Table 1.
Analysis of deviance table and model diagnostics from linear mixed-effects models of deuterium incorporation for adults and larvae. (Model statistics are from a log-likelihood ratio comparing the full model with an intercept only model. χ2, degrees of freedom and p-values (p) are calculated from Wald-type III tests. R2 values are marginal (R2GLMM(m)) and conditional (R2GLMM(c)) R2 values that describe the proportion of the variance explained by the fixed factors and all factors, respectively [36].)
