In massive #collaborative #effort, we assembled published & unpublished #fish 🐟 #eDNA 🧬 metabarcoding datasets, covering ~2000 sampling sites/>100 river systems globally. 🐟 🐠 🐡 🌐 🌍

Now results out in 2 #parallel #preprints @biorxiv-ecology.bsky.social

Every year a highlight & intense period: Our molecular ecology module! We train advanced Master students on how to apply DNA & #eDNA #metabarcoding to assess riverine #biodiversity.
Long #Day1 today as we sampled until 19:30. Motivation: 10/10. Tomorrow: to the lab! @unidue.bsky.social @sgn.one

By comparing three strategies for local bioassessments in streams using environmental DNA and RNA metabarcoding, researchers find the most effective strategy is to briefly incubate collected organisms in water then analyse the enriched eDNA.

🚀 A big thank you to all participants and instructors of our eDNA Metabarcoding course! 🙌

We explored amazing user-friendly tools like BolDigger, Aspcale, and TaxonTable, had a great intro to @nanoporetech.com data, and wrapped up with an inspiring open discussion full of ideas and projects.

Our team @unidue.bsky.social turned 🔟 today & I found myself in a spontaneous celebration event.
Really happy & grateful to work here with such a great bunch of talented & nice people - connected to our collaborators around the 🌎. Life could be worse. Weiter geht‘s. ☀️Maybe more lab work next 🔟 ?

Very good to see our @pensoft.net journal @mbmg.pensoft.net continues to receive good CiteScores and also now the first #ImpactFactor with a good value of 3.1 ☀️
While I personally don’t care much about these metrics I know they are really relevant for many institutions. Thus: very happy about this!

🙏 And just as an addition: don‘t use these primers for bulk sample metabarcoding. There others are ways better (we recommend fwhF2/fwhR2n as a good solution; further solutions like BF2/BR3 or mlCOI with dgHCO exist)

Different labs can produce vastly different results which leads to ‘eDNA doesn’t work’ - ring and proficiency testing is key. Establishing minimum standards (e.g. sequencing depth) and metadata reporting is crucial. Stringency of standards will vary by taxonomic group #UKDNAWG25
