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.

National Human Trafficking Resource Line a victim-centred approach to combating crime

As a response to the rising number of human trafficking cases in South Africa and around the world, key role players in various fields have pulled together to come up with workable solutions on how to stop the crime and assist victims. Some of the work being done by NGOs and law enforcement agencies has been supported by insights from research conducted in communities and by academic institutions. According to Prof Beatri Kruger, Adjunct Professor of Law in the Faculty of Law at the University of the Free State and experienced researcher in human trafficking, support for victims has grown in leaps and bounds with the help of the latest technology. More and better quality information can be collected to strengthen efforts of combating the crime,” she said.

One such technological development is the national Human Trafficking Resource Line, which provides various services, including information on trafficking activities, assistance to agencies working with victims of trafficking in persons (TIP), creating a network from which data can be collected, analysed, and activities tracked, in order to ensure the best service to victims.

The resource line connects callers, often victims of TIP or anonymous tippers, to service providers in social services, law enforcement, places of safety, medical facilities, and government agencies, especially during emergencies. 

Resource line a helping hand to victims

The resource line was established in 2016 and has replaced the previous helpline. This line provides more services and resources than just a helpline. Through partnerships, it works to strengthen local and national structures that can assist victims over the phone. 

Call specialists are trained by Polaris, an American company using international standards and protocols. The call specialists are available 24/7 to take reports of human trafficking confidentially and anonymously. They put victims in touch with service providers for health screening, counselling, and repatriation if they are from another country, and also assist with case management.

Empowering service providers is the key to success

Support for service providers such as NGOs, safe houses, and government departments in the network is in the form of skills training programmes for staff, and a referral system in various provinces around the country. There are good referral partners in each province, as well as provincial coordinators ensuring accountability regarding cases, mobilising services for victims, and coordinating the referrals and response.  

To strengthen the network further, services provided in each province are being standardised to ensure that the right people are contacted when handling cases, and that key stakeholders in each province are used. The strength of the provincial provider network is key to offering victims of human trafficking the services they need.

Human trafficking is a crime that permeates multiple academic disciplines and professions. Therefore, information collected from victims through such a helpline and collated by agencies, will assist academic institutions such as the UFS in furthering their research, while strengthening the content of academic programmes in fields such as law, law enforcement, social sciences, health sciences, and international relations.

The number to call for reporting or providing tips on TIP-related crimes and activities, is 0800 222 777.
