We found moderate inbreeding levels in the Tiritiri Matangi population that is associated with lower reproductive success, indicating inbreeding depression (ID). ID in the hihi is likely polygenic in nature including two potential regions harbouring genes related to reproduction in other birds.

New Zealand’s invasive starlings on the cover of Molecular Ecology! 🐦🧬
This collaborative project unpacks the invasion history of starlings in Aotearoa New Zealand, combining population genomics with historical records of human-mediated translocations.

💡 Bonus: Open Snakemake pipelines for both simulation and imputation are provided:
- github.com/vibaotram/si...
- github.com/vibaotram/im...
Feel free to test and optimize imputation strategies for your own datasets before committing to large-scale LCS projects.
👩🏻💻 We tested 5️⃣ imputation methods (GLIMPSE2, GeneImp, QUILT2, STITCH, Beagle5.4), simulated realistic populations with different genetic structures, and applied the methods to data from 283 wild hihi (stitchbird) 🧬.
