Life-history trade-offs in a generalist digenean from cetaceans: the role of host specificity and environmental factors

Table 4 General Linear Mixed Models with type III sum of squares accounting for the effect of host species (factor) and worm body area (covariate) on egg area of individuals of the digenean Pholeter gastrophilus collected from striped and bottlenose dolphins

Models are arranged by increase of Akaike information criterion (AIC) and decrease of Akaike weight (w _i). Models with w _i < 0.01 are not shown. The probability associated to each fixed effect is also given; significant values are in bold. Abbreviations: BA worm body area, HI host individual, RI random intercept, RS random slope, HS host species
