Proud moment here, I started to work on this data during my PhD in 2016 and now almost 10 years later, this paper is published.
✨ New open-access publication! ✨

This study sets a benchmark for defining reference ecosystems in Sphagnum-dominated #peatlands of Eastern Canada, analyzing 168 peatlands to describe #bryophyte habitats.

I think (hope) this marks the end of my field season!
And what a beautiful way to wrap it up, at a #peatland restored in 2023, with a lush carpet of Sphagnum mosses 🌿

Also, yes, that’s a bread knife in my hand. If you’ve ever sampled peat or moss in the field, you know it’s an essential tool 😉🔪

So permafrost peatlands burn and they release lots of CO2 through combustion - but that's just the start. Christopher Schulze shows in a new GRL study that slow recovery causes continued CO2 losses in the following decade - overall similar in magnitude to the combustion!

📢 New Peatpedia post! A brief intro to #peatland soils, peat fossils, and moss piglets. Moss piglets! Microscopic creatures wriggling in the moss. I got very distracted doing background research on them, so a future post will be dedicated entirely to moss piglets!

🛠️ Cool tool alert!

Past PhD student Sebastián Gutierrez Pacheco built a method to estimate daily water table levels from sparse data — using PERG data 🌿

Glad to see this topic at the top of CBC News - watching fires burn up the boreal year after year sucks, and it's the peatlands burning that I worry about most
Wildfires send Canada's carbon emissions soaring. And our peatlands emit even more | CBC News
A new government model to estimate peatland emissions and their impact on climate change could provide a new perspective on the problem — and spark new discussions about solutions.

If you think we're not comparing numbers and seats of courses among colleagues, you'd be wrong. Female faculty teach bigger and more lower level courses. Oh, we know. We've counted.
In a study of professors, women got 378 new work requests over 4 weeks vs 118 for men. Women spent more time on service, advising & teaching; men on research. Orgs should track who is taking extra duties & ensure they are rewarded and distributed fairly. www.forbes.com/sites/kimels...
