Figure 1.
Illustration of the conceptual decay processes of 137Cs activity concentration in fish bodies.
Figure 2.
Effects of ecological/biological traits of species on maximum day of 137Cs activity concentration in fish.
Effects of a) trophic position of species, b) body mass (g, wet weight) of species, and c) inverse temperature (1/kT) of the environment on log10 maximum day (day) of 137Cs activity concentration in fish. Line indicates a significant relationship by the best GLMM, with the coefficient and intercept estimated by GLMM.
Figure 3.
Effects of ecological/biological traits of species on half-lives of 137Cs activity concentration in fish.
Effects of a) trophic position of species, b) body mass (g, wet weight) of species, and c) inverse temperature (1/kT) of the environment on log10 half-lives (day) of 137Cs activity concentration on fish. Lines indicate a significant relationship by the best GLMM, with the coefficient and intercept estimated by GLMM.
Figure 4.
Effects of ecological/biological traits of species on decay rate of 137Cs activity concentration in fish.
Effects of a) trophic position of species, b) body mass (g, wet weight) of species, and c) inverse temperature (1/kT) of the environment on log10 decay rate (day−1) on 137Cs activity concentration in fish. Lines indicate a significant relationship by the best GLMM, with the coefficient and intercept estimated by GLMM.

Figure 5.
The long-term trends and habitat/diet types of species.
Box and whisker plots of the indices of long-term trends (maximum day, half-lives, and decay rate) for different habitat and diet types of fish species. For diet types, B, B-P, P-B, and plant refer to benthos, benthos and plankton (benthos>plankton), plankton and benthos (plankton>benthos), and plant. Bars in the boxes, upper and lower box edges, and error bars indicate median, ±25% quantile, and 1.5×±25% quantile, respectively. There were no significant differences among the types for all indices (see Tables 1, 2, and 3).
