Dåligt medium att förmedla mina tankar. Dessutom har jag väldigt ont om tid nu så här vid terminsstart.

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.

Forests with higher tree species richness show greater photosynthesis by capturing more sunlight, highlighting the essential role of biodiversity in enhancing carbon uptake and supporting the global c...

Not quite.

Micael Jonsson @micaeljonsson.bsky.social · Apr 4

Actually, not at all similar, as the new study follows how specific plots develop over time, not how the average plot develops (in terms of C storage).
