Shameful decision

We just released #anvio v9, "eunice" 🎉 This version represents over 2,000 changes in the codebase since v8, increasing the total number of programs in the anvi'o ecosystem to 176. Read the release notes: github.com/merenlab/anv... Visit our up-to-date web page: anvio.org

Closely related microbes tend to live in similar communities across Earth’s environments. We call this pattern community conservatism - extending established ecological patterns to the microbial world. 🧬🌍 #MicrobialEcology #Evolution Read the full article here: doi.org/10.1038/s415...

I'm thrilled to share that this work has just been published: onlinelibrary.wiley.com/doi/10.1111/... We compared to contrasting observatories: 🌴 ☀️ Equatorial Atlantic (EAMO, 6°S), one of the first in low-latitudes 🍂 🌸 A well-studied temperate site (BBMO, 41°N) in the Mediterranean Sea 🧵⬇️

Now published in Nature Biotechnology: go.nature.com/44P7nSm If you missed it, the TL;DR is in my April thread below

Microbial rhodopsins are everywhere in the surface ocean, but were assumed to play a role mainly when nutrients are scarce. Our new study reveals unexpected rhodopsin dynamics tightly linked to phytoplankton blooms.

"By 2030, our goal is for microbial metrics to stand alongside those of charismatic megafauna in every major habitat monitoring and restoration plan, signalling a profound shift in how biodiversity is measured, valued and protected" www.nature.com/articles/s41... @noc.ac.uk

Chapter 3 of my thesis is now available as a preprint in @biorxiv-ecology.bsky.social We compared 3+ years of coastal microbial time-series from an equatorial site (EAMO, 6°S) and a temperate site (BBMO, 41°N). Our work reinforces the need for observatories across latitudes to track ocean change.

Attention long read metagenomists! This feels like an important read. Misassemblies stitching together bacteria, archaea, and euks all into the same contigs, yikes! Reports of circularisation isn’t robust. There’s a lot in here to ponder.
