Background/Question/Methods
Ecosystem structure, functioning, and stability have been a focus of ecological and environmental sciences during the past two decades. However, the mechanisms that link them are not well understood. We took three approaches to test the relationship of stoichiometric homeostasis with species dominance, ecosystem functioning, and stability. These involved a two-year field N and P addition experiment, a long-term (27 years) observational data set of grassland excluded from sheep grazing, and a 1200-km spatial transect across the Inner Mongolia grassland.
