New paper by Cristina Claver (@azti.bsky.social), published in @icesmarine.bsky.social JMS.
We combine #eDNA and acoustic-trawl data in a Bayesian joint model to estimate biomass of the European anchovy in the Bay of Biscay.
From the potential of eDNA to operational use

DNA in sediments tells a longer story!
New research shows sedimentary #eDNA can persist up to 132 days & be up to 1800x more concentrated than in water.

We map 3D distributions of 12 US West Coast fish species using only eDNA. By combining qPCR and metabarcoding, we turn molecules into abundance maps—revealing biodiversity hotspots and a path to continental-scale monitoring. #eDNA #ecology

Launching the @ednacollab.bsky.social DIYNAFLUOR Microgrant 2025!
For this round of microgrants, we are offering materials and support for low-cost DIY fluorometers called DIYNAFLUOR, an “affordable DIY plug-and-play nucleic acid fluorometer” that can be used for eDNA quantification. Pls share!
🚨Paper published!
Our manuscript on the differential decay rate of eDNA, erRNA and emRNA of Dolphin🐬 #eDNA is out! Is this the fastest turnaround for a manuscript ever? It certainly is for me.

Fully agree!
Working on some spatial questions with regard to #eDNA and wanted to pose a quick poll to the community, what’s the minimum eDNA dispersion scale in marine environment? Is it 100s of m, km, 10s of km, 100s of km?
My #DIYNAFLUOR presentation slides from the recent #seDNA2025 conference are now available for download.
Check them out if you want a quick overview of where and how the DIYNAFLUOR could be used to QC Nanopore library preps in low-resource settings! 🧪🧬🦕

New paper alert! 🚨- My final PhD chapter is finally out!
What happens to different eDNA components in water? 🌊💧
We tested particle size (small vs. large) and DNA molecule length (86 vs. 387 bp) in recirculating streams—and what we found might surprise you! 🧵👇

The US has such an abundant #wildlife and mesmerizing #nature. It’s a buzz killer for spontaneity that you have to pay and reserve every time you visit but maybe that’s what kept this diversity from disappearing (?).

Looking forward. See you in France 😁!
Anyone I know in this community will be joining the #AquaEcomics eDNA conference? Looking forward to present some quantitative #eDNA models!
I don’t think it’s a ‘small’ segment! It’s quite a large segment and by far the most buying power.
Can I please be added!
I’d like to be added please!
📄NEW PAPER exploring #eDNA quantification methods! For #qPCR / #ddPCR end users aiming to enhance sensitivity & precision in detecting low eDNA quantities – a common challenge in #MarineEcology surveys. Bonus: An alternative framework for LoD & LoQ.

I simply say if you go and swim in the ocean I can tell that you had been swimming 😅. People freak out a bit but then they relax when I say we only track animals
This is sooo cool!
Join the starter packs for faster rebuild of the network
Join the conversation on Marine Ecology here. Topics on monitoring, assessment, protection, conservation, restoration and management

Could I please be part of this starter pack as well 🙏
We have an open postdoc position in the Quantitative Ecosystem Dynamics lab at UC Berkeley: forms.gle/Nx1EHYiCv3yR...
in the areas of ecohydrology, land-atmosphere interactions, and global change ecology.
Please spread the word!
Can I ask to be part of this list please?
I would appreciate if I can get listed here!
It’s all thanks to the starter packs. They were really a game changer to connect the communities back together.
Can I ask to be on this lisas well?
Is the course focused on marine invertebrates?
We have figured out a way to quantify eDNA metabarcoding data just like trawls do for estimating 🐟 abundance. It's not the easiest paper to digest but I will be submitting an R package for automating the model, then it should be plug&play. Anyone interested to collab?
