Isotopic, biochemical and ecological structure can provide a new dimension for understanding material flows, and the simultaneous function and strucute of an ecosystem. Distribution of 13C and 15N for biogenic substances in the Nanakita river estuary involving Gamo lagoon in Japan were investyigated to construct isotope biochemical and ecological structure for assessing fate and transfer of organic matter, and food web structure. The isotopic framework on the ecosystem was successfully described in a 15N-13C map. In this estuary the variations of isotope ratios of biogenic substances were clearly explained by the mixing of land-derived organic matter, and marine-derived organic matter. A trophic-level effect of 15N enrichment was clearly observed. Organisms were classified into three groups depending upon the contribution of land-derived organic matter in a food chain. Almost all biota except mollusca in the lagoon depend on organic matter of marine origin. The constributions of both land and marine organic were comparable for mollusca in the lagoon. |
