#dinoflagellates — Public Fediverse posts

Tiny but full of stories. 🌊🔬 Scientists from around the world meet at MARUM – Center for Marine Environmental Sciences, University of Bremen for #DINO13 to discuss modern and fossil #dinoflagellates.

🚨 ALERT: Scientists discover microscopic ocean drama! 🤯🔬 After 60 years of intense observation, it turns out #diatoms and #dinoflagellates have been battling for biomass supremacy in the North Atlantic. 🌊 Clearly, Mother Nature is more compelling than any Netflix series. 🎬🍿

Light-regulated #chloroplast morphodynamics in a single-celled dinoflagellate https://www.pnas.org/doi/10.1073/pnas.2411725121

"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."

A decade of dinoflagellate #genomics illuminating an enigmatic eukaryote cell https://bmcgenomics.biomedcentral.com/articles/10.1186/s12864-024-10847-5

"#Dinoflagellates are a remarkable group of #protists, not only for their association with harmful #AlgalBlooms and #CoralReefs but also for their numerous characteristics deviating from the rules of eukaryotic biology. #Genome research on dinoflagellates has lagged due to their immense genome sizes in most species (~ 1-250 Gbp)."

The source of #paleozoic (hemi-) #pelagic calcareous #mud (before the rise modern pelagic calcifiers) has been bugging me, again, recently.
I have seen arguments for calcification of #cyanobacterial filaments, calcareous #dinoflagellates, breakdown of thin-walled fossils, and I'm not negating #abiotic sources.

Does anyone have any thoughts on the topic?

"As a densely populated micro-ecosystem, the #plastisphere is made up of primary producers, predators, symbionts, and decomposers. #Diatoms are considered to be one of the earliest colonizers of plastic surfaces. Over time, as the community matures, they are replaced by other eukaryotes, such as heterotrophic #dinoflagellates."

#Dinoflagellate vertical #migration fuels an intense red tide https://www.pnas.org/doi/10.1073/pnas.2304590120

"The idea that vertical swimming gives #dinoflagellates a competitive advantage actually goes back more than half a century, but only now do we have the technology to conclusively prove it in the field"

Last night, when most sensible people were in bed, I was standing in the sea for a couple of hours watching and photographing the bioluminescent plankton at Rhossili Bay!

Bioluminescent plankton is notoriously unpredictable and can appear at any time at any tide or not appear at all.

Palynomorphs

TIL There is a concept that refers to spores of ferns and mosses, to pollen of seed plants, to dinoflagellates, and to some extinct stuff.

Oooo! New (to me) things! I think these are some dinocysts of the Polykrikos genus of dinoflagellates. If you think different, let me know! #alwayslearning

I’m still on that steep dinoflagellate cysts learning curve ! Here are some spikey fellas from my latest sample.

This is very cool. Some dinoflagellates have a resting stage as part of their lifecycle, called a dinocyst (or hypnozygote). And here’s one! A dinocyst of the genus Protoperidinium.

ahhh marine glow, just checking my dinoflagellate cultures in my lab. everytime so beautyful! #bioluminescent #dinoflagellates no cell was harmed! #science #lab

Look at what I found! My first Noctiluca scintillans aka sea sparkle! These are the dinoflagellates that bioluminescence when disturbed. Only really visible is there’s lots of them I would think. But so exciting!

Mussels everywhere, but not allowed to eat! Red tide neurotoxins accumulate in shellfish, making them too dangerous to eat. Participants warned not to eat them because they can cause Paralytic Shellfish Poisoning. #Alone #VancouverIsland #RedTide #Plankton #Dinoflagellates
