Reduced phenological differences under nitrogen enrichment facilitate invasion by a late-growing plant

This dataset supports the findings of our manuscript, "Reduced phenological differences under nitrogen enrichment facilitate invasion by a late-growing plant," accepted for publication in New Phytologist. The data were collected from three field experiments conducted in a salt marsh ecosystem at the Yangtze River Estuary, China. These experiments were designed to investigate how nitrogen (N) enrichment affects the phenology, competitive dynamics, and invasion success of a late-growing plant species. The dataset is organized into three primary files, corresponding to the main figures in the manuscript.
