📣 A huge thank you to our first two keynote speakers, Dr. Marín (@cmarin.bsky.social) and Dr. Jansson, for starting #GSB2026 off strong!

Topics ranged from soil microbes as climate solutions to complexity science as a foundation for mycorrhizal research; we could not imagine a stronger start!

Right on time for #GSB2026, soil fauna made it to the cover of Nat Eco Evo (great shot by frankashwood.bsky.social). Attendees who have questions on the journal or papers to pitch, feel free to chat to me at the conference. @thegsbi.bsky.social

Do primate brains and social insect colonies make decisions in similar ways? As shown in this @royalsocietypublishing.org paper, both share competing populations that accumulate evidence until a threshold is reached. @jordipinero.bsky.social @drmichaellevin.bsky.social @dornhaus.bsky.social

ust got accepted my 80 peer-reviewed article:
“Migration should be a personal choice, not the only one – a reflection on scientific diasporas” on Research Ideas and Outcomes.

There we discuss how to get to a functional scientific diaspora.

Out of the 12 press pieces I have seen of our @frontiersin.bsky.social
in #Ecology & #Evolution paper

“Abundant empirical evidence of multilevel selection revealed by a bibliometric review”, this one by @MSN is the best one!

Written by an IA, with human oversight.

Constanza is my third bachelor thesis student who finished her thesis with the highest grade possible and with a WoS paper published before finishing. Cherry on the cake: already with a permanent job.

Couldnt be more proud!

3 great news:
- We have started our SOCBIO-MAP project fund. by European Space Agency.
- Tomorrow a very nice paper in collab/funded by SPUN will appear in Biod. Conserv. We now know about the mycorrhizas of one of the oldest trees in 🌍
- Ill give a talk in Harvard on Wednesday

Clonal-aggregative multicellularity tuned by salinity in a choanoflagellate - Nature The choanoflagellate Choanoeca flexa forms motile and contractile cell monolayers purely clonally, purely aggregatively or through a combination of both processes depending on environmental conditions.

A study in Nature shows that the single-celled form of a tiny, aquatic organism can turn into a multicellular version by three different routes. The discovery adds insight to the possible origins of multicellular life, suggesting a previously unrecognized degree of flexibility. 🧪

Organisms are not machines.

This should be mainstream thought in ecology, Evolution, genetics, physiology, and so on.

Sadly it seems like we are not there yet.

The fact this is not mainstream thought in the biological sciences shows the bad situation we still are in!

February, 2026 – Mycorrhizal picks (2025) By: César Marín On this new section of our blog, in my capacity of Editor of about seven journals, I am posting what I call: “César Marín’s mycorrhizal picks”, where I list scient…

I estimate over 1000 Mycorrhizal Research papers are published each year. It is impossible to keep up! However I try. For @southmycorrhiza please find a list of my Mycorrhizal picks for 2025! Tons of exciting research in ecology, agriculture, Evol., etc!

Evolution Is Not Just About Survival of the Fittest Individual In the 1990s, an agricultural scientist named William Muir set out to breed better egg-laying hens. His approach seemed obvious: pick the most productive

Is not often you find good science blogs. This one is as it reflects pretty well our @frontiersin.bsky.social Ecol Evol paper: “Abundant empirical evidence of multilevel selection revealed by a bibliometric review”, from discussing Muir’s poultry work to yeasts!

To understand mycorrhizas and mycorrhizal functioning I have been reaching out to colleagues working with very different systems.

One of the most toxic features in academia is over-specialization. Otherwise wonderful thinkers become zealots.

Really enjoyed watching this paper unfold. The idea that selection operates at multiple levels is fascinating, controversial and difficult to test. But not untestable nor untested. César and colleagues show this well!
