Estimated Coefficients for effects of covariates on total abundance of parasites.

<p>Fit of a generalized linear model (GLM) contrasted to Bear Island and female, assuming a negative binomial response. Note that total length and Fulton's K are standardised, so the coefficient represents the change in log abundance when the covariate (e.g. total length) changes by one standard deviation.</p

Model-based unconstrained and residual ordination biplot for the <i>S</i>. <i>mentella</i> parasite community among fishing grounds.

<p>Latent variable model (with two latent variables). I) Unconstrained ordination with no predictors: Fish of Greenland clusters apart from fish of the other two locations II) Residual ordination after controlling for the effect of fishing grounds: No visible pattern. Each number represents one fish specimen with the colours depicting its origin. Parasite species and fish specimen in the same direction are highly correlated.</p

Posterior estimates of effects of covariates on the abundance of parasite species.

<p>Points: posterior mean, Lines: 95% Highest Posterior Density Interval. Fishing grounds Greenland and Tampen are contrasted to Bear Island. The darker the estimate, the higher the evidence of an effect.</p

Median joining network of <i>Anisakis simplex</i> s.s haplotypes from <i>cox2</i> mitochondrial DNA sequences (n = 80), inferred from statistical parsimony.

<p>The size of pie charts corresponds to the frequency of haplotypes. Black nodes represent hypothetical haplotypes that were required for the establishment of the sampled haplotypes. Blue = Greenland, red = Tampen, green = Bear Island, H = haplotype with the according number.</p

Genetic variability and Tajima’s D per fishing ground and pooled.

Map of fishing grounds with relative distributions of parasite groups.

<p>Large pie charts: all parasite groups, small pie charts: proportion of parasite groups excluding Nematoda. I: East Greenland, II: Tampen, northern North Sea, III: Bear Island, Barents Sea. The map was modified from Klapper et al.
