High-time resolution reconstruction of the organism-environmentinteraction by using modern and fossil mollusk shell microincrements

本文通过对日本东京湾潮间带环境中两种双壳类物种（Phacosoma japonicum和Mytilus galloprovincialis）的月相日增量序列、稳定氧碳同位素、稀土和微量元素分析，探讨了日分辨率下壳微生长的生态环境控制因素。此外，将该方法应用于全新世日本斑鲷化石壳，并在日至季节的时间分辨率上证明了生活史特征对全新世海岸气候变化的响应。

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.
