Abstract	Aims Niche complementarity theory explains how species coexist by using different resources. Two pathways to partition resource have been demonstrated: classical niche differentiation and plasticity in resource use. We aimed to determine N-uptake patterns in three Tibetan Plateau grassland species, and to examine how N-partitioning is driven by neighbor interactions. Methods We conducted a transplantation experiment using ten plant communities, each comprising a different combination of Kobresia humilis, Stipa aliena, and Saussurea superba. Soil was sprayed uniformly with a mixture of (NH4)(2)SO4, KNO3, and glycine (C2H5NO2) (1:1:1 by mass of N, each containing one form of N-15) after growing for 45 days. Results Across three species, the N-uptake pattern was NO3- > NH4+ > glycine (NO3-: 58.47%; NH4+: 26.91%; glycine: 14.62%). Neighbor presence had species-specific effects on N-15 recovery. Kobresia humilis took up more N-15-NO3- when it was in competition with other species, whereas Stipa aliena and Saussurea superba took up more N-15-NH4+ and N-15-glycine, respectively. Conclusions Plasticity in N resource utilization of the three species was limited. The species competed for N resources proportionally to the availability of these sources, and tended to partition niches. These findings provide important insights into how plant species grow together in alpine grasslands.
