Role of top-down-rehydration in drought tolerance of mangroves

该项目旨在了解红树林地上部对大气水分(水蒸气、雾、雨、露水)的吸收和储存在红树林存活中的作用。在红树林中，高盐度限制了根系的水分吸收，特别是在炎热、干燥的条件下。这项研究将促进对干旱和盐分耐性的理解。该项目的成果将包括确定限制干旱生存的环境条件，以及增强干旱生存的功能植物特征。这些结果对于解释红树林在干旱情况下死亡的机制至关重要，并将有助于开发基于过程的模型，以便更好地预测红树林对气候变化的反应。

This project aims to understand the role of absorption and storage of atmospheric water (vapour, mist, rain, dew) by shoots in survival of mangroves where high soil salinity limits root water uptake, particularly during hot, dry conditions. This research will advance understanding of drought and salinity tolerance. The project outcomes will include identification of environmental conditions that limit drought survival and functional plant traits that enhance drought survival. These outcomes are fundamental to interpreting mechanisms underlying mangrove dieback under drought and will benefit the development of process-based models for better prediction of mangrove responses to climate change.
