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.

size, target gene, and water temperature on eDNA decay rate constants.
