Comparative evolution of photosynthetic light response curves: Approaches and pitfalls in phylogenetic modeling of a function-valued trait

The dataset includes directly measured values (reference and analysis values for carbon dioxide and water vapor, atmospheric pressure and flow rate, exterior and interior light levels, and cuvette temperature), as well as calculated values (leaf temperature, transpiration rate, vapor pressure deficit, stomatal conductance, net photosynthetic assimilation, and intercellular carbon dioxide concentration). Note that four species with narrow leaves did not fill the chamber cuvette (see article for adjustment method), and 3% of data points have partially missing data values due to the instrument entering auto-zero cycle.

The dataset was used to conduct function-valued trait (FVT) modeling of the evolution of light curves with phylogenetic comparative methods. The dataset could be used as part of meta-analysis or synthesis requiring light response curve data, with appropriate considerations of data limitations.
