摘要: Recent studies have shown that natural abundance stable carbon isotopes can be used to partition measurements of net ecosystem CO 2 exchange into gross fluxes photosynthesis and respiration. This chapter explores the related application isotope ratio respired partitioning components Although, exploitation variation in holds most promise for widespread among existing measurement networks (e.g., BASIN, FLUXNET, SIBAE) comparative focused on C balance, reliance may also limitations from standpoint such is typically small. evidence suggests, however, large significant measurable differences respiration signatures allow therefore inform C-balance studies.
