Important study showing that the conversion of old-growth to young forest results in significant carbon losses www.nature.com/articles/s41...
Global covariation of forest age transitions with the net carbon balance - Nature Ecology & Evolution
A global analysis reveals regional trends of net forest ageing but also that widespread stand-replacing disturbances, such as fire and harvest, are driving declining forest age in many areas, often ac...

Field work on the islands close to Arjeplog, northern Sweden, can sometimes be quite magical 😍

A very nice study, showing that forests with more tree species capture more sunlight and show higher levels of photosynthesis! And this pattern is global.

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 ⬇️
