Functional trait variations of the invasive plant Alternanthera Philoxeroides and the native plant Ludwigia peploides under nitrogen addition.

ABSTRACT: Quantifying the variation and coordination patterns of plant functional traits across different organs under environmental changes is crucial for understanding plant invasion and adaptation mechanisms. This study employed a space-for-time substitution experiment to compare the differential responses of root and leaf functional traits and their coordination in the invasive plant Alternanthera philoxeroides and the native plant Ludwigia peploides to nitrogen addition during different invasion degree. The results showed that: (1) nitrogen addition promoted the growth of both species, with A. philoxeroides exhibited greater biomass sensitivity. Compared to the positive effects of nitrogen fertilization, nitrogen addition facilitated A. philoxeroides in displacing L. peploides in communities wi
