that their introduction to the world – first track on their first album - is "break on through" is just 🀯🀯🀯

@phylieu.bsky.social has been gushing over this album lately, too

thanks for this. I read this in my 20s on a trip through the desert, even so I probably didn't appreciate it like you did – this thread makes me want to re-read it

Are you interested in how diatoms communicate with each other? Exciting post-doc position available in my lab to study the signalling mechanisms of cell-cell communication in diatoms. Deadline 14th July. @kehelliwell.bsky.social @thembauk.bsky.social www.jobs.ac.uk/job/DNO210/p...

Looking back on last week's Molecular Life of Diatoms conference 🌊. Honored to be hosting this tight-knit, creative and collaborative community in Ghent! Topics ranged from single-cell approaches, imaging breakthroughs, new insights into photosynthesis and symbioses etc. #protistsOnSky #MLD8

Those are fully intact diatoms that are normally highly motile. Does it glue them all down so they can't move?

And it's all the same diatom species – are the diatoms dividing on the amoeba, or does it specifically collect the same diatom species? Wild.

Many amoebae incorporate diatoms in their shells, but Cylindrifflugia bacillariarum is the master. Third and fourth pics are close views of the glue that holds it all together. #ProtistsonSky #Amoebae #Peatlands

New paper on diatom phylogenomics from our lab. Ten years in the making, but it always took a backseat to student and postdoc papers.

I'm sympathetic though: all these lowly taxonomy, classification, and organismal biology problems represent extremely inconvenient truths that get in the way of high-throughput science. It's hard to know about all these things as organisms. It slows you down. Like a lot.

Worried if freshwater diatoms that can't withstand the teeniest tiniest dash of salt show up in the middle of the ocean?

Why state that taxonomic "classes" are monophyletic, even when no phylogenetic tree has ever, ever supported that? Wishing it were true?

What's your expectation for comparisons of species diversity and abundance in two genera that differ in age by 80 million years? What's your null? How about comparing two genera, when one is phylogenetically embedded within the other? 🀯

This is prevalent in the metabarcoding and metagenomics literature, where reads are classified into some ranked named group, and those names are compared. Many named groups are not monophyletic, and others names of equivalent taxonomic rank differ in age by tens of millions of years.

There tends to be a discounting of taxonomy and classification as "simple" and inconsequential exercises with no implications for the real world. The problem is that people use classifications to draw biological conclusions. Like all the time.
