| Outline of Final Research Achievements |
Estuarine habitats are common ecotones that receive both riverine and marine materials. I have observed the essential role of allochthonous resources in the species diversity of estuarine faunal communities. I undertook field surveys of several estuaries of the Izu peninsula in Japan, and analyzed carbon and nitrogen stable isotopes of organisms to determine the utilization patterns of allochthonous resources for estuarine animals. The results have indicated that estuarine fauna utilize marine and riverine allochthonous resources and that faunal diversity is influenced by the abundance of allochthonous resources.
