What are dendrometers and why do we need a global dendrometer network? 💥Our first GDN paper is out! We document how it all started with a meeting in Norway, and outline some of the great potential that lies in creating a global community. Read: doi.org/10.1093/tree... Join: globaldendro.org

Early defoliation, leaf browning and wilting and shedding of green leaves in Switzerland (Jura) and Southern Germany (Black Forest) - beech but also cherry and maple affected - heat and drought stress - and no rain forecasted for the next weeks. This is not unexpected - this is climate change!

Warm, wet springs may raise tree death risk, not just drought. French forest data indicate favorable early growth can leave some trees, especially tall ones, more vulnerable when later dry conditions arrive. doi.org/hb9nzf

Why Europe's trees are dying

In Europe, trees are increasingly dying prematurely. A new study by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) on French forests now shows that it is not only drought but also unusually warm or wet springs that increase the risk—even ideal growing conditions can prove fatal later on.

🌳How close are tropical forests to their photosynthetic limit? Our new paper highlights the vulnerability of these ecosystems to further warming and the importance of accurately representing canopy temperature. www.pnas.org/doi/10.1073/... @wslresearch.bsky.social

Why Europe’s trees are dying

Deviations from the usual climate are causing trees to die prematurely. Even favourable growing conditions can have a negative impact.

🌦️🌳 Why are more trees dying in European forests? Extreme summer droughts are definitely part of the story, but our new paper shows that tree mortality is shaped by climate variability across seasons, not by single extreme events alone. www.nature.com/articles/s41...

🎉 Excited to share two major milestones of this week! 📢 At #EGU25, I presented our work showing that climate change is reshaping seasonal patterns, it’s not just hotter summers that matter! 📝 At the same time, our new open-access paper in #JAMES @agu.org came out! 🧵👇

How does photosynthesis respond to changing temperatures? In the paper led by Pascal Schneider, we show that the thermal acclimation of photosynthesis can be modelled without making assumptions about plant functional types - ready for adoption in ESMs agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Global Photosynthesis Acclimates to Rising Temperatures Through Predictable Changes in Photosynthetic Capacities, Enzyme Kinetics, and Stomatal Sensitivity

Thermal acclimation of C3 ${\mathrm{C}}_{3}$ photosynthesis is predictable across species and climates using optimality theory and fundamental biochemistry Combined acclimation of photosynthetic ...
