Pantropical Tree Sapwood Hydraulic Properties, 1991 - 2014

This data package contains sapwood pressure-volume parameters including osmotic potential at full turgot, turgor loss point, bulk elastic modulus, and others, determined by curve fitting to raw isotherm data (paired measurements of water content and water potential). Raw data were digitized from published figures. Data are from natural tropical and subtropical forests or savannas and span rainfall gradients from deciduous dry tropical forests to everwet tropical forests, and come from the following countries: Argentina, Panama, Brazil, Costa Rica, and Madagascar. Included in the attached zip file are four CSV files. sapwood_PV_recal_headers.csv: description of variables in the two files below sapwood_PV_recal_corrected.csv: bias-corrected sapwood PV data (see Methods in the associated reference) sapwood_PV_recal_uncorrected.csv: uncorrected sapwood PV data (see Methods in the associated reference) sapwood_PV_references.csv: citation, bibliographic reference, and DOI for the published references from which data were extracted. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival本数据包收录边材压力-体积参数，涵盖完全膨压下的渗透势、膨压丧失点、体积弹性模量等指标，上述参数通过对原始等温线数据（含水量与水势的配对测量值）开展曲线拟合计算得到。 原始数据均从已发表的科研图表中数字化提取。数据集采集自天然热带、亚热带森林及稀树草原，覆盖了从落叶干旱热带森林到常绿湿润热带森林的降雨梯度，涉及阿根廷、巴拿马、巴西、哥斯达黎加及马达加斯加五个国家。 附带的压缩归档包内含四个CSV格式文件：sapwood_PV_recal_headers.csv：下述两个数据文件的变量说明文档；sapwood_PV_recal_corrected.csv：经偏差校正的边材压力-体积参数数据集（详细方法参见关联参考文献）；sapwood_PV_recal_uncorrected.csv：未经过偏差校正的边材压力-体积参数数据集（详细方法参见关联参考文献）；sapwood_PV_references.csv：数据提取所依据的已发表文献的引用信息、题录及DOI。 本数据集最初发布于NGEE热带生态系统实验归档库（NGEE Tropics Archive），现由ESS-DIVE进行镜像归档以实现长期留存。
