A cool highlight was that bacteria from feet, where fungi are particularly diverse, tended to be more broadly antifungal than those from other body sites! #microevo

70% of known antibiotic resistance genes (ARGs) circulate on food products, with 40% of these ARGs on mobile elements (mostly plasmids), mostly belonging to two major pathobionts (Acinetobacter and Staph spp). Important summary stats on the resistome! #MicroEvo #AMR

Excellent piece on misconceptions of speciation 🤦

1. Species can be clearly defined
2. Speciation is good
3 Species-poor lineages are ancestral/primitive
4 Speciation is strictly tree-like
5 microevo is unimportant
6 Trait differences must contribute to speciation

My entire team wrote an opinion paper about Common misconceptions of speciation research. Each section is written by 1-2 team members. The bulk of the writing happened during two writing retreats. It was a lot of fun and I am very happy with the result. academic.oup.com/evolinnean/a...

Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy - Nature Communications
It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core genomes across 50 major bacte...

I would make the elipses overlapping.
Some microevo and macroevo processes are a bit overlapping.
Also ecology timescale is same as rapid microevo timescale and they feedback each other.
This is more complex to explain bit to me more accurate and satisfying
