Short summary
Andean tropical montane forests are highly biodiverse and store carbon at levels comparable to lowland forests, yet their response to climate change remains uncertain. Using a leaf-level photosynthesis model and a transplant experiment across three elevations (14, 22 and 26 °C) in the tropical Andes, we show that intraspecific variability in key photosynthetic parameters is essential to accurately model photosynthesis and avoid underestimating montane forest carbon uptake.
