"Recently developed environment- and taxon-specific trait databases are a strong foundation for studies of #protist functional diversity, but efforts remain fragmented... a unified trait database for #protists is timely, achievable, and would catalyze transformative research on their #biodiversity, #ecology and #evolution."

"Maybe you already know how your immune system works, but you’d like someone to sum it all up in a way that helps you articulate the details when your friends and relatives bash you for protecting yourself.

So, where did this idea come from—it’s good to get sick?

It has a history.

Let’s start with a basic question: Where exactly did this idea come from that you have to train your immune system?"

🤩 Thrilled to share the first paper of my PhD project on #protist sexual cycles! 🔄🦠🤍

➡️ Are sexual cycles widespread among protist ?😲

➡️ Is there a hidden sexuality for those we can't cultivate ?🤫

New #ISEPpapers! Spatio-temporal changes of small #protist and free-living bacterial communities in a temperate dimictic lake: insights from #metabarcoding and machine learning https://academic.oup.com/femsec/advance-article/doi/10.1093/femsec/fiae104/7718122 #protists #bacteria #microbes

"While marine ecosystems have been extensively studied, there is a notable research gap in understanding eukaryotic microbial communities in temperate lakes."

`To date there is evidence of Eukaryotes using the pathway, suggesting it may be more widespread than previously thought:

Hordeum vulgare, barley uses the Entner–Duodoroff pathway.

Phaeodactylum tricornutum diatom model species presents functional phosphogluconate dehydratase and dehoxyphosphogluconate aldolase genes in its genome`

Who are giant viruses infecting in the ocean?

In a collaborative paper with the Vardi lab, we were able to link many giant virus lineages to protist hosts using #SingleCell #RNASeq. One #protist host (leucocryptos) made up less than 1% of the community, but we could still identify a cryptic viral lineage infecting it, leading to population collapse.
