: The domestication of the grey wolf () and subsequent creation of modern dog breeds have significantly shaped the genetic landscape of domestic canines. This study investigates the genomic effects of hybridization and breeding management practices in two hybrid wolfdog breeds: the Czechoslovakian Wolfdog (CSW) and the Saarloos Wolfdog (SAW). : We analyzed the genomes of 46 CSWs and 20 SAWs, comparing them to 12 German Shepherds (GSHs) and 20 wolves (WLFs), which served as their ancestral populations approximately 70-90 years ago.

- Inbreeding depression significantly threatens small populations, leading to harmful mutations and lower survival rates.
- Reinforcement strategies, like translocating individuals from larger populations, can increase genetic diversity and help prevent extinction.
- After translocating Eurasian lynx to the Dinaric Mountains, genetic improvements were noted, but models predict that without ongoing management, inbreeding could recover to critical levels in just 45 years.
Article Synopsis
- The common tern, a migratory seabird, is facing a decline in populations across Europe due to threats like habitat destruction and human interference.
- A study analyzed the genetic structure and diversity of common terns from Northern, Southern Inland, and Southern Marine areas using genetic markers, revealing high diversity overall, but the Southern Marine group had the least.
- The findings suggested weak population genetic structure with high gene flow, indicating that geographical distance between breeding colonies had little impact on genetic differences; the study recommends further research on migration dynamics and conservation efforts for breeding sites.
Integrating data across studies with traditional microsatellite genetic markers requires careful calibration and represents an obstacle for investigation of wide-ranging species where populations require transboundary management. We used the "yardstick" method to compare results published across Europe since 2002 and new wolf (Canis lupus) genetic profiles from the Carpathian Mountains in Central Europe and the Dinaric Mountains in Southeastern Europe, with the latter as our reference population. We compared each population with Dinaric wolves, considering only shared markers (range 4-17).

Earlier analyses suggested that modern grey wolves (Canis lupus) trace their origin to a single Late Pleistocene Beringian population that expanded east and westwards, starting c. 25,000 years ago (ya).
