At DivjaLabs, we are proud that our team members Elena Pazhenkova, Barbara Boljte, Marjeta Konec, Astrid Vik Stronen and Tomaž Skrbinšek, alongside international collaborators, have led a significant study on the genetic rescue of the Dinaric lynx population. This research has just been published in the esteemed journal Evolutionary Applications. The study not only advances our understanding of genetic rescue in conservation biology but also serves as a powerful example of successful international cooperation for conservation.
A conservation crisis: The Dinaric lynx
The Dinaric population of Eurasian lynx (Lynx lynx), reintroduced in 1973, has faced severe challenges due to its small founding population and geographic isolation. Over time, inbreeding depression and genetic erosion threatened its survival. By 2019, the effective inbreeding coefficient exceeded 0.31—a critical threshold comparable to exclusive sibling mating. Without intervention, the population faced the imminent risk of re-extinction.
The LIFE Lynx project
Our study documented the implementation of genetic rescue efforts through the translocation of 12 lynx from the Carpathian Mountains to the Dinaric Mountains in Slovenia and Croatia between 2019 and 2023. These actions were part of the LIFE Lynx project, funded by the EU LIFE program and Slovenian Research and Innovation Agency, with the goal of countering inbreeding and boosting genetic diversity.
Key findings
- Genetic improvement: The translocations significantly reduced inbreeding levels, bringing effective inbreeding down to 0.18 in the short term.
- Population viability: Stochastic modelling predicts the reinforced population will remain viable for about 45 years, with ongoing genetic management necessary to prevent a return to critical inbreeding levels.
- A model for the future: The study provides a template for conservation strategies in similar contexts, emphasizing the importance of sustained genetic monitoring, population connectivity, and long-term planning.
Beyond genetics: The role of collaboration
This work highlights the value of multidisciplinary collaboration. Contributions from scientists, conservationists, local communities, and policymakers were essential in ensuring the success of these efforts. Transparent communication and community engagement have helped garner support and reduce human-related threats to the lynx.
Looking ahead
The Dinaric lynx story is far from over. While the reinforcement has bought valuable time, ensuring the long-term survival of the population will require:
- Regular genetic monitoring and further translocations.
- Restoring habitat connectivity to facilitate natural gene flow.
- Continued collaboration with stakeholders to minimize human impact.
Our study underscores that conservation is a continuous process, blending science, policy, and community action.
A global lesson
The genetic rescue of the Dinaric lynx population demonstrates that proactive genetic management can reverse alarming trends in endangered populations. We hope this work inspires and informs future conservation efforts worldwide.
