摘要： Background and Aims Enhanced atmospheric nitrogen (N) deposition can lead to substantial variation of aboveground biomass (AGB) in grassland communities. While most studies have been conducted at community and functional group levels in response to short-term N addition, few studies have focused on patterns and controls of AGB in response to varying duration of N addition at a species level. Methods We compared effects of short- (6 years) and long-term (16 years) N addition on AGB and traits associated with shoot density, seed, and tissue elements of the common perennial forb rhizomatous species Potentilla bifurca L. in a temperate steppe of Inner Mongolia. Results Short-term and long-term N addition had comparable effects on AGB of P. bifurca, whereas the canopy- seed-related traits differed substantially in response to the N-addition regimes. Effects of short-term N addition on AGB was mostly indirect by modifying the basal space of its early-stage competing species in the community. Effects of long-term N addition on AGB were substantially intensified due to the legacy effect of N enrichment, with the positive effects on belowground sucker-emerging, crown-tillering, and seed production of P. bifurca. Variation in tissue nutrient concentration in response to N addition was most organ-dependent for Mg and Ca, most nutrient identity-specific for rhizomes and roots, while Mg, Fe, and Ca exhibited contrasting patterns between short- and long-term N addition. Conclusion Our findings highlight that trait-based mechanisms, especially those associated with regeneration processes, gap-detecting mechanism of seeds, and space-occupying mechanisms of seedlings, are involved in the response of dominant forb species to N enrichment in the temperate steppe.
