decision was made to establish an advisory panel called Collegium Iurisprudentium. It is a privilege to us that all the honorary and extraordinary professors accepted the invitation,” said Prof Henning.

The panel will provide the faculty with continuous, distinguished, practice- orientated capability and capacity as well as international expertise, not only for direct inputs to students but also to advise lecturers about the curriculum, the compilation of the content of the LL B and M module, learning material and others, as well as to strengthen the research capacity of the faculty.

“The panel will also deliver a decisive contribution to the faculty’s preparation for the constitutional audit of the Higher Education Quality Committee (HEQC) of the Council for Higher Education (CHE) that will take place in October 2006,” said Prof Henning.

The Collegium Iurisprudentium, which has been formally constituted, comprises of:

Appeal Court Judge J J F Hefer,
Appeal Court Judge L Mpati
Appeal Court Judge F D J Brand
Appeal Court Judge I G Farlam
Prof B A K Rider
Judge S P B Hancke
Judge A Kruger
Judge D H van Zyl
Adv S J Naudé
Adv J Lubbe Sc
Prof M M Katz
Prof R J Cook
Mr S van de Merwe
Mr W van der Westhuizen
Mr D C M Gihwala
