Large differences in photorespiration and its temperature response among temperate trees https://www.biorxiv.org/content/10.1101/2025.11.22.689893v1

Photosynthesis rate at thermal optima measured in situ during two time periods in a forest site in the Central Western Ghats region show distinct dry and wet period differences. - Hilltop deciduous trees: Max out photosynthesis in the wet season, conserve water in dry spells—just as expected! - Valley evergreens: Keep photosynthesis steady during wet and dry periods. - evergreens on hill slopes: Surprisingly ramp up photosynthesis during the dry period - hinting at a taste for warmth! Our findings show that coexisting tropical trees have different heat sensitivities.

Some trees thrive in heat. Our #WesternGhats #Tropical #forest #India study shows evergreen trees 🌳🌳 on hill slopes increase #photosynthesis in the dry, hot season, not the wet - indicating heat preference 🌡️🌡️

Big thanks to SVS for support, and to SWIFT Balachandra Hegde & IDSG College for organizing. Excited that some students are now part of our photorespiration field campaign! 🌱🔬 @bobmuscarella.bsky.social

Had a fantastic four-day workshop with masters & doctoral students from across India! Trained them on photosynthesis basics, heat sensitivity, and hands-on leaf trait measurements as part of the @svs-plant-geog.bsky.social -funded field campaign #Photosynthesis #ScienceWorkshop #SVS #FieldCampaign
