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 Library book launch programme fosters dialogue between students and authors

The University of the Free State (UFS) Sasol Library has hosted a series of book launches since 2016, bringing to the Bloemfontein Campus various new and seasoned authors who share their stories with the campus audiences. The Launch Your Book at the Library Programme hosted two authors on 23 March 2017, Itumeleng Sekhu and Marcia Ramodike. Both authors spoke about their life-changing experiences and shared their heart-wrenching stories, filled with courage and hope. 

“Libraries must take the lead in creating dialogue, expression of ideas and inculcating a culture of reading and writing. This programme was also established to bridge the gap and find ways to encourage students to read and write, by creating a platform where they can interact with authors and see that people who write books are ordinary people with real stories to tell,” said Marcus Maphile, Assistant Director: Library Marketing and Community Engagement.

Speaking about her book, Itumeleng Sekhu described her experiences from childhood and her life as a disabled person after being severely burnt in a fire accident in her home as a baby.  She said: “I tried to commit suicide several times because I had lost hope. Eventually after failing to do so, I realised at some point that it was time for me to let my light shine through.” She wrote her book, titled What Do You See?, which has received substantial media coverage, to encourage others who live with painful experiences, disabilities and what she terms “internal wounds”, hoping that her experiences could help to heal them.

Marcia Ramodike’s book, An Empty Pride to a Full Price, paints a picture of her life as a youth grappling with adult issues. She describes her pain after her mother’s death, and her constant battle with the legacy of the difficult socio-economic conditions she grew up in. When students asked Ramodike what she thought the right time was to write a book, she responded, “today is the right time to write your story”.

The UFS Library has hosted 16 book launches since 2016, with the biggest being the launch of Zubeida Jaffer’s book Beauty of the Heart. The programme aims to provide access to information and to share and debate ideas in support of democracy and freedom of speech.
