🌳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 🌡️💦

Do aquaporins play a key role in regulating leaf gas exchange—especially under unsaturation in the stomatal cavity at high VPD? We think so! Check out our opinion piece in Plant, Cell & Environment with Haoyu Diao and @arthurobuntspecht.bsky.social:

A nice variability between the seedlings of Quercus pubescens from Pfynwald/Switzerland, Barcelona/Spain, and Crete/Greece. Looking forward to test how they cope with heat stress above 40°C

Interesting summary how politics influences scientific freedom, but not sure why Switzerland is only in the top 30%-40%.

PhD student in Plant Water Relations
Extreme droughts and heatwaves are increasingly threatening forest ecosystems in Switzerland, altering water availability and leading to tree stress. The DeepDrought project aims to advance our understanding of plant reliance on deep soil water and its role in mitigating drought stress. We are seeking a highly motivated PhD candidate to assess species-specific root water uptake patterns, dendrometer derived tree water deficit, and water use efficiency across Swiss forests using a combination of field observations, stable isotope analyses, and predictive modeling. The PhD candidate will focus on assessing plant reliance on deep soil water and will work closely with a multidisciplinary team across the Swiss Federal Institute for Forest, Snow, and Landscape Research (WSL), ETH Zürich, and the Technical University of Munich (TUM). The research will contribute to refining our understanding of plant-water interactions and enhancing climate resilience strategies for Swiss forests.
You hold a master’s degree in environmental sciences, hydrology, ecology, forestry, or a related field. Experience with field data collection, particularly soil or plant water measurements, is an asset. A strong background in statistical analysis is desirable. Familiarity with stable isotope data, dendrometry, or soil hydrology is advantageous. Proficiency in programming languages such as R or Python for data analysis and modeling is required. You are highly motivated, independent, and eager to collaborate in an interdisciplinary research team. Excellent English skills are necessary, and knowledge of German or French is a plus but not essential.

🌲 🥳 Save the date: 13.09.25 Open day at the Stillberg research site to celebrate its 50th anniversary!

In 1975, WSL and SLF planted 92,000 trees in a joint project on the Stillberg in the Dischma Valley near Davos. On 13 Sep the public can visit this long term research site.

More than 90% of fossil fuel emissions occurred since my parents were born.
Over 80% since I was born.
Over 30% since my children were born.

And well over 50% since the world agreed at the Rio Earth Summit to prevent dangerous climate change. And I thought: „At last!“
