THIS DATA PACKAGE ACCOMPANIES: The Diversity of Animals Identified as Keystone Species, I. Shukla, K.M. Gaynor, B. Worm, C.T Darimont This data package contains the original dataset as well as R code used to generate figures and analysis. ############################################# CONTENTS ######################################### Shukla et al. README.txt -- This file, including a description of variables. Diversity_of_keystones_suppList.csv -- A data file that includes the full list of author-identified keystone species Diversity_of_keystones_index.csv -- A data file of each of the keystone traits indexed for a k-means clustering analysis Keystone_diversity_code.R -- supplementary code of the descriptive statisics, k-means clustering analysis, and vizualization for keystone trait diversity ################################################################################################# VARIABLE NAMES AND DESCRIPTIONS FILE: Diversity of Keystones_suppList.csv Latin name: Indicates species scientific name Common name: Species common name Order: Species Taxonomic Order Title: Title of the publication from which the species was sourced Authors: Condensed citation of the lead author(s) Year: Year that the article was published Journal: Journal that the article was published in.
