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.

UFS changes format of graduation ceremony

2011-04-17

The highest number of qualifications in the history of the University of the Free State (UFS) will be awarded at the autumn diploma and graduation ceremony from 9-11 May 2011, which will be held in the Callie Human Centre on our Main Campus in Bloemfontein.

From this year, the format of the ceremony will change to make it more visible to students and the public. For the first time, all the doctoral and master’s degrees from each respective faculty will be conferred during one ceremony on 11 May 2011, instead of each faculty handling these qualifications individually. Another change in the format is that the procession will gather on the Red Square in front of the Main Building and move to the Callie Human Centre from there. Both academic staff and graduands will partake in the procession.

A total of 3 674 qualifications will be conferred during this year’s graduation ceremony, including 629 diplomas, 2 613 Bachelors and honours degrees, 372 master’s degrees and 58 doctorates.

An honorary doctorate in Drama and Theatre Arts will also be awarded to theatre stalwart Mr Pieter Fourie. He is one of the most acclaimed Afrikaans playwrights in South Africa and probably the only person to have left his mark as an actor, director, artistic director and writer.

Mr Fourie was awarded the Gerhard Beukes prize for drama , was honoured for his contribution to the arts by the South African Academy for Science and Arts and was appointed as trustee of the Arts and Culture Trust of the State President in 1997. He has also served as a committee member of the South African Academy for Science and Arts.

Mr. Fourie has also been the proud recipient of the Hertzog prize for drama, two FNB-Vita awards and a Fleur Du Cap award.

The full programme for the respective ceremonies is as follows:

Monday, 9 May 2011:

At 08:30, certificates and diplomas, excluding PGED and PGES, will be awarded to graduates from the Faculty of Education and at 12:00 PGED, PGED and B and honours degrees will be awarded to students from the same faculty. At 15:30 on the same day, certificates and B and honours degrees will be awarded to students in the Faculty of the Humanities.

At 19:00, the Faculties of Education, the Humanities and Economic and Management Sciences will have their prize-giving ceremonies for outstanding achievers.

Tuesday, 10 May 2011:

At 08:30, students in the Faculty of Economic and Management Sciences will graduate and at and 12:00 the Faculty of Natural and Agricultural Science will join them. This includes students in BML, B.Admin., B.Pub. and related honours degrees. At 15:30, 503 students from the Faculty of Natural and Agricultural Sciences will receive their certificates, diplomas and B and honours degrees.

At 19:00, the Faculties of Health Sciences, Natural and Agriculture Sciences, Law and Theology will have their prize-giving ceremonies.

Wednesday, 11 May 2011:

The Faculty of Health Sciences, the Faculty of Law and the Faculty of Theology will be awarding their certificates, diplomas and B and honours degrees at 08:30. At 12:00, all faculties will award a total of 372 master’s degrees and at 15:30 a total of 58 doctorates will be conferred.

The Chancellor’s Dinner will take place in the Centenary Complex on the Main Campus of the UFS at 19:00.

The graduation ceremony of our Qwaqwa Campus will take place in the Rolihlahla Mandela Hall on the Qwaqwa Campus on 7 May 2011 at 10:00. All the faculties at this campus will confer their degrees, certificates and diplomas at this ceremony.
