This dataset includes tree eco-physiological traits characterising ranges of functioning of various components of trees. Specifically the dataset includes measurements of thermal limits of functioning of photosystem II, hydraulic safety margin, turgor loss point, CO2 assimilation versus temperature curves, leaf morphological traits for nine representative species measured during two seasons: post-monsoon and summer.

The overall purpose of the measurements from this project is to determine eco-physiological limits of functioning of tropical trees in Western Ghats India and to relate them to continuously measured temperature and water status of tropical forest trees at a representative site (Sirsi).

Provenance & quality

The trait data were measured during targeted campaigns in 2020 and 2021 at a forest fragment close to Sirsi. Measurement methodologies:

1) Thermal traits: a) CO2 assimilation temperature relationship, derived from leaf A-T (CO2 assimilation versus temperature) curves measured using LICOR 6400 and b) Temperature limits of Photosystem II functioning derived from fluorescence measurement of leaf disks heated in water bath.

2) Hydraulic traits - a) Stress (negative pressure) at which 50% of conductivity is lost based on vulnerability curves and b) Turgor loss point measured using PV curves.
