To validate the periodicity of formation of growth rings, we evaluated the seasonal changes in the following two indices: (1) the proportion of specimens with a hinge plate showing recent formation of a marginal growth ring and (2) the mean marginal growth index (MGI), which is derived from the SH data for relevant growth rings in cross-sections (discussed later).
