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.

Address by the first Inaugural President of the Central SRC

The UFS Central SRC

Address by the first Inaugural President of the Central SRC of the University of the Free State, Mr Tello Motloung on Wednesday 3 August 2003

The Chairperson of the UFS Council, Judge Faan Hancke,
The Vice-chancellor and Rector of the UFS, Prof Frederick Fourie
The Vice-Rector Student Affairs of the UFS, Dr Ezekiel Moraka
The Presidents of the main campus SRC and the Vista campus SRC
Colleagues in the Central SRC, campus SRCs, students and fellow South Africans

Please receive my heartfelt revolutionary greetings

Vice-chancellor and rector what I bring here with me assisted by facts, is just the work of my imagination. Like a love letter addressed to a sweetheart miles away, even though you do not know how she feels, what she wants to hear, and do not even know what she looks like.

I value speech as just an honest intimation, that’s why I got into a habit of establishing a dialogue with people, looking at each other’s face, and persuading one another of what we are saying.

Vice-chancellor, today marks an important milestone in the history of the existence of the UFS. Today reflects the confidence and trust that students of the UFS have placed in us. They are confident that the Central SRC has both the will and the capacity to take our university forward as we confront the challenge of transformation.

Students are confident that they are correct to trust the Central SRC as the principal agent of change in our university that is genuinely committed to the objective of building a non-racial, non-sexist and democratic university. We need to frankly ask ourselves, as CSRC members, whether are we up to all these challenges?

All Central SRC members have to understand this fully, internalize it, and ensure that everything we do, does not betray the confidence and trust of students, or disappoint their expectations. I say this knowing that all Central SRC members have committed themselves to serve the students of the UFS, black and white, and no one among us (CSRC) needs any special lectures about this central commitment.

The UFS should be an omnibus, welcoming everybody on board. But we should be a bus with a clear direction. We will certainly lose our way if we, as an institution, don’t have a clear road map spelling out where we are heading to.

There should be clear guidelines on the role of students in the transformation process. Students should also be viewed as role players in transformation along with the University management, and not just opposing forces. There is no right time, other than this one, to move away from the politics of opposition to politics of transformation.

However, we need the support of management to do so. The University should value the role and contribution of student leaders, hear our legitimate claims and consider them as part of political and policy decision making.

Vice-chancellor and Rector, it remains our task to ensure that the UFS is transformed into an institution that is seen to be playing a vigilant role in developing students academically, intellectually, socially, culturally, politically and otherwise. The process of transformation is not ending tonight, it is just beginning tonight.

Judge Hancke, Prof Fourie, Dr Moraka, fellow students and fellow South Africans, I lead students at this university with a sense of pride and duty, and I know very well that I lead men and women, students who are all determined that we reach our destination safely and on time.

A navy divided within its ranks will be destroyed and vanquished by the enemy, but the navy united in purpose and action, loyalty and commitment will not sink but sail on to victory.

It is befitting to mention that every drop of my blood is telling me that the UFS is my home. I firstly became a student here, I became the SRC treasurer in my first year here, I became the deputy president here, and I became the first president of the Central SRC of the UFS.

Therefore you should never doubt my commitment towards the transformation of this university. To paraphrase what was said by students at another institution, “If there is no UFS in heaven, then I am not going.”

Let me conclude by thanking my ancestors for teaching me that even if I wined and dined with kings and queens, I am not a king myself, so I should not turn my back on people who made me what I am today.

Most importantly, I would like to thank the Almighty God and the grace of our Lord Jesus Christ for giving me time and power to lead this university.

It will be theoretically irresponsible if I ended my speech without indicating that “Only a Kovsie knows the feeling”.

I thank you.
