| Research Abstract |
Based on the sclerochronological, stable oxygen and carbon isotope, and rare and trace element analyses of lunar-day increment sequences of two bivalve species, Phacosoma japonicum and Mytilus galloprovincialis living in the intertidal environment of Tokyo Bay, central Japan, ecological and environmental controls on shell microgrowth have been investigated at daily time resolution. Furthermore, this approach was applied to Holocene fossil shells of P. japnocum, and response of life history traits to Holocene coastal climate change has been demonstrated at daily to seasonal time resolution.
