Outline of Final Research Achievements

We tried to demonstrate the utility of concentrations of rare elements and isotope ratios of heavy elements, which have not been well studied in the field of ecology for studying migratory patterns.
We analyzed strontium isotope ratios and Sr/Ca ratios of whole otoliths in three-spined sticklebacks (Gasterosteus aculeatus) caught at the coastal areas of Iwate, Japan. Strontium isotope ratios of otoliths and water in one tidal tributary showed that the sticklebacks caught at the upstream sites inhabited only within the upstream, but the sticklebacks caught at the downstream sites inhabited not only in the downstream but also in the upstream or the near mainstream sites.
Then, we measured the concentrations of Nd and Pb in goby species caught at several places in Japanese coasts. These elements were higher in gills and digestive organs that are connected directly with the outer environment than the rest of body.
