Table 1 Effect of parasite population, food treatment and host size on the infection intensity

From: Influence of host nutritional condition on post-infection traits in the association between the manipulative acanthocephalan Pomphorhynchus laevis and the amphipod Gammarus pulex

Source of variation d.f. LR-χ2 P
Parasite population 1 52.48 <0.0001
Food treatment 1 1.22 0.27
Gammarids size 1 0.02 0.89
Parasite population x Food treatment 1 8.06 0.004
  1. Whole model: χ2 = 57.86, d.f. = 4, P <0.0001
  2. Generalized linear model analysing the effect of parasite population, food treatment and gammarid size on the infection intensity (number of parasites harboured by gammarid hosts). A quasi-Poisson error term and a log link-function were used. The model presented here minimized the AIC criterion
