Supplementary Materials of "Elementary mathematics helps to shed light on the transpiration budget under water stress"

This directory contains the Jupyter notebook used to do complete analysis from our paper "Elementary mathematics sheds light on the transpiration budget under water stress" submitted to the Ecohydrology Journal at the Special Issues "ECOHYDROLOGY OF INLAND AND COASTAL WATERS in honor of Ignacio Rodriguez-Iturbe". These materials are referenced in the main text and supplemental text of the publication. The purpose of this repository is to facilitate replication of our analysis by any interested parties. Specifically, this directory contains ten files: From 0 to 5, Jupyter Notebook prepared and used for the analysis (please execute the notebooks in numerical sequence). "Table_S1.xlsx" Data From: Kröber, W., H. Heklau, and H. Bruelheide. 2015. “Leaf Morphology of 40 Evergreen and Deciduous Broadleaved Subtropical Tree Species and Relationships to Functional Ecophysiological Traits.” Plant Biology 17 (2): 373–83. https://doi.org/10.1111/plb.12250. "Richards_VG.csv" contains Van Genuchten Parameters for various soils. "The_Rosetta_Stone_of_the_Darcy_Buckingham_law.pdf" addresses the challenge of converting water flux units between Darcy-like soil and plant descriptions, where hydrologists use "head" units (meters) and plant physiologists use pressure potential (MPa). The aim is to clarify and perform the necessary unit conversions, with detailed explanations available in the relevant section on this webpage.本目录包含用于完成我们提交至《生态水文学期刊》（Ecohydrology Journal）“内陆与近岸水域生态水文学”——纪念伊格纳西奥·罗德里格斯-伊图尔贝（Ignacio Rodriguez-Iturbe）特刊的论文《初等数学揭示水分胁迫下的蒸腾预算》完整分析流程的Jupyter笔记本。 这些材料在该发表论文的正文与补充文本中均有引用。本代码仓库的设立目的在于便于所有感兴趣的研究人员复现我们的分析工作。 具体而言，本目录包含10个文件： 1. 编号0至5的Jupyter笔记本：为本次分析编写并使用，请按数字顺序依次运行这些Notebook。 2. "Table_S1.xlsx"：数据源自Kröber, W.、H. Heklau与H. Bruelheide于2015年发表的论文《40种常绿与落叶阔叶亚热带树种的叶片形态及其与功能生态生理性状的关联》，刊载于*Plant Biology* 17(2): 373–383，DOI: 10.1111/plb.12250。 3. "Richards_VG.csv"：包含多种土壤的Van Genuchten参数（Van Genuchten Parameters）。 4. "The_Rosetta_Stone_of_the_Darcy_Buckingham_law.pdf"：针对水通量单位在达西类土壤描述与植物生理描述之间的转换难题展开探讨——水文学家通常使用“水头”单位（米），而植物生理学家则采用压力势单位（MPa）。本文档旨在厘清并完成必要的单位转换，相关详细说明可参见本网页的对应章节。
