The air is full of DNA — here’s what scientists are using it for Airborne genetic material can be used to paint a picture of ecosystem health, watch for invasive species and even identify humans.

Great historical narrative on the emergence of airborne #eDNA methods: www.nature.com/articles/d41... I'm happy to have contributed to the field and mentioned in this feature.

Integrating eDNA and acoustic-trawl data to provide small pelagic biomass estimates for fish stock assessment Abstract. Accurate abundance estimates of fisheries resources are essential for sustainable fisheries management. In response to the growing need for devel

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.

Fish environmental DNA is more concentrated in aquatic sediments than surface water Genetic identification of aqueous environmental DNA (eDNA) provides site occupancy inferences for rare aquatic macrofauna that are often easier to obt…

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! 🧪🧬🦕

Comparing the Fate of eDNA by Particle Sizes and Molecule Lengths in Recirculating Streams The detection of environmental DNA (eDNA) has revolutionized aquatic species monitoring, yet interpreting eDNA data remains challenging due to gaps in our understanding of eDNA ecology (i.e., origin,...

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.

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!
