Diversity, productivity and landscape-level effects in North American grasslands managed for biomass production

摘要: Expanding markets for bioenergy will increasingly shape the composition and configuration of crop production. Growing interest in second-generation biofuels (e.g., lignocellulosic ethanol) is driving a discussion about most productive appropriate cropping systems. Interest perennial grasslands as source has many people asking importance plant community diversity bolstering productivity, resistance to pest pathogen pressure wildlife habitat, among other ecosystem services. We review current understanding diversity–productivity relationships across multiple spatial scales, but also emphasize perspectives that have received less attention literature.
