Very happy to write this Species spotlight for #Nature Ecol. Evol. about our beloved Alerce.
Its been a huge privilige to work with this #AMF conifer for many years now.
Thx to the E-i-C for the invite & Mateo Barrenengoa for the pic.

I teach a guest class in a BSc Evolution class, about Units of Selection. My first question to the students is about their definition of evolution. It almost always involves alleles.
A phenotype-based def. of Evolution must include several other factors that affect trait expres. & popul. composition

A big thanks to @cmarin.bsky.social who talked about plant holobionts and gave a great insight into the fascinating world of mycorrhizal fungi in our lecture series yesterday. 🍄 Thank you also to everyone who joined the talk and the discussion afterwards!

I have been inspired by David Sloan Wilson writing since I was 18 years old (2009). Recently spend a week with him, his wife Anne, & Nancy Johnson in Arizona.
David told me Im a pretty good writer. I value that more than all the awards I have received. David is way ahead!

organized by @thegsbi.bsky.social
next year in Victoria, Canada. Particularly nice to be in such good company!
Ill be talking about Soil biodiversity networking from the global south; mycorrhizal natural selection; and more!

Open letter: A global call to strengthen national soil biodiversity action through coordination and harmonization

Other genes (hundreds of them even) in the genome influence a gene’s effect on phenotype.

Even other genes in other individuals also have effects on a focal individual gene effects and fitness.

There is tones of evidence on this. Why we keep teaching 1-1 or few-1 genotype-phenotype relationships?

Why for some people is so easy to (rightly so) dismiss things like Mother Trees (wood wide web) but they’ll hold equally unsustained stories like Selfish genes?

Bought these four books. One by my co-author Mike Wade. Two by my friend/mentor (in a way), David Sloan Wilson, and The Dialectical Biologisr by Levins & Lewontin.

Aftonbladet's interview with Greta Thunberg is now available in English - it raises many serious questions, not least about the Swedish govt. effectively abandoning its citizens to torture because it doesn't agree with their politics. A thundering disgrace.

Check out preprintwatch.com to see the degree of disruption of your research.
Im glad Kuhn framework is fully used here.
My recent ISME J paper with Nancy Collins Johnson was deemed as ‘Model revolution’.
Indeed.
