Data and R Code in"Community functional traits shift under long-term nitrogen addition: Roles of intraspecific trait variability and species turnover"

This dataset contains raw and processed data, along with R scripts used to generate Figures 1–6 in the manuscript titled "Community functional traits shift under long-term nitrogen addition: Roles of intraspecific trait variability and species turnover". The study explores the trait-based responses of plants to nitrogen addition, using linear regression models, structural equation modeling, and Sum of squares decomposition analysis. Each figure is associated with a dataset (.xlsx) and corresponding R script(s) for full reproducibility.
