Root responses to warming and hurricane disturbances in a wet tropical forest of Puerto Rico: R code and data

The purpose of this data was to generate a scientific article that describes the responses of tropical roots to a warming experiment and to the effect of two consecutive hurricanes in Puerto Rico (Yaffar et al. in review). This data is from 10 months of minirhizotron images taken every 2 weeks at the experimental warming Tropical Responses to Altered Climate Experiment (TRACE) plots in Puerto Rico before and after Hurricanes Irma and Maria. This project has 3 warmed plots (plot 2,4,6) and 3 control plots (plot 1,3,5) with 2 minirhizotron tubes at each plot. As part of the data, there is also root data taken from cores and in-growth cores. Additionally, there is soil nutrient concentration data, soil microclimate, total leaf area, and canopy openness taken by Reed et al. 2020, and the TRACE census. Data files are in CSV format and the R code included in this package can be used with R 3.4.4 (R Core Team and contributors worldwide). This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: This data was supported as part of the Next Generation Ecosystem Experiments-Tropics, funded by the U.S. Department of Energy, Office of Science, Office of Biological and Environmental Research.

本数据集旨在支撑一篇科学论文的撰写，该论文将阐述热带根系对增温实验的响应，以及波多黎各遭遇连续两场飓风后的影响（Yaffar等，待刊）。本数据集的数据来自波多黎各热带气候改变响应实验（TRACE, Tropical Responses to Altered Climate Experiment）增温样地为期10个月的微根窗（minirhizotron）图像采集工作，每两周拍摄一次，覆盖飓风艾尔玛（Irma）与玛丽亚（Maria）前后的时段。本项目设置3个增温样地（样地2、4、6）与3个对照样地（样地1、3、5），每个样地配备2根微根窗管。本数据集还包含从土芯与原位根生长芯（in-growth cores）采集的根系数据；此外还涵盖由Reed等2020年测定的土壤养分浓度、土壤微气候、总叶面积与冠层开度数据，以及TRACE样地普查数据。数据集文件均采用CSV格式，本数据包附带的R代码可在R 3.4.4版本（全球R核心团队与贡献者）下运行。本数据集最初发布于NGEE热带生态系统实验档案库（NGEE Tropics Archive），并已镜像至ESS-DIVE以实现长期归档。致谢：本数据得到下一代生态系统实验-热带项目（Next Generation Ecosystem Experiments-Tropics, NGEE Tropics）的支持，该项目由美国能源部科学办公室生物与环境研究办公室资助。橡树岭国家实验室由UT-Battelle为美国能源部管理（合同编号：DE-AC05-00OR22725）。此外，本研究还得到美国农业部林务局国际热带森林研究所与波多黎各大学里约皮埃德拉斯分校的支持。TRACE项目的资助来自美国农业部林务局、美国能源部科学办公室以及美国国家科学基金会（资助编号：DE-SC0012000、DE-SC-0011806、DE-SC0018942、89243018S-SC-000014、DEB-1754713）。
