The dynamics of C in terrestrial ecosystems can be traced on the basis of the marked differences in the delta C-13 signatures of plants possessing the C-3, C-4 or CAM photosynthetic pathways. When two C sources differing in natural C-13 abundance (delta C-13) contribute to a mixture, the relative contribution of each can be quantitatively apportioned by the use of a two-end-member mixing model. This ability of delta C-13 to partition source is unique among stable isotopes important in the biosphere, where with few exceptions, natural abundance signatures are used as qualitative rather than quantitative tracers because of isotopic fractionation. The many and varied applications of delta C-13 in apportioning C source are examined herein. They include estimation of soil organic matter turnover due to either a known or presumed change in vegetation cover, the contribution of organic materials to the soil C pool, the contribution of C source to vertebrate and invertebrate diets, disentangling roots in mixed C-3-C-4 stands, and partitioning the sources of respired CO2 in various C-3-C-4 mixtures, i.e., between plants and soil, between plants, between animal excreta slurries and soil, within fungal media and within biochar-amended soil. |
