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.

Alumni are the heart and soul of a university, a legacy that lives on for generations, bringing pride to the alma mater. Each year, the University of the Free State (UFS) through the Chancellor’s Distinguished Alumni Awards, celebrates its outstanding alumni, who have stood out among their peers, making waves in their careers, at home and abroad. The UFS Chancellor, Dr Khotso Mokhele, said the university plays a pivotal role in ensuring that students enjoy a life-long relationship with their alma mater.  He encouraged the UFS management to create opportunities to engage students during their years of study, in order to create this mutually-beneficial relationship into the future.

The Chancellor’s Distinguished Alumnus of the Year Award, the highest honour accorded to an alumnus, recognises the distinguished national or international achievements of its recipient. The award was presented to Vian Chinner, chief executive officer at Xineoh, a performance marketing company he founded in 2014. The company, based in Bloemfontein, with offices in Cape Town, Oregon in the US, and Vancouver in Canada, specialises in applying mathematical modelling and machine learning to optimise conversion in industries including real estate, mortgage banking and e-commerce. It has generated more than $30 million in revenue for its clients.

The Young Alumnus of the Year Award acknowledges the achievements of alumni who graduated within the past decade and was presented to Leah Molatseli, founder and managing director of Lenoma Legal, who graduated with an LLB at UFS in 2010.

The Cum Laude Award is bestowed upon an alumnus in recognition of excellence in any field, whether vocational or voluntary. The awards in this category were presented to three alumni:

David Abbey, Acquisition and Leveraged Finance Deal Maker at Rand Merchant Bank. David graduated with a BCom Accounting (RU) 2007 and a BCom Hons Accounting (UFS) in 2008.

Johan Eksteen, Agricon Pelleting, graduated with an MSc in Sustainable Agriculture in 1998, and received an MBA in 2005, both at the UFS.

Zola Valashiya, Co-founder and director: Debate Afrika and Schools Projects and Campaigns Manager at Corruption Watch. He graduated with an LLB (UFS) in 2014, and Masters of Public Administration (Central European University, Hungary) in 2016. He is a Mandela Rhodes Scholar (2015) and a Young African Leadership Initiative Mandela Washington Fellow (2017) and is presently featured on the Mail & Guardian list of top 200 young South Africans.

The Executive Management Award:
this service award is presented to an individual who has delivered exceptional service to the UFS and is not limited to alumni of the institution, current students and the community at large. The award was presented to Sarina Cronje, Head of Athletics at KovsieSport.

She graduated with a Bachelor of Science (UFS) in 1977 and a Postgraduate Diploma in Higher Education (UFS) in 1983. She is a mother and career woman, whose family carries the same passion and drive for sports that champions are made of.

The Kovsie Ambassador Award is bestowed upon a current student whose achievements have brought him/her distinction, benefited his/her community, and brought credit to the UFS.

Crystal-Donna Roberts graduated with a BA Drama and Theatre Arts (UFS) in 2005. She is an active television, theatre and film actress who has appeared in a multitude of theatre productions in addition to starring in Afrikaans soap opera “7de Laan, Getroud Met Rugby, Montana” and “Vallei van Sluiers” in which she won public favour. She is currently playing the lead role in the internationally acclaimed film, “Krotoa” which has won numerous awards including Best Film at the Harlem International Film Festival in New York. It also won the Award of Excellence at the International Film Festival for Women: Social Issues and Zero Discrimination, and many more.

Franco Smith, Director: Free State Rugby and Assistant Coach: Springboks. He graduated with a BA Human Movement Sciences (UFS) in 1996 and began his career in rugby in 1999 when he was selected for the Free State Under-18 Craven Week team. He became a regular on the Free State Under-20 and the UFS Shimlas teams prior to his Free State Cheetahs debut in 1992. Franco was reappointed backline coach of the Cheetahs and head coach of the Shimlas in 2015. With many accolades to his name an illustrious career in coaching and management over the years, the name Franco Smith should not be foreign to true rugby connoisseurs.

The Rector and Vice-Chancellor, Prof Francis Petersen, congratulated all the award recipients: “I applaud all alumni; you have made the city of Bloemfontein and the whole province proud.” The National Executive Alumni Chairperson, Dr Pieter du Toit, congratulated the award recipients and thanked the leadership of the university as well as the event organisers. 

The awards signify the great esteem with which the UFS holds its alumni and the community that helps to drive its vision, cherish its history and pave the way for more outstanding Kovsies of the future.
