New publication! 🎉 🧬 eDNA signals continue changing post-capture We tracked DNA persistence across collection materials and showed: ⏰ time, 🌡️ temp, and substrate drive detectability A step towards more standardised and field-ready airborne eDNA! bit.ly/435t2Ez #eDNA

Non-destructive genomics from museum collections?🫙🧬 A new MER study by @erinhahn.bsky.social & colleagues show the promises and limitations of recovering historical biodiversity signals from specimen preservation media. #HistoricalDNA #Metabarcoding @wileyecology.bsky.social doi.org/10.1111/1755...

If there's DNA hiding in the vaults, we'll find it! 🧬 📣 New paper out, affectionately called BUCKET-Seq, we explored liquid media as a non-destructive source of specimen DNA. DNA is recoverable from specimen media but we caution that it stems from mixed sources. bit.ly/3P7hEVk #Museomics #eDNA

Registration + abstract submissions are now open for the 2027 Southern eDNA Society Conference in Canberra! 🎉 ednaconference.com.au Theme: Scaling eDNA: From Method to Mainstream Join researchers, practitioners, industry & community partners shaping the future of eDNA. #eDNA #SeDNAS2027

So proud to see our PhD student Kate’s first chapter in print! She shows that clonal geckos are far from genetically uniform. An elegant demonstration that sex, past or ongoing, underpins the persistence of asexual vertebrate lineages. Read it here: doi.org/10.1111/mec....

🚀 Preprint alert! 🚀 #AirDNA – game changer or hot air? Fresh from last year’s @sednasociety.bsky.social Airborne #eDNA workshop, we’ve distilled the latest research, key challenges, and a roadmap to turn this emerging tool into real-world solutions. Check it out! 👇 🔗 doi.org/10.32942/X2S...

New life mantra. Attack every challenge with the enthusiasm of a 14 yo at her first rock concert and the commitment of a 50 yo punk rocker playing his 30 yo classics. Then take a nap because everything hurts. #GreenDay in Sydney kicked ass last night!! #SaviorsTour #hairspray #dookie #concertmum

#SeDNA2025 closing panel, MCd by Chris Meyer Michael Marnane, @manpreetkdhami.bsky.social, @digleeson.bsky.social, & Olly Berry Aus/NZ don't yet have a "national eDNA strategy" but the real game changer for our region is that we have a great collaborative culture (e.g., @sednasociety.bsky.social!)

Wrapping up the final science session at #SeDNA2025, Chris Meyer from the Smithsonian shares the US's National Aquatic #eDNA Strategy Goals: Co-ordinate ➡️ Build ➡️ Apply "We need to be more efficient and effective with the resources we have"
