Dataset Information

Site ID: US-PR0

Site Name: Island of Puerto Rico

Variables: Root data

Date Range: Aug. 16, 1962 - Aug. 1, 2019

Description: 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 Word document that describes metadata including the methods, the data sources and publications used in the synthesis, and information about the content of included CSV data files. Separate KMZ and csv files are attached with the collection locations.

QA/QC: None

QA/QC Method: Data was collected from search engines Google Scholar, Web of Science, and Scopus. We looked at all papers returned when searching for the key words: "root", "below ground", "plant", and "Puerto Rico". FRED (Fine Root Ecology Database Version 2) and ORNL DAAC (Oak Ridge National Laboratory Distributed Active Archive Center) were used to compare Puerto Rico's data with other tropical/global studies. Fine roots were defined as all roots less than or equal to 2 mm in diameter. Root:shoot ratio was collected using whole tree sampling. Puerto Rico root:shoot ratio was compared with global metanalyses we used the formula from the methods of Cairns et al. (1997) and Mokany et al. (2006). All statistical analyses were performed in R studio. We used ANOVA to compare root:shoot ratio as well as N and P among species. Further methods are detailed in the word document included in the attached zip file.
