Perfect! Thank you!
#protistsonsky Can anybody help? I am looking for a pdf of "XXV. On the Mycetozoa" by de Bary, A. (1860). Annals and Magazine of Natural History, 5(28), 233–243.
Key scientific events this week for the Oslo Mycology Group #OMG.
1- Maria Feiring brilliantly defended her Master thesis on the ecology and diversity of Myxomycete on boreal Forest soil and dead Wood.

Det er valg! Lurer du på hvordan partiene står i forhold til hverandre? 📊 Her er en hovedkomponentanalyse (PCA) basert på NRKs valgomat.
Fargene viser ideologisk blokktilhørighet, og linjene kobler partiene i et minimum spenntre – korteste vei som forbinder alle uten å lage løkker. #valg2025 #nrk
Another version of our DNA metabarcoding course coming to an end. Thanks to the students and teachers @krabberod.bsky.social @ramalok.bsky.social @kbohmann.bsky.social @daniel-vaulot.bsky.social @micahdunthorn.bsky.social
@krabberod.bsky.social presenting the Ribosomal Operon Database (ROD) at our ongoing DNA metabarcoding course
onlinelibrary.wiley.com/doi/10.1111/...
- The web interface now provides access to the ROD database that contains full-length eukaryotic ribosomal operons developed by @krabberod.bsky.social
I am very happy that ROD (The Ribosomal Operon Database) is now included in the outstanding PR2 web interface, enhancing its accessibility and utility. I hope to make some updates to ROD in the near future. with @drhyfe.bsky.social
Announcing the new release of the PR2 database, version 5.1.

Very big thanks to all the contributors: @fonamental.bsky.social @ambonacolta.bsky.social @krabberod.bsky.social and more...
A few highlights:
New paper by our group, mutation accumulation experiment in heat-stressed Arabidopsis!

Let's kick of the New Year like an acantharian with a little #protistsonsky fireworks magic. Happy New Year 2025! 🦑
Last Sunday of 2024 - Hoping for better year beginning this week!!!
"Ants solving a geometric problem and it's amazing."
This is a great example of 'emergent phenomenon':
- None of the ants understand the problem they're solving.
- None of them can see the whole shape.
- A series of small decisions or rules add up to something with a new layer of complexity.
An image of a radiolarian from the Carribean Sea off of Puerto Rico, likely from the genus Eucecryphalus. Looks like a little glass hat.
An image of a radiolarian from the Atlantic Ocean off of Bermuda, likely from the genus Eucecryphalus. Looks like a little glass hat.
One of my favorite radiolarians. I call it a "little hat", but I guess it is probably Eucecryphalus sp. Here are two examples from Bermuda (Atlantic) and Puerto Rico (Caribbean). Exquisite little #protistsonsky. I love seeing these forms in different regions of the Oceans. #protistaday #marinelife
International Society of Protistologists is funding two symposia at the 16th International Congress of Protistology in Seoul, South Korea. Proposals are due 30 January 2025

The rhizarian testate amoeba Euglypha rotunda eats its co-cultured bacteria, but it will also chow down on GFP E. coli. One day I'll use these vids to measure digestion rates. @thealgaeman.bsky.social another answer to what they eat! #protistaday #protistsonsky
Sometimes you need to take your little shelled amoebas out for a walk. Rhizarian testate amoeba euglypha rotunda #protistsonsky #protistaday
New preprint led by Ruben Gonzalez-Miguens for a new coi database that should be useful to annotate metabarcoding datasets with protists.
www.biorxiv.org/content/10.1...
Happy to be part of this effort led by Rubén González-Miguéns: A Novel Taxonomic Database for eukaryotic Mitochondrial Cytochrome Oxidase subunit I Gene (eKOI) https://www.biorxiv.org/content/10.1101/2024.12.05.626972v1 eKOI will be integrated into @pr2-database.bsky.social 🙌 #protistsonsky
🧬🦠 Exciting new resource for #protists lovers! The eKOI database to expand the power of COI metabarcoding with a focus on #protistsonsky & integrated in @pr2-database.bsky.social Lead by Rubén with @beaplab.bsky.social @fonamental.bsky.social @daniel-vaulot.bsky.social

Palpitomonas: the movie. I like this blurry little video because it shows the cryptistid Palpitomonas with its two absurdly long flagella beating with two different patterns. I imagine it as a pianist playing different parts with each hand. #protistaday #protistsonsky
An SEM image of a testate amoebozoan that makes its shell from debris in the environment.
An SEM image of a testate amoebozoan that makes its shell from food particles--mostly diatom tests in this case!
The rhizarian testate amoeba that I shared yesterday makes its shell out of intricate, self-constructed glass scales. Other testate amoebozoans in the same environment make their shells out of debris (left) or food (right). These are interesting examples of convergence! #protistsonsky #protistaday
Today's #protistaday is a scan through a multinucleated Acantharian cell from here in the Gulf of Maine. All of the larger Acantharians I've looked at have multiple nuclei like this... need to take a look at/stain the teeny "baby" ones to see how these structures develop! #marinelife #protistsonsky
SEM image of a rhizarian testate amoeba (euglyphid) showing its glass scales.
Not a fish or a dragon scale, but a single cell of a #protistsonsky. This rhizarian testate amoeba creates perfect tiny glass scales to build it's shell. From a peat bog. #protistaday.
