This research wouldn't have been possible without paw donations from @EssexWildlife, the Cardiff Bio HPC team, and funding from @GW4plusDTP and @EMBO

🧬 While preliminary (n=2), these findings demonstrate the significant potential of museum specimens, and specifically otter hunting trophies, for temporal population genetic studies in this species and system, providing crucial context for contemporary conservation efforts.

📊 We showed that the historical samples cluster with modern Welsh populations rather than with modern east England populations, and don’t show the divergent, Asian, mitochondrial lineage, suggesting any possible Asian introductions likely occurred later.

🔬 Our study examined 2 trophy paws from 1929 and 1952, yielding 77 and 85% endogenous DNA, establishing these specimens as valuable resources for historical genetic research.

It's International Wolf Day today! 🐺 I've been studying wolves for over 10 years now. I wanted to share some facts and findings about one of my favorite populations of wolves -- the Indian wolf.

Brilliant course last week learning all things geometric morphometric - time to start applying it! 💀👩🔬
Geometric Morphometrics in R course completed! 24 students learned and demonstrated landmark-based methods for quantifying and comparing biological shapes. Thanks to Dean Adams & Mike Collyer, GBIF, and KU for their support:)

Congratulations/Llongyfarchiadau to our Otter Project 2024 graduates! @SarahduPlessi16 (second right), completed her PhD using new genomic tools to assess the impact of the population bottleneck on the genetic health of Eurasian otters in Britain and across Europe and Asia.

Sharing this course I'm helping teach at the Smithsonian National Zoo and Conservation Biology institute! 🧬🐺🐻🧬🐦 It's a hands-on course covering conservation genomics, held in October 2024. A few spots still open, and two scholarships available! https://t.co/E1vDXkacRJ

Ever wondered about woolly mammoth jerky? Huge congrats to @jrotwitguez and co-authors on such a cool paper!
It’s finally out! 🥳 Today @cellcellpress we report non-mineral fossils of ancient chromosomes in skin from a woolly mammoth that died in Siberia, 52,000 years ago. 🦣💨 Don’t miss our thread below! 🧵👇🏽

When your collection is older than you are... Huge thanks to all of those who have kept this project running over the past 30 years - what a milestone!
The 3rd of July marks 30 years since the first Cardiff University Otter Project post mortem. 🦦 Thanks to hard work and dedication from staff, volunteers, and supporters, we have come a long way since 1994! 💪 #otterproject #conservation #eurasianotter #postmortem #lutralutra

Tune in to BBC Two at 8pm tonight to hear about how otter skull morphology has adapted in response to feeding ecology, based on our publication which can be found here: https://t.co/bMMdPqtl4d
