85,000 metagenomes reveal Earth’s hidden microbiome network: 40 habitat clusters found to be shaped by hosts and environment. “Generalist” microbes bridge ecosystems, moving genes (including antibiotic resistance) across the planet 🌏🧪🌐🦠 #ComplexSystems www.cell.com/cell/fulltex...

“Scientists should stop trying to be neutral and instead embrace their values,”says a group of top climate scientists, including @katharinehayhoe.com. The neutrality myth is harming the reputation of science right when we need it most.” #ClimateCrisis Science isn’t neutral. It’s science.

“If a single animal can have several different genomes at once, which one is the blueprint? This may not even be the right question to ask...” Intriguing jumping-off point for a superb piece on why our favourite metaphors fail to capture biology; @elisecutts.bsky.social in @pioneerwork.bsky.social 🧪

🧵 🚨 Our new paper is out today in @frontiersin.bsky.social #Ecology and #Evolution. 🎉 🥳 🙌 For decades, many textbooks & papers have claimed that group or multilevel selection lacks empirical evidence. We decided to test that claim. Here’s what we found 👇 doi.org/10.3389/fevo...

Okay, you guys wanted some fun tea on Richard Dawkins? Here you go: one reason he may have gotten super duper angry about me talking about misogyny in atheism skepchick.org/2026/02/epst...

Very nice to take part of this nice workshop of @roto-rub.bsky.social in Germany next month.

In a few days Ill be 35 years old. I have reviewed 300 articles. Is that time well invested? No idea 🙃 (I havent added yet the edited articles to Web of Science. Those are 21, for 5 journals).

Comparing indigenous People’s cosmovision and teachings with the products and commerce strategy of well-known charlatans is a very enraging way of racism. Very creative racism.

A little less than a year ago the Chilean Academy of Sciences selected 20 researchers younger than 40 yo for their Frontier Science Program. That includes me and other 19 brilliant colleagues from all areas of knowledge: from Math to dentistry. Is such a privilege to belong to!

I try to review, each year, about 5 papers per article published, more or less with this same approach, but also as an Editor I know how difficult is to get reviewers so I try to review a bit more.

🚨 New Paper out 🔔 It was a blast to write this down. From my personal experience with Global North resesrchers, I conclude: they still dont get it! #science #OpenAccess #PeerCommunityJournal peercommunityjournal.org/articles/10....

Please join us at #ICOM2026 in Cairns, Australia, this summer. @anthomycota.bsky.social and me are organising a special session on mycorrhizae and biogeochemical cycles at the International Conference on Mycorrhiza (Session 23, icom2026.org). Abstract submission is open until February 28, 2026.

In our @isme-microbes.bsky.social Journal Paper “Functional Team Selection” with Nancy Johnson, we compare up to 6 holobiont definitions. Aside of that, I wonder if in 2026 people is as skeptic of holobionts as they were 10 or 15 years ago. #Holobiont #Holobionts doi.org/10.1093/isme...

I left Colombia many years ago due to right-wing paramilitar violence that killed my dad. When I go back Im always somewhat scared. It is heartbreaking to see the same going on in the US. In 4K and streamed to the world. Hope such nightmare is over soon.

With my retired PhD advisor, Roberto Godoy, we wrote this little article in homage to Nicolás Pacheco, now retired park Ranger, who has contributed A LOT to the knowledge of Chilean Flora & Fauna, for more than 50 years. Im privileged to call Nico a friend.

Muchas gracias al capítulo América Latina de @esalatamcarib.bsky.social #EcologicalSocietyOfAmerica por esta amable invitación junto a la gran @adricorrales.bsky.social de @spun.earth Siempre un gusto hablar de micorrizas. Y mejor: en español! www.youtube.com/live/2Fjs6ht...

Good to know this. Time to change slides!

Dear friends. As said before, this is the most important article I have written. For 10 years I have been compiling empirical evidence of multilevel selection in the field and the lab. Here we summarize it with fantastic co-authors (all from zoology). Release day: 10 February.

Our #ICOM2024 workshop inspired this fantastic article by @mycorrhizanne.bsky.social from @balachaudhary.bsky.social lab. I wonder what our @icom2026.bsky.social workshop on Analyzing cooperation/adaptation models (also cochaired with Nancy Johnson) will inspire. Join us with J. Hoeksema & J. Bever

Elisabeth A. Lloyd & Michael J. Wade, represent, in my view, how you should work in biology: A philosopher of science who deeply changed what we understand as adaptation & unit of selection + a quant. geneticist like no other: Mike showed empirically Wright’s phase III of shifting balance theory.

🌱 NEW at #ICOM2026! For the first time, we’re hosting an Early Career Researcher Symposium 🧫✨ 📅 12 July 2026 | 📍 Cairns 🎤 Talks, panels, networking & awards 📝 Abstracts now open for students & ECRs (≤7 yrs post-degree) 👉 icom2026.org/ecr/ #Mycorrhiza #ICOM2026 @mycorrhizaims.bsky.social

No doubt this is the most important paper I have written: “Abundant empirical evidence of multilevel selection revealed by a bibliometric review”. Since Wade 1976, PNAS, we found 280 papers showing natural selection acting at the same time at two levels. www.frontiersin.org/journals/eco...

A first for me. Bastian Matte just sussecfully defended his BSc thesis at U. Chile, and his co-director was Javiera Rubio, previously supervised by me as well. Bastian had the highest grade, congrats! Very proud!

Check out our new paper, Multilevel selection informs context-dependent mycorrhizal functioning! This is my very first first-authored publication, and I worked w some incredible folks to make it happen: @meafkhami.bsky.social @balachaudhary.bsky.social and Nancy Johnson! doi.org/10.3389/frmb...

Just got accepted a VERY important paper: Marín C, Clark AB, Philson CS, Eldakar OT, Wade MJ. 2026. Abundant empirical evidence of multilevel selection revealed by a bibliometric review. Frontiers Ecol Evol. Since Wade 1976 PNAS, we found 280 papers of multilevel sel. evidence. #evolution #life

The last peer-reviewed article by Dawkins seems to be from 2004. He is a celebrity (he even charges for dinner with him, lol), not an active Evolutionary biologist. Thus how is even possible his opinion represents the field? Furthermore, when there are MANY active Evol. Biol studying this topic.
