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.

The OSM Camerata (OSMC) of the Odeion School of Music at the University of the Free State ended the 2017 concert season on a high note with two gala concerts presented in the Western Cape as part of the ensemble’s fifth birthday celebrations. The first concert took place at the well-known Hugo Lambrechts Auditorium in Parow on 20 October 2017. A Stellenbosch University audience also had the privilege of listening to the Camerata at Endler Hall the following day.

A substantial part of the concert programme recited during the concerts was dedicated to prolific South African composer, Prof Hendrik Hofmeyr, in honour of his 60th birthday on 20 November 2017. The ensemble recited Super Flumina Babylonis, Notturno Elegiaco & Spokewals/Phantom Waltz - all works commissioned from Prof Hofmeyr for the OSMC.

The Odeion School of Music awarded the Order of the OSM to Prof Hofmeyr during the concert in gratitude for his tremendous contribution as a South African composer.

The final concert at Endler Hall, presented by the Endler Concert Series, was attended by the UFS Rector and Vice-Chancellor, Prof Francis Petersen, and Mrs Cheslyn Petersen.

According to Marius Coetzee from the Odeion School of Music, the OSMC was strategically founded in 2012 as the OSM’s flagship chamber orchestra with its main objective being to create a catalyst for excellence. From a pedagogical perspective, the OSMC serves as an incubator to nurture fully rounded musicians who are thoroughly prepared for the demands of their trade as orchestral musicians, soloists and conductors. 

Responding to the demand for excellence, on 1 September 2017 it was announced that the OSMC received first prize for the 2017 Ictus International Music Competition (US) as the winner of the category for Conservatory and University Orchestras.

Louis van der Watt, head of strings at the University of Stellenbosch Conservatory and vice conductor of the university’s symphony orchestra, remarked that the OSMC presented an excellent concert. Audience members concurred, saying the OSM Camerata was setting new standards for orchestral playing in South Africa.
