2/2 but today, early in the morning, before the sea got rough, with lots of help from our friends Mikey and Adi from the IOLR sea-going team, we found them! The lights were already off, but some cumaceans, amphipods, isopods, and fish larvae were still swimming inside 🌊🦐💡

1/2 Last thursday, we placed three light traps in the rocky subtidal ca 400 offshore @iolr-il.bsky.social, to collect demersal #plankton for heavy metal analysis. Yesterday we lost the GPS signal and couldn't find them...

Gelatinous organisms are good candidates for parasite research as they are mostly trasparent 🪼. Although bigger ones (some >10 kg!) pose a humongous challenge. 👆 this video of a trematode metacercaria was taken from the tissue of the Red Sea ctenophore Eurhamphaea vexilligera (fig i,j) #biodiversity

New preprint out! Are jellyfish🪼 parasite 🪱 highways🚦? For years, we collected parasitic worms from gelatinous hosts in five seas and mapped their global records. Turns out gelatinous zooplankton have an important role in the life cycle of parasites, and vice versa: www.biorxiv.org/content/10.6...

🦞🥬🥕🐸 An #invasive crayfish that clones itself, survives droughts, eats almost anything - even cannibalize its own juveniles! In fragile semi-arid habitats, this flexibility may be exactly what makes an invader so hard to stop. Check out our new #NeoBiota paper: neobiota.pensoft.net/article/1830...

🤔👾 What if the first sign of an invader is not something we see, but something we sequence? Check out our new paper, proposing MODAS (Molecularly Detected Alien Species) as a warning flag for #eDNA detections 👻🧬🚩 👉 tinyurl.com/49vm3cfu #eDNA-LEV @skatsanevakis.bsky.social @iolr-il.bsky.social

Indeed! The number and shape of the rhopalial lappets, and the shape of the manubrium (mouth), are consistent with an early-stage ephyra of Aurelia

If you ever seen the seafloor after a seaweed bloom, it can get dark, and the mud might stink from decaying macroalgae. There are a lot of processes involved, mostly microbial. Nutrients have a surprising (to me) role in all of it. 🧪🌊 Link: pubs.acs.org/doi/abs/10.1...

@zoopel.bsky.social just presented our MODAS concept at the #GuardIAS Conference: a database flag for alien species detected solely through molecular tools. By integrating these “invisible invaders” into IAS systems, we can prioritise validation, boost early warning, and modernise biosecurity. #eDNA

2/2 Today, we went out on a small boat to check whether the shark might have followed a plankton patch although this is not a productive season. The codend was full of chaetognaths and blue pontellid copepods ⛵🏹🪱🦐💙 Some more to come after the analysis 🔬🧬 @iolr-il.bsky.social

🦈🐳🌊 A giant visitor in Haifa! 1/2 For the second time in two weeks, a whale shark was spotted along the southeastern Mediterranean — a rare and exciting event! Whale sharks feed on zooplankton, especially sergestid shrimps, chaetognaths (arrow worms), and calanoid copepods 🦐🏹🪱 @iolr-il.bsky.social
