The #IUCN Conservation Genetics Specialist Group (which I am proud to be part of) has a new website up, see below. Beginning to add resources, and also highlights our members across the globe. We hope this resource will help others reach out to us to input or advice.

Our new paper on mitogenome sequences from otter spraint, with Sarah and Jenny as joint first authors, has been featured in an article by phys.org!

Very glad about this new paper by former Cardiff Uni @one-cardiffuni.bsky.social PhD student Annalea Beard @annaleabeard.bsky.social come out in #MovementEcology. Documenting very different foraging behaviours and ranges in cool versus hot season breeding populations #stormpetrels from #StHelena.

Haplotype A haplotype is a set of DNA variations, or polymorphisms, that tend to be inherited together.

a link went missing, sorry! Here's more general information about what haplotypes are:
www.genome.gov/genetics-glo...

Thanks to our co-authors Prof Pete Kille from @cardiffuni.bsky.social and Michael Gerardo (Dŵr Cymru Welsh Water, now at Natural Resources Wales), volunteers who assisted with field sampling and in the lab, the Cardiff Bio HPC team, and Dŵr Cymru Welsh Water and NERC GW4+ for contributing funding.

We didn’t find any new mitochondrial haplotypes (see here or here for an explanation what they are, and what they tell us about human population history) but improved our understanding of the geographic distribution resolution of the known otter haplotypes in Wales.

Mitochondrial haplotypes are clusters of inherited genetic variation in mitochondrial DNA, passed down via the maternal line. These haplotypes are particularly useful for tracing ancestry and understanding evolutionary history.

We were able to characterise the whole mitochondrial genomes (mitogenome) of the otters who left these spraints behind, as well as the fungal 🍄 and bacterial 🦠 diversity.
Our method seemed to work better in spring 🌤️ than winter ❄️, and for fresh (<24 hours) samples, but we need more data to be sure.

In our paper, we use a modern genetic technique called ‘metagenomic shotgun sequencing’ (if interested in this technique you can read more here: shorturl.at/fgROi) to characterise fungal 🍄 and bacterial 🦠 diversity of the spraint.

The paper was led by former PhD student (now Dr!) Sarah du Plessis @sduplessis.bsky.social, together with former Masters (now PhD) student Jenny Smith, supervised by myself and Liz Chadwick.

Ever found an otter🦦 spraint 💩 (faeces) along a river and wondered what information is locked in there? 🔒 Otters are still extremely elusive in Wales, so we wanted to test out a non-invasive survey method. Sequencing DNA 🧬 from spraint samples works well!

Otter ignores humans as it hunts on Mudeford Quay The otter was filmed trotting past humans at Mudeford Quay as it hunted for its breakfast.

Nice to see Eurasian #otters increasing in coastal areas of the UK, as part of their ongoing Britain-wide recovery.
We're currently studying coastal otters particularly. More on that in due course... 🦦

We are happy to be featured in this article on the revival of otters in Britain, including the link to our paper on 'effective population size’. Our research suggests that optimism about recovery should be tempered with caution - low genetic diversity may limit future population resilience.
