New #microsky#AMR Perspective paper with @penamiller.bsky.social rdcu.be/fqBJo ANTIBIOTIC RESISTANCE (IE MIC) AND TOLERANCE ARE NOT BACTERIAL TRAITS! Please read on if you want an explanation for this provocative claim.

🎉 Félicitations aux professeures 𝗦𝗮𝗿𝗮 𝗠𝗶𝘁𝗿𝗶 @saramitri.bsky.social @dmf-unil.bsky.social et 𝗧𝗮𝗻𝗷𝗮 𝗦𝗰𝗵𝘄𝗮𝗻𝗱𝗲𝗿 au Département d’écologie et évolution @fbm-unil.bsky.social @unil.bsky.social qui reçoivent chacune un ERC Advanced Grant @erc.europa.eu 👉 www.unil.ch/news/fr/1781...

Eye-opening work by @olimeacock.bsky.social (former postdoc, now PI in Sheffield). He presents an exact mapping from steady-state consumer-resource to generalized Lotka-Volterra models, revealing that cross-feeding can lead to competition for other limiting resources. Feedback pls!

¿Cómo explicar ese calorcito que se siente al morder un jalapeño? ¿O ese picor sabroso del jengibre? Aquí les comparto mi ensayo más reciente, que explora estas y otras preguntas sobre (casi) todo lo que pica, duele y acalora. 🌶️ 🥵 www.revistadelauniversidad.mx/articles/dc9...

Excited to share this new paper from the lab: academic.oup.com/ismej/articl...! See thread below

Really excited to share that one part of my PhD research is now publicly accessible on preprint servers! Here is a thread explaining our (@kokkonut.bsky.social and I) work on ageing and stochastic damage/failure accumulation, available as a preprint at www.biorxiv.org/content/10.6...

Delighted to see this out in its final form! doi.org/10.1093/isme... We established a discussion group focussed on the history of community ecology and how it informs our understanding of microbiota. This review distils those discussions to provide a guide for microbiologists entering the field

New paper with the brilliant @ewanflintham.bsky.social How fast does recombination suppression evolve among sex chromosomes? We show that even weak sexual antagonism (so hard to detect) makes this fast, often via inversions fixing on X/Z depending on mating system: doi.org/10.1093/evle...

Check out our pre-print led by the fantastic Massimo Amicone, collaborating with the Bollenbach lab! tinyurl.com/4h9p8mfb We build a simple intuition on how ecological interactions affect resistance evolution by expanding evolutionary rescue theory and testing it with two large sets of experiments

1(9 Great preprint from @wcratcliff.bsky.social @elibbyscience.bsky.social on obligate multicellularity and collective adaptation in snowflake yeast. Thought-provoking results! But I think the paper also highlights a deeper conceptual issue in the #multicellularity field. Let me explain:

I am genuinely humbled by the kind words from the first readers of my book! The 📗 is fully #openaccess, made possible by the generosity of libraries worldwide and @mitpress.bsky.social's D2O program: direct.mit.edu/books/oa-mon... Please help spread the word! #booksky #philsci #philsky #histsci

🚨 New preprint from the lab! 🚨 We show that multireplicon plasmids are true AMR "jack-of-all-trades": Widespread, highly mobile, broad host-range, and packed with resistance genes. Far from random, they form co-evolving associations driven & 𝘮𝘢𝘪𝘯𝘵𝘢𝘪𝘯𝘦𝘥 by IS elements. See Nacho's thread below!👇👇

The first preprint on chemostats from our lab! What a ride it's been with Eric Ulrich doi.org/10.64898/202... Congratulations on what was a challenging project that taught us so much about cross-feeding, chemostat theory and how minimal media are impossible to keep minimal ;) Enjoy the read!

Excited to share our discovery of a new programmable RNA-guided DNA-targeting system hiding inside bacteriophages that predates CRISPR. We call it VIPR (Viral Interference Programmable Repeat), and it uses an entirely new logic to find its targets. Thread + link below.

"Tell me who your friends are, and I’ll tell you who you are." It turns out, microbes follow the same rule! Very proud to share our lab's new paper in @natmicrobiol.nature.com showing that bacteria don't just respond to their environment, they respond to each other. www.nature.com/articles/s41...

Fascinating short history, including how "Isaac Newton’s famous Waste Book is a rare example of a physical continuity between the two cultures of notetaking: humanist and scientific." www.asimov.press/p/lab-notebo...

Check out our newest preprint! 📝 We find that adaptation on coevolutionary fitness landscapes is highly repeatable, but landscape-specific, and intergenomic epistasis creates coevolutionary fitness load for interacting species due to frequent fitness trade-offs 🏋️

Finally! Here is our perspective on why cooperation maximizes diversity and how it promotes additional coexistence mechanisms that do not occur under competition journals.uchicago.edu/doi/abs/10.1... This is a hard topic with strong opinions... Thanks @asn-amnat.bsky.social for publishing it! 🧵👇

This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up. Grateful (and slightly humbled) to be part of this. Thanks Alberto! www.cell.com/cell/fulltex...

Final version of our last paper is out! www.nature.com/articles/s41...

For the second preprint, we collaborated with Travis Wiles to understand microbiome transmission and its role in community assembly using zebrafish. We found that dispersal dynamics can readily move gut colonization and assembly from a stochastic to fairly predictable www.biorxiv.org/content/10.6...

New preprint on the limits of detecting higher-order interactions in microbial communities. www.biorxiv.org/content/10.6... We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.

With @saramitri.bsky.social, @sonjalehtinen.bsky.social and L. Lehmann we’ve launched the UNIL Center for Theory in Ecology and Evolution @unil.bsky.social🇨🇭 To kick things off, we’re offering short visiting fellowships for theorists in ecology & evolution. Apply & pls RP 😀 tinyurl.com/2wem36zz

What a joy to finally share the cover of The Organism–Environment Pairing (@mitpress.bsky.social)! The 📗 will be out on May 12 📆! I look forward to the conversations it sparks among scientists, philosophers & historians! mitpress.mit.edu/978026205282... #evosky #histsci #philsci #philsky #booksky 🌱🐋

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating). A brief 🧵 (carried over from the old place)

A new preprint with Matthew Schmitt, @kiseokmicro.bsky.social and Vincenzo Vitelli makes a huge step forward in learning functional groups of components in complex biological systems. It's dimension reduction that speaks to biological function. www.biorxiv.org/content/10.6...

Many organisms, including humans, reshape their environments in ways that influence the conditions faced by future generations. We ask whether this can favour biological variation with @irisprigent.bsky.social in our new paper. Thanks to @dee-unil.bsky.social @snsf.ch www.pnas.org/doi/full/10....

Yet another awesome single-phage paper from Ido Golding's lab #phagesky www.biorxiv.org/content/10.6...

The Epstein files document what many women researchers have long experienced but rarely seen laid bare so starkly: exclusion operating behind closed doors, shaping who gets funded, invited, mentored, and taken seriously. How many of these networks, norms, and gatekeepers remain in place?

📣Next week, we restart our online series with Theo Gibbs (NYU) @theogibbs.bsky.social, who will present: ⭐Do higher-order interactions promote coexistence in diverse ecological communities?⭐ Free and open! Zoom link: iite.info/seminar/ Global time checker: www.timeanddate.com/worldclock/f...
