How do we tell when plants are stressed—before our eyes can see it? Prof. Youngryel Ryu’s team has shown that even mid-resolution hyperspectral cameras can detect solar-induced chlorophyll fluorescence (SIF), a faint light emitted by plants that reveals early signs of stress.

Street trees do more than just look nice—they store carbon too! A team at SNU, led by Prof. Youngryel Ryu, has created a way to spot and measure the carbon held by each tree using a camera and LiDAR system mounted on a car. It’s a big step toward greener, smarter cities.

🌲Out today in Science! We show that thermal acclimation of stem respiration could significantly reduce future forest carbon losses under climate change. A weaker carbon-climate feedback than expected? 🔗

New Article: "Plant traits shape global spatiotemporal variations in photosynthetic efficiency" https://t.co/1zgBwxN7MT Integrating remote sensing and eco-evolutionary theory, this study explains 80–84% of photosynthetic efficiency variation across ecosystems.

🌱 Our team recently explored how plants across the globe make the most of sunlight. We found that traits like leaf lifespan and chlorophyll content—alongside climate—play key roles in shaping photosynthetic efficiency. 🌍💡

🌱Good News: Plants Are Adapting 🌍 Prof. Youngryel Ryu’s team from SNU’s Dept. of Landscape Architecture and Rural Systems Engineering has made an exciting discovery: plants from the tundra to the tropics are adjusting their canopy photosynthesis to thrive in higher

We are looking for two 3yr postdocs to join us @NUSgeog! One will work on tropical vegetation monitoring using phenocam, sap flow and eddy covariance ( https://t.co/jUnVwwqZhs). One will broadly work on modelling vegetation dynamics under climate change ( https://t.co/iDwGcKzig7).

How to produce environmentally sustainable rice? In this work, we integrated a holistic mechanistic model with a heuristic evolutionary algorithm to reduce GHGs emissions and irrigation consumption without compromising crop yield.

In this work, we found that dark respiration is highly likely the driving force behind nocturnal stomatal conductance in rice plants.
