Data and R Code for Trait Variation and Environmental Drivers in<i>"</i><b><i>Community functional traits shift under long-term nitrogen addition: Roles of intraspecific trait variability and species turnover</i></b><i>"</i>

This dataset contains raw and processed data, along with R scripts used to generate Figures 1–6 in the manuscript titled <i>"</i><b><i>Community functional traits shift under long-term nitrogen addition: Roles of intraspecific trait variability and species turnover</i></b><i>"</i>. 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 (<code>.xlsx</code>) and corresponding R script(s) for full reproducibility.
