Maybe there’s no better β€œnatural #eDNA sampler” than a sponge. But here we show why #jellyfish maybe also deserve some consideration:

Can we circumvent the cumbersome filtration of #edna from seawater to detect rare taxa? Yes! Passively deploying simple cost-effective cotton membranes can, with trade-offs of course. @sednasociety.bsky.social doi.org/10.7717/peer...

And their ecological impacts are much more widespread and diverse than is often communicated. Here, I try to put the record straight. I do so while describing a recent paper of ours that introduces a new categorisation of 19 impacts types that invasive species have across ecological hierarchies.

Proud of this new publication demonstrating #eDNA as a useful accessory to invasive species management in practice. In this case, we observed eDNA declines coinciding with community-led apple snail removal from an Austin, Texas pond. www.reabic.net/journals/mbi...

πŸŽ‡New paper alert
GENETIC POLLUTION-caused by human-driven hybridization-is more widespread and dangerous than you think.

With modern DNA tools, we can act BUT policy must catch up fast!

Are offshore wind farms the next safe spaces for sharks and rays? - Oceanographic New eDNA evidence has confirmed the presence of active shark and rays around Dutch offshore wind farms, posing an exciting new question.

🦈 Offshore wind farms may offer safe zones for sharks & rays.🌍 Dutch researchers found eDNA of 5 species, incl. basking sharks, in turbine areas.πŸ§ͺ Bans on bottom trawling could help marine life rebound.🌐

After 4 year as a subject editor for @oikosjournal.bsky.social I am stepping away to focus more on my students and teaching. It’s been fun and educational! I’d definitely recommend it.
If anyone qualified in the #eDNA sphere is looking to be an editor, let me know and I can pass along your info.
