Photosynthetic heat tolerance is shaped by trait coordination, acclimation, and evolutionary history

This dataset contains physiological, morphological, and environmental data used to investigate the mechanistic drivers of heat tolerance in woody plants across California. The study assessed 109 species across 14 sites, spanning a 1,000 km latitudinal gradient. We aimed to identify the primary drivers of photosynthetic heat tolerance across California’s diverse ecosystems, considering the role of evolutionary history, acclimation to local temperatures, and functional traits. We also evaluated whether heat tolerance is linked more closely to "carbon economic" traits that govern long-term growth strategies and resource investment or to "energy balance" traits that mediate leaf temperature.本数据集涵盖生理学、形态学与环境学相关数据，用于探究加州境内木本植物耐热性的机制性驱动因素。本研究对横跨1000公里纬度梯度的14个样地中的109个物种开展了测定。本研究旨在明确加州多样生态系统中光合耐热性的主要驱动因素，同时考量进化历史、对本地温度的驯化适应以及功能性状的作用。此外，本研究还评估了：耐热性是更紧密关联于调控长期生长策略与资源投入的「碳经济性状」，还是更密切关联于调控叶片温度的「能量平衡性状」。
