New paper out! Arctic tundra shrubs keep records of beaver colonisation ❄️🦫🌿✏️ Our new study in Ecosphere used shrub growth rings & satellite imagery to reconstruct past beaver colonisation at the northern edge of their range in Arctic Canada. 🔗 doi.org/10.1002/ecs2... @esajournals.bsky.social

Thanks to all collaborators on this project. This manuscript was written almost entirely to the sound of "Here in the Pitch" by Jessica Pratt. Beautiful album I can strongly recommend. open.spotify.com/album/3sxWkh...

Engagement with the farming community has been a big problem. The previous administration implemented a free milk testing programme - any farm can get their milk tested for H5N1 for free! Over 36,000 dairy herds in the country, how many do you think signed up for testing? Answer - 75...

There's been one national intervention - testing cows that move from one state to another (no federal restrictions on movements within a state!). Our study shows that this has simply not been enough, and will have only prevent a small number of additional outbreaks.

Thom Rawson @thomrawson.bsky.social · 09/05/2025
Based on the movement data, we would expect a lot more herd outbreaks, in a lot more states. The vast majority of outbreaks have been in California. Is California just unlucky? No, they're simply identifying more outbreaks. Wisconsin and Florida in particular are particularly bizarre omissions.

Our modelling paper synthesises data on the movement of cattle across the country. Dairy cows get moved around A LOT. By moving infected cattle from one state to another, cows are infecting new herds in new states via shared milking equipment. We discovered this is just the tip of the iceberg...

Super thrilled to say our study "A Mathematical Model of H5N1 influenza transmission in US dairy cattle" is now live in Nature Comms. doi.org/10.1038/s41467-025-59554-z Within days of being identified, cases of H5N1 in cows were popping up all over the US, how was it spreading so quickly? 🧵

Feels like people are putting a lot of faith in the fact that pandemics are rare events, often — though not always — with multiple decades between them. Nature doesn't work on a schedule. We assume it does at our peril. www.nytimes.com/2025/03/26/h...

Federal officials cited the end of the Covid-19 pandemic in halting the research. But much of the work was focused on preventing outbreaks of other pathogens.

I've been seeing this "risk increases 5-fold this winter" stat a lot. H5N1 obviously a big threat, but this specific stat is very misleading. That is a five-fold increase compared to the summer, and based on a non-peer-reviewed model. Basically just "more flu in winter".

Responses from HICs "rooted in colonial architecture". HIC experts might parachute in for short stints, when these skill sets are just not relevant to the particular challenges. Instead need to focus on supporting and facilitating peer-to-peer expertise. 2/3
