Data from: Elevational cline in herbivore abundance driven by a monotonic increase in trophic level sensitivity to aridity

Climate DataLocation and climatic variables of each study site. Temperature and precipitation variables were estimated for 2012-2015 using the PRISM Climate Group Model, and day of year of first snowmelt was estimated using a regional regression (Petry et al. 2016).ClimData.csvClimate Data R CodeThis is the R script for analyses of the relationship between elevation and multiple climatic variables as well as the principal component analysis of these climatic variables. This R script uses the ClimData.csv data file.Aspen Canopy Surveys DataThe abundance of ants and aphids in aspen canopy surveys conducted in 2012.AspenCanopySurveys.csvAspen Canopy Surveys R CodeThis is the R script for analyses of aphid and ant abundance in aspen canopy surveys conducted in 2012. This script uses the AspenCanopySurveys.csv data file.Trophic Level Manipulations DataData describing interspecific interactions involving host plants, aphids, natural enemies, and ants in two, three, and four trophic levels treatments imposed in 2015.TrophicLevelManipulations.csvTrophic Level Manipulations R CodeThis is the R script for analyses of whether aridity mediated aphid performance directly and indirectly by altering aphid multi-trophic species interactions. This script uses the TrophicLevelManipulations.csv data file.Ant Abundance and Resource Use DataThe abundance of ants collected in pitfall traps in 2012 and 2015 as well as ant bait consumption in 2015.AntAbundanceResourceUse.csvAnt Taxonomic Composition in 2012 DataAnt taxonomic composition in pitfall traps in 2012.2012MultivariateData.csvAnt Taxonomic Composition in 2015 DataAnt taxonomic composition in pitfall traps in 2015.2015MultivariateData.csvAnt Abundance and Resource Use R CodeThis is the R script for analyses of ant abundance and taxonomic composition in pitfall traps as well as bait consumption. This script uses the AntAbundanceResourceUse.csv, 2012MultivariateData.csv, and 2015MultivariateData.csv data files.READMEThis file contains descriptions of all data files and R scripts.
