Schematic depicting the distribution of the tree species studied in the Western Ghats, India. Rectangles on the left indicate the relative change in irradiance level, water availability, tree density, and soil depth from hilltops to valley areas. Codes for the species are as follows: Terminalia paniculata (TP), Terminalia chebula (TC), Careya arborea (CA), Psydrax dicoccos (PD), Tetrapilus dioicus (TD), Memecylon umbellatum (MU), Symplocos racemosa var. racemosa (SR), Hopea ponga var. ponga (HP), Knema attenuata (KA), Garcinia cambogioides var. cambogioides (GC), and Garcinia gummi-gutta (GG).

We studied 11 trees spp. across hilltop–slope–valley #thermal gradients (summer peaks: 46.1°C, 40.1°C, 31.8°C) measuring photosynthetic temperature responses and #photosystemII (PSII) T5 (5% impairment) at peak summer. 2/3
