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
