| Outline of Final Research Achievements |
Planktonic foraminifers are the most useful microfossil as ocean environmental proxy. However, the previous biological studies have pointed out that their taxonomic complexity veil the true ecological trait of each biological species. This study aimed to develop and apply the new approach, which comprehensively conduct the molecular, morphometric, and geochemical analyses, on an individual of planktonic foraminifers. First, we precisely examined the DNA extraction method has no physical or chemical damages to the foraminiferal shells, by using the leading-edge technologies. Then, we measured the morphological characters of the shells, and oxygen and carbon stable isotopes for each individual. Finally, we succeeded to detect morphological and isotopic differences between different biological species. Our novel approach is available for broad fossilized organisms to advance the understanding of their ecological characters, which could be worked for development of new multiple proxies.
