Fig. 2 Four modes of variability for carbon and nitrogen stable isotope ratios (&#948;¹³C and &#948;<sub>15</sub>N) of vertebral sectional collagen of Japanese flounder in Sendai Bay, Japan, obtained by nonlinear time-series analysis. Vertebral section numbers start at the center of the vertebral centrum and increase toward the margin. Vertical lines show estimated breakpoints between years one, two, and three of individuals (i.e., vertebral section numbers 6,12, and 18). For example, individuals in N55 showed lower &#948;<sub>15</sub>N values than those in other sampling sites throughout most of their lifetimes in the mode 1, indicating that the mode 1 shows individual differences among sites.
