Exploring genomic rewilding: DivjaLabs’ co-founder contributes to important research

On January 28, 2025

At DivjaLabs, we are committed to advancing scientific understanding of biodiversity and genetics, and we are thrilled to celebrate the recent publication co-authored by one of our lead scientists and co-founder, Astrid Vik Stronen. This important study, titled "Genomic Rewilding of Domestic Animals: The Role of Hybridization and Selection in Wolfdog Breeds," was published in the prestigious journal Genes in January 2025.

A deep dive into genomic rewilding

The study focuses on wolfdog breeds, specifically the Czechoslovakian Wolfdog (CSW) and Saarloos Wolfdog (SAW). It explores how hybridization and selective breeding have shaped their unique genetic profiles, combining traits from domestic dogs and wolves. This work sheds light on how controlled hybridization can enhance genetic diversity, offset inbreeding, and contribute to the long-term health of these breeds.

Key findings and their significance

  1. Hybridization as a tool for diversity: The research highlights how careful integration of wolf genetics into dog populations can increase heterozygosity and maintain robustness, offering lessons for conservation and breeding practices.
  2. Inbreeding challenges: The study found that the Saarloos Wolfdog, despite its genetic heritage, has experienced significant inbreeding, emphasizing the need for sustainable breeding strategies.
  3. Genetic insights: The analysis uncovered distinctive genetic markers in both breeds, showing clear differentiation from their ancestral populations of German Shepherds and wolves. These findings underscore the importance of historical breeding decisions in shaping modern-day wolfdog breeds.

The broader implications

This research exemplifies the concept of genomic rewilding, which aims to reintroduce wild alleles into domesticated species to boost their genetic health. Such approaches could revolutionize conservation strategies and provide solutions to genetic bottlenecks in both wild and domesticated populations.

A proud moment for DivjaLabs
