The provided data contains Adobe Illustrator files (Illustrations.zip) for conceptualizing trait plasticity mechanisms, experimental setup, and plant traits. The data further holds all information on plant and environmental variables measured in the field (Data.zip) and R-scripts (Code.zip) used to analyze the establishment, survival, biomass dynamics, trait variation, effect of environmental gradients on plant trait expression of marram grass and produce the figures for the publication by Höfer et al.
