Grassland diversity enhances productivity at low and high levels of nitrogen addition
A central theory of ecology postulates that ecosystem processes in more diverse ecosystems are more stable than in less diverse ones, especially when environmental changes occur.Thus, diversity can provide insurance for some ecosystem function responses, such as biomass production ( Yachi & Loreau, 1999 ).This study quantifies the contribution of species identity and evenness to biomass production in mixed grassland systems under different N addition regimes.
