We did field work last week in the large area affected by the Västmanland wildfire that happened 12 years ago. Lots of deciduous regeneration and a thick Polytrichum moss layer!

Nature research paper: Rising atmospheric CO2 reduces nitrogen availability in boreal forests go.nature.com/3Op1Hca
Rising atmospheric CO2 reduces nitrogen availability in boreal forests - Nature
Nitrogen isotope tree-ring chronologies show that rising atmospheric CO2 has reduced nitrogen availability in boreal forests in Sweden, suggesting that elevated atmospheric CO2 is causing oligotrophication in boreal forests.

I am really excited to share our new paper, published today in Nature. We show that rising atmospheric CO2 is linked to decling nutrient availability in boreal forest, with implications for the future carbon sink. Kudos to lead author @kelleyrbassett.bsky.social. www.nature.com/articles/s41...

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!

In their 2021 study, @j-karst.bsky.social et al found that 13 years of N addition in boreal aspen forests was linked with more "high biomass" ectomycorrhizas. Does that translate to more fungal necromass in the soil?...
