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 hosts a successful New Music Indaba
2015-08-18

  

Held at the University of the Free State’s Odeion School of Music (OSM), the NewMusicSA’s New Music Indaba 2015 featured works which Clare Loveday described as “breathtaking, discreet, and perfectly balanced.”

Loveday, one of South Africa’s acclaimed music critics and was Composer-in-Residence for the annual Johannesburg International Mozart Festival, attended the Indaba from 21-26 July 2015. In a review of Saturday’s gala concert, she referred to recitals of this nature as an “essential part of the South African musical landscape, providing musicians and composers a space in which to express their world.”

Staff and students of the OSM were extensively involved in facilitating the festivities as a symbol of commitment to South Africa and international contemporary art music. The OSM Camerata under the baton of Xavier Cloete performed two works by South African composer Hendrik Hofmeyr well as a work by young Argentinian composer Diego Soifer entitled Mille Regretz .The festival featured music theory lectures, a variety of workshops, roundtable discussions ,concerts as well as an outreach programme.

Loveday described the highlight of her Indaba experience as “A delicate construction of sounds and silences that drew the listener into a focused and intense sound world,” a highlight created by the visiting German composer, Charlotte Seither’s “Far From Distance” for piano, clarinet, and cello. The concert evening culminated with Diale Mabitsela's "Friday Nights at Six," adding to the spectacular nature of the festival.

Throughout the week, classical chamber works featuring South African New Music Ensemble (SANME), the Choir of Christ Church Arcadia, and the Odeion Vocal Consort were performed and well-received. Bringing the five-day event to a conclusion was a choral mass at the Bloemfontein Anglican Cathedral, featuring an “Agnus Dei” written by George T. King.
 
Douglas Scott, Curator of the 2015 Indaba, reflected on it as a great success, saying that, “most of the participants agreed the event was a wonderful opportunity simply to hear different voices from the composition community juxtaposed with one another.”

From Scott’s perspective, the principal goal was to foster communication between artists with different visions, and to reach out to the local community.
