Plant root trait measurements raw data, 1962-2018, Island of Puerto Rico

This data package is a compilation of studies and raw datasets on root traits including root biomass, root nitrogen and phosphorus concentrations organized by different root diameters, species, soil depth, and forest types in Puerto Rico. The attached zip file contains a metadata document "archive metadata.docx" in Word document and PDF formats that describe the methods of data collection, the data sources and publications used in the synthesis, and information about the contents of the two CSV data files "root.shoot.ratio_PR.csv" and "Raw data.csv." Also included are a KMZ file with data collection locations and an additional CSV file with coordinates for each site of data collection organized by data author and year of publication. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: USDA Forest Service - International Institute of Tropical Forestry.本数据包为波多黎各地区根系性状相关研究与原始数据集的汇编，涵盖根系生物量、根组织氮与磷浓度，相关数据按根系径级、物种、土壤深度及森林类型进行分类整理。附件压缩包内含一份以Word文档与PDF格式保存的元数据文档「archive metadata.docx」，该文档详述了数据收集方法、本综合数据集构建所用的数据来源与已发表文献，以及两个CSV数据文件「root.shoot.ratio_PR.csv」与「Raw data.csv」的内容说明。压缩包同时包含一份记录数据采集点位的KMZ文件，以及一份额外的CSV文件，该文件按数据作者与发表年份分类整理了各数据采集站点的坐标信息。本数据集最初发布于NGEE Tropics档案库，现由ESS-DIVE进行镜像以实现长期归档存储。致谢：美国农业部林务局-热带森林国际研究所（USDA Forest Service - International Institute of Tropical Forestry）。
