🍁 Heat and drought are reshaping forests. @charlottegrossiord.bsky.social of WSL and EPFL is studying how forests and their ecosystem services are affected. EPFL has now awarded her a permanent associate professorship, congratulations🎉! www.wsl.ch/en/news/wsl-... #forestecol #forest #heat #drought

Excited to share our new paper on leaf scorching. 🔥Early leaf browning during heat and drought is often interpreted as premature leaf senescence - but it may reflect rapid heat damage. Separating these processes is essential. www.nature.com/articles/s41... @wslresearch.bsky.social

🌳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

Join our exciting line-up of speakers – submit your abstract for the 48th New Phytologist Symposium: Forest interactions! Deadline: 20 May 📅 13–16 October 2026 📍 Leysin, Switzerland www.newphytologist.org/events/48-nps #PlantScience

🌲🌳 PhD opportunity: Forest Vulnerability to Hotter Droughts Interested in forest ecosystems, climate extremes & tree stress resilience? 🎓 Dual PhD (KIT 🇩🇪 + Melbourne 🇦🇺) 🔬 Plant Ecophysiology Lab, Garmisch-Partenkirchen 🇩🇪 🌍 +1-year research stay 🇦🇺 👉 Apply here: t1p.de/g39co

🌱 New ReCLEAN publication 🙌 @wslresearch.bsky.social and EPFL colleagues show how drought and warming threaten nitrogen stability in grasslands, especially under intensive management. Thanks to @vallicrosah.bsky.social and @charlottegrossiord.bsky.social ! 🔬💡 ▶️ Publication here: lnkd.in/dByaM6nx

Even trees can get serious sunburn. A new study by a WSL-EPFL team shows how #heat and #drought affect #trees and how they sustain damage when the two are combined. This helps us understand how they will react to a changing climate: www.wsl.ch/en/news/when...

🌿🌳Our new paper, led by the brillant @alyssakullberg.bsky.social, shows that trees acclimate to warming by preserving thermoregulation. Yet, with hot droughts, higher thermotolerance cannot compensate when hydraulic stress prevents leaf cooling. www.pnas.org/doi/10.1073/... @wslresearch.bsky.social

New Paper out in New Phytologist 🌸How does flower color affect heat stress? Darker flowers absorb more radiation but compensate by cooling more through transpiration and having higher thermal tolerance. nph.onlinelibrary.wiley.com/doi/10.1111/... @wslresearch.bsky.social

It turns out that drought and warming enhance the risk of nitrogen losses in intensively managed grasslands. Extensively managed ones, on the other hand, stay strong and stable! 😮‍💨Check our new publication rdcu.be/e88Cm @charlottegrossiord.bsky.social @pierremariotte.bsky.social

🌲🌡️How do forests stay cool despite #heatwaves? Charlotte Grossiord (WSL/EPFL) receives an ERC #grant of just under 2 million Swiss francs to research how European #forests cope with “atmospheric drought” and which tree species are especially resistant to heat and #drought. www.wsl.ch/en/news/how-...

It's time to apply for the New Phytologist #TansleyMedal for excellence in #PlantScience. Open to early career researchers with 3 to 5 years experience post-PhD. Applications close on 1 November. Don't miss out! www.newphytologist.org/grants-award... #ecrchat #phdchat

🌳🔥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...

onlinelibrary.wiley.com/doi/10.1111/... 🌿How you measure heat tolerance matters! We tested 3 species under different methods & durations to find their thermal limits. @a-gthy.bsky.social @kateplantphys.bsky.social @philippschuler.bsky.social

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... @charlottegrossiord.bsky.social @wslresearch.bsky.social

🌿🔥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....
