Note: Abbreviation ‘Coeff.’ indicates the coefficient of each variable in GLM. Positive values for the coefficient of the variable ‘Gene (nu)’ indicate higher eDNA decay rate constant for nuclear than mitochondrial DNA. Positive values for the coefficient of the variable ‘Water source (fre/sea)’ indicate higher eDNA decay rate constant for freshwater or seawater than artificial water samples. The coefficient of the interaction ‘Gene (nu): Water source (fre)’ was not analysed because no study described eDNA decay rate constants using a nuclear DNA marker and freshwater samples. P values of each parameter are not shown in the model, except for the full model. Coefficients of each parameter are shown in bold.
