Trait–Abundance Relationships of Annual Ephemerals in Response to Nitrogen Addition in Gurbantunggut Desert

Understanding the effect of nitrogen addition on species trait–abundance relationships is one central focuses community ecology and can offer us insights into mechanisms assembly under atmospheric deposition. However, few studies have focused desert ecosystems. In this study, we measured abundance ecological stoichiometric traits, leaf carbon content (LCC), (LNC), phosphorus (LPC) for all annual ephemerals in plots subjected to early spring Gurbantunggut Desert, northern Xinjiang, China. We found a significant relationship between traits (LNC, N:P, C:N) abundance, indicating that stoichiometry good proxy explaining predicting abundance. further still existed different levels. The result suggests trait-based niche-assembly theory plays an important role determining
