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.

‘Is the South African university curriculum ‘colonial'?’ asks Prof Jansen

One of the critical issues that emerged from the South African student protests during 2015 and 2016 was a demand for the decolonisation of university curriculums. 

A senior professor at the Stellenbosch University, Prof Jonathan Jansen, said the number of people, including academics, who joined the cause without adequately interrogating the language of this protest, was astonishing. “The role of social scientists is to investigate new ideas … when something is presented to the world as truth.” Prof Jansen was speaking during a celebration lecture at the University of the Free State in Bloemfontein on 15 November 2017. 

Large amount of knowledge not African

He said the accusation is correct to a limited degree. “The objection, in essence, is against the centring of Western, and especially European knowledge, in institutional curricula.” There is no doubt that most of what constitutes curriculum knowledge in South African universities, and in universities around the world, derive from the West. “The major theories and theorists, the methodologists and methods are disproportionally situated outside of the developing world,” Prof Jansen said. 

The dilemma is, how will South Africa and the continent change the locus of knowledge production, considering the deteriorating state of public universities? “In the absence of vibrant, original, and creative knowledge production systems in Africa and South Africa, where will this African-centred or African-led curriculum theory come from,” Jansen asked. He says the re-centring of a curriculum needs scholars with significant post-doctoral experiences that are rooted in the study of education and endowed with the critical independence of thought. “South Africa's universities are not places where scholars can think. South African universities’ current primary occupation is security and police dogs,” Prof Jansen said. 

Collaboration between African and Western scholars
“Despite the challenges, not everything was stuck in the past,” Prof Jansen said. South African scholars now lead major research programmes in the country intellectually. The common thread between these projects is that the content is African in the subjects of study, and the work reflects collaboration with academics in the rest of the world. These research projects attract postgraduate students from the West, and the research increasingly affects curriculum transformations across university departments. There is also an ongoing shift in the locus of authority for knowledge production within leading universities in South Africa. Prof Jansen feels a significant problem that is being ignored in the curriculum debate, is the concern about the knowledge of the future. How does South Africa prepare its young for the opportunities provided by the groundswell of technological innovation? “In other parts of the world, school children are learning coding, artificial intelligence, and automation on a large scale. They are introduced to neuroscience and applied mathematics,” he said.

Prof Jansen said, in contrast, in South Africa the debate focuses on the merits of mathematics literacy, and what to do with dead people’s statues.
