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.

“I realised the importance of not just accessing the policies and political approaches of the leaders of the apartheid regime, but understanding the ideas and world views that informed them. Part of the solution to this was to learn Afrikaans.”

This is according to Dr Jamie Miller, a Postdoctoral Fellow at the University of Pittsburgh, on how he went about getting inside the mind of South Africa’s apartheid regime in order to complete his book, An African Volk: The Apartheid Regime and Its Search for Survival.

The book was launched on 11 October 2016 by the Archive for Contemporary Affairs at the University of the Free State on the Bloemfontein Campus.

Volk refers to the Afrikaner nationalist movement
The book is an ambitious new international history of 1970s apartheid South Africa. It is based on newly declassified documents and oral histories, the majority in Afrikaans, which focus on the regime’s attempts to turn the new political climate to its advantage.

The term volk refers to the Afrikaner nationalist movement, also known as Afrikanerdom. The story of Afrikaner nationalism was the medium through which the regime gained power.

Four main messages from the book

Dr Miller says there are four main messages for his readers. Firstly, the apartheid regime looked to contest and hijack new ideas and norms that formed the postcolonial world, and secondly, that we need to start thinking more seriously about the Cold War in terms of domestic politics, not just geopolitics.

Thirdly, South Africa should be integrated into histories of the global South, and lastly, we should conceptualise the apartheid regime by looking at it not just as an imperial holdover, but also by looking at what was happening in the world in the time period in question.
