Environmental Fluctuations Promote Host Reward Strategies That Maintain Partner Diversity in Multispecies Mutualisms | The American Naturalist: Vol 205, No 2 Abstract In multispecies mutualisms, hosts might be expected to reward only the highest-quality partner in order to maximize benefits and prevent the proliferation of cheaters. In a fluctuating enviro...

Was literally just panicking about this over the weekend 💩

I love the way they move

😂 maybe four stuck together

It was identified as a nectosome elsewhere 😌

Anybody know what this marine invert is? It's from an epipelagic plankton net tow in the middle of the Atlantic #invertID

My friends in the Life of Retaria group decided to make a podcast! In the first episode, they interview @fabnot.bsky.social about his journey as a scientist. I loved the first episode, hope you do too! @juliemeilland.bsky.social @sandinmm.bsky.social et al.

That must be where the amoeba got its artistic inspiration 😀

testate amoebae are my fave 🤩

Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462...
Led by @n-llopis-m.bsky.social, and thanks to all co-authors, I'm very happy to finally see it out!

Pause for a minute to appreciate the valiant Program Officers still at NSF, who are doing their utmost to preserve what they can. They’re in the stinking rotting belly of the beast, laboring on our behalf.

❤️❤️❤️❤️ to them

It's an incredibly depressing time to be an American scientist

Expansion microscopy micrograph of the choanoflagellate Choanoeca flexa, vaguely evocative of a cactus. Red = tubulin, green = actin, blue = DNA

Same with yellow = lipids (BODIPY)

A dream come true: the first expansion microscopy images of C. flexa 🤩 Generated by Mylan & Uzuki who learned from the best (@hiralshah.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social). We will learn so much from these!

WOW 😍

Was able to take the image, thanks to you and the samples you sent me! 😄
