Responses of plant diversity to precipitation change are strongest at local spatial scales and in drylands

Log response ratios of species richness (LRR S) and effective number of species SPie (LRR_SPie) at the plot, turnover and site scale. Given are covariates included in the analysis (MAP = mean annual precipitation, PET = potential evapotranspiration, delta.P = magnitude of precipitation manipulation) and study characteristics (latitude = latitude of the experiment, longitude = longitude of the experiment, study = name of the study, site = name of the site, SiteBlock = combination of site and block, replicate = replicate number, treatment.direction = direction of the precipitation manipulation, grouping.x = combination of variables, treatment.duration.y = treatment duration in years, size.local = plot size at the local scale, size.gamma = plot size at the site scale , N.replicates = number of replicates per experimental treatment). <br>
