Effects of grazing and fertilization on the relationship between species abundance and functional traits in an alpine meadow community on the Tibetan Plateau

摘要: Trait-based approaches can provide a useful tool for linking plant attributes to community structure and ecosystem function. Seed mass height play important roles in the dynamics of communities, but few empirical level studies have tested this, especially stressful environments. The aim present study was determine if there is relationship between functional traits (seed height) changes species relative abundance (SRA) response grazing fertilization. We measured SRA 40 common Tibetan Plateau alpine meadow. In fertilized meadow, seed significantly positively correlated with species. grazed these variables were negatively correlated. Our results demonstrates that be used predict change community. Grazing promotes dominance small-seeded short-stature species, fertilization facilitates occurrence large-seeded tall-stature
