Top-down rehydration: role of multiple water sources in mangrove function

该项目旨在结合尖端的分析和成像技术来评估大气水源对枝-水平衡的贡献，确定与自上而下的再水合作用相关的叶片特征，并确定红树林使用的不同水源在维持光合碳同化方面的相对重要性，沿着盐度和干旱的自然梯度。枝条吸收大气水分的能力可能深刻影响红树林的多样性、生存和生产力，因为高土壤盐度限制了根系的吸水，特别是在炎热干燥的条件下。

This project aims to combine cutting-edge analytical and imaging techniques to assess contributions of atmospheric water sources to shoot-water balances, identify leaf traits associated with top-down rehydration, and determine the relative importance of different sources of water used by mangroves in maintenance of photosynthetic carbon assimilation along natural gradients in salinity and aridity. The capacity of shoots to absorb atmospheric water could profoundly affect the diversity, survival and productivity of mangroves where high soil salinity limits water uptake by roots, particularly during hot, dry conditions.
