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...

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 oligotrophic...

Does discharge Q drive chemistry C in intermittent streams? No. They depend more on dry-wet transitions Highly variable CQ at low Q change to consistent CQ at high Q, signalling a switch from a biogeochemistry-driven dry to flow-driven wet state agupubs.onlinelibrary.wiley.com/doi/10.1029/...

I'm so excited to share our new paper in Global Change Biology: A network of 18 wildfire chronosequences reveals key environmental drivers and knowledge gaps in the boreal nitrogen balance, with @michael-gundale.bsky.social and others. doi.org/10.1111/gcb....

We are hiring a postdoc at Umeå University in aquatic ecosystem ecology. See the link for details! www.umu.se/en/work-with... @grocherros.bsky.social

Big CONGRATS to @kacizarek.bsky.social!!! Her new paper is out in @agu.org's JGR-B! The paper has a little bit of everything -- N biogeochemistry, intermittent stream hydrology, concentration-connectivity relationships! Check it out here: agupubs.onlinelibrary.wiley.com/doi/full/10....

Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data. agupubs.onlinelibrary.wiley.com/doi/full/10....

If plankton to plants is catastrophic or not time the great tester In our group a highlight has been using long-term monitoring data to test ideas in ecology. Here we asked “does the theory of the alternative stable states in shallow lakes stand the test of time?” doi.org/10.1038/s414...

Bimodality and alternative equilibria do not help explain long-term patterns in shallow lake chlorophyll-a - Nature Communications

Shallow lakes have long been considered an example of alternative equilibria in ecological systems. Here, the authors combine empirical data and simulations to show that the relationship of shallow la...

"Abrupt transformation of west Greenland lakes following compound climate extremes associated with atmospheric rivers". This new article in PNAS by Jasmine Saros and colleague Vendy Hazuková is pretty striking www.pnas.org/doi/full/10....

My first post on bsky to announce my first solo author paper is out in @aslo.org L&O Letters. doi.org/10.1002/lol2... Thanks to lots of amazing conversations with collaborators and a call out on that other social media to gather info on lakes, rivers, streams, wetlands, etc with calcium carbonate.

We often think of rivers as linear features, but lateral dynamics are just as important and often overlooked! In our paper we present a framework for the study and management of rivers which emphasises lateral connectivity. #floodplainconnectivity #riverrestoration Link to paper shorturl.at/ri3lA

Check out our new paper in Ecology Letters! We examined how the N-fixing cyanobacteria Dolichospermum's ionome and physiology changed in response to short—and long-term adaptation to different N supplies. Take home: There is a lot more than Fe changing in diazotrophs. doi.org/10.1111/ele....

Current and Historical Resource Nitrogen Supply Affects the Eco‐Physiological Traits and the Ionome of a Diazotrophic Cyanobacterium

Yesterday's single #nacreous cloud was nice, sure, but this morning we had an explosion of them! Again, everyone in Umeå seemed to have something to say about them. We are all connected in our awe or rainbow clouds. #cloudappreciation #photography #LifeNearThePoles

I am soon recruiting two PhDs and a postdoc, to work on carbon, methane, metabolism in arctic stream networks. Glad to chat potential opportunities during #AGU24 @agu.org ! There is also soon another postdoc position on oxygen responses to peatland restoration with @ryansponseller.bsky.social ⬇️
