Table 2.

Coefficients of the best general linear model (GLM), with parasite PAHm concentration as dependent variable and four independent variables. The asterisk indicates statistical significance of the coefficient (P < 0.05). Values of the Akaike information criterion (AIC) of the distributions tested for the Generalized Lineal Model (GLM) are shown in Table S9
