@skyfaller @nancywisser I wonder how the Academy of Natural Sciences of #Philadelphia came to be the publisher of a book about #Montana’s #diatoms. Where are all the Montanan academic presses?

They oughta be ashamed that they let some east coast press publish the definitive work about their state’s diatoms, written by the curator of the Montana Diatom Collection! Is there no state pride in Big Sky Country??

When I ordered "Fishes of the Wissahickon" from Drexel, they accidentally sent me "Diatoms of Montana and Western North America: Catalog and Atlas of Species in the Montana Diatoms Collection" by Loren Bahls instead. They're sending the correct book, but they don't want me to return "Diatoms of Montana".

What should I do with "Diatoms of Montana"? It's two volumes, pretty thick. If I lived in Montana I'd probably hang on to it, but I'm not that into diatoms or Montana.

Team of #HZDR & #CNRS explains how #diatoms interact with #uranium. As algae can be the starting point for the accumulation of harmful substances in the food chain, the results help to better understand the impact of the release of uranium on natural cycles.

"These photoreceptors enable them to detect changes in the light spectrum in the water column, thereby providing information regarding their vertical position within it."

Protein shell discovery reveals how #diatoms capture CO₂ so effectively https://phys.org/news/2024-10-protein-shell-discovery-reveals-diatoms.html

"diatom pyrenoids are encased in a lattice-like protein shell... not only gives the pyrenoid its shape, but it helps create a high CO2 concentration in this compartment. This enables Rubisco to efficiently fix CO2"

"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."

Researchers investigate how freshwater diatoms stay in the light https://phys.org/news/2024-03-freshwater-diatoms-stay.html

Declines in ice cover are accompanied by light limitation responses and community change in freshwater #diatoms: Brittany Zepernick et al. https://academic.oup.com/ismej/article/18/1/wrad015/7513090

I’m super excited by this one. I think, I _think_, this is Amphitetras antediluviana, a new-to-me species of diatom from Cromer. I ADORE their cubic form 🎁 (yes more geometry!)

Can anyone shed any light on this little mystery? Too big to be the diatom Cylindrotheca closterium, my second guess is a dinoflagellate (perhaps Amphisolenia sp.?). What do you think? Any help would be greatly appreciated.

Twisty twisty! This colonial diatom Asterionellopsis glacialis is increasing in my samples. It has been known to bloom around here so it’ll be interesting to see how, when, and if that happens this year.
