Not from the EU and looking to come to Sweden to do reseach? There is a grant for that! Applications taken through December 2025. www.vr.se/english/appl...

Are there other sources of N fixation? Are trees accessing N from deep mineral soil or bedrock? How will changing climate and wildfire regimes affect these other N sources and N accumulation rates??

Stefan Hupperts 🌲🍄 @stefhupperts.bsky.social · Aug 4

But known inputs fell far short of accumulation rates - especially in deciduous and mixed-dominance forests after stand-replacing fires, where 65-94% of the N was unexplained by known N inputs!

Stefan Hupperts 🌲🍄 @stefhupperts.bsky.social · Aug 4

We estimated nitrogen accumulation rates in boreal forests across the biome, and compared accumulation rates to known N inputs from N deposition and biological N fixation. If inputs matched accumulation rates, then we would have a balanced N budget.

New paper out in @jappliedecology.bsky.social ! We studied carry-over effects of nitrogen fertilization in Swedish production forests. 🌲🧪🌍

Graphical abstract of a scientific paper showing drawings of a helicopter fertilizing a forest, a harvester cutting down a tree and a tree stump next to a pine sapling with ectomycorrhizal fungi on its roots. In a 2 panel figure data on the organic layer carbon stock in fertilized and unfertilized forests is shown. In the left panel right after clearcutting, where there is a larger carbon stock in the previously fertilized clearcuts. In the right panel 4-13 years after clearcutting, when there is no longer a significant difference in soil organic layer carbon stocks.

New paper alert. We compared foliar fungal communities in native and introduced populations for a pine species (Spoiler alert: fewer pathogens in exotic populations). Shout out to an excellent international network of collaborators. 👇👇👇

The 2023 wildfire season was unlike anything Canada had seen before. What drove such extreme fire activity, and what can we learn for the future? A new CJFR collection explores these questions through expert perspectives and key research ▶️ ow.ly/2QFL50UY6ti

Check the add below for an exciting PhD opportunity! FYI, Sweden is a great place for PhD studies (full workers rights!) and less chaotic than some other places at the moment.

Curious how forest microclimate and soil microbes drive carbon cycling in a changing climate? 🌡️🌳🍄We're offering a 4-year PhD position at @mycopat.bsky.social, SLU-Uppsala. A cool new project in collaboration with @linegreis.bsky.social Apply now or help spread the word!

Every expt is humbling—I learn how much I don’t know about forests. This latest expt was no exception. In response to 13 yrs of N addition, we measured fungal mass (dead/alive), chitin conc, root tannin conc, and potential genetic capacity of EcM fungi. No trt effects detected!

Well...not really! We didn't detect any changes in soil fungal necromass and none of the potential drivers that we measured were affected either. Check out the details here: besjournals.onlinelibrary.wiley.com/doi/full/10....
