Data for Ecological Applications publication "Developing spatially explicit critical loads for herbaceous species across the U.S. using convex hulls"

Summary: This data shows the convex hulls for open canopy, closed canopy, and all 198 species analyzed in the journal article "Developing spatially explicit critical loads for herbaceous species across the U.S. using convex hulls" in Ecological Applications. Details of the methods are in the publication. Description: Once unzipped, this folder has a summary metadata file, and two subfolders : (1) "Richness Convex Hulls" (where the convex hulls for open and closed canopy communities are located) and (2) "Species Convex Hulls" (where the convex hulls for the 198 species are located. Inside each folder .tiff files, with bands for total distance to the convex hull (<i>Distance</i>), as well as individual distances for the 5 dimensions of pH (<i>pH</i>), precipitation (<i>Precipitation</i>), temperature (<i>Temperature</i>), nitrogen deposition (<i>Nitrogen</i>), and sulfur deposition (<i>Sulfur</i>). Note that for open and closed canopy convex hulls, sulfur was not included in the original analysis (Simkin et al. 2016) and thus are not included in the convex hulls. The units for all distances are in standard deviations (unitless, based on Mahalanobis distance).
