Sampling success at the @arnoldarboretum.bsky.social with @alyssakullberg.bsky.social and Thibaut. What an amazing place to work! If you have temperature thresholds data and want to join forces, let us know! You'll make us and @charlottegrossiord.bsky.social happy.

New PhD position in Plant Ecophysiology🌳 Study how atmospheric & soil drought shape tree carbon & water relations at the VPDrought experiment in Switzerland. Start Jan 2026. Apply here: m.refline.ch/273855/1759/... @wslresearch.bsky.social

🌳🔥Out now: Our review on compound droughts and forest responses - from leaf to ecosystem. Featuring a stunning 20-yr map of canopy temperatures variation across European forests. @chriswernerlab.bsky.social @simonhaber.bsky.social @vallicrosah.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Can beech and oak saplings adjust to prolonged periods of warmer temperatures🌡and soil drought? 🏜
Come find it out at my presentation at @egu.eu!
Looking forward to this experience as a first attendee!

Did you ever wonder when to use "conifer", "gymnosperm", "needleleaf", "angiosperms" and "broadleaves"? Us too so we transformed the discussion into this viewpoint. I hope you enjoy the reading as much as we enjoyed the writing! @kateplantphys.bsky.social nph.onlinelibrary.wiley.com/doi/full/10....

🌳Urban trees keep cooling - even during record-breaking heatwaves! We show that trees maintained high transpiration, defying model predictions. Tree cooling during heat may be underestimated 🌡️💦
Great study led by Christoph Bachofen @wslresearch.bsky.social doi.org/10.1016/j.uf...

Of course that‘s just some initial thoughts, and it definitly requires further reflection 😊

Great question Rosie! We first need to understand how these limits vary broadly among species/PFTs. We then also need to integrate them into stress/mortality algorithms (heat-related thresholds, thermal damage functions related to cumulative exposure) and couple it of course with drought stress

💥What we found:
Tcrit is stable and reversible
T50 & Tmax drop with longer exposure & depend on method
Recovery mainly happens before T50 - beyond that damage is irreversible.
If you want to predict forest resilience, method and duration can’t be ignored 🌿

🌿How you measure heat tolerance matters! We tested 3 species under different methods & durations to find their thermal limits.

Really great paper! It shows that while photosynthetic acclimation to warming can matter at the leaf level, it might become irrelevant at the canopy scale for total carbon uptake - simply because of reduced canopy size. Scale matters! 🌿🔥

Congrats Janisse!

My first paper is out! We investigated how #photosynthetic and #respiratory #thermal #acclimation 🌡️ and #canopy size 🌳 shape tree net #carbon uptake under prolonged warming and drought. Check it out: onlinelibrary.wiley.com/share/author...

Fantastic study using a combination of a long-term manipulative study, microCT and modelling (Sureau) led by Laura Mekarni, together with @hcochard.bsky.social

Sorry, the doi is correct but it seems that has not been activated yet. It works when you go through the PCE website first

🌿🔥How heat and VPD shape tree survival? We tested how acclimation to high temperature & VPD impacts drought mortality. While heat speeds up death via leaf area expansion, VPD acclimation slows it down by enhancing stomatal control - balancing mortality timing. doi.org/10.1111/PCE....

'What excites me is the chance to work with incredible scientists from all over the world, some of whom are just starting their scientific journey.'

Had an amazing time with the PERL group on our first night-time sledding adventure in the Swiss mountains! Great fun, lots of laughs, and unforgettable moments, speeding down the slopes under the stars. ❄️🛷✨

🌿 Join us for a workshop at our unique VPDrought field site in Switzerland on Aug 21-22, 2025! The event will feature a field site tour & presentations from experts studying VPD impacts on forests worldwide. Don’t miss the chance to connect & collaborate! www.wsl.ch/en/events-an...
