Table 3. Repeated measures ANOVAs and within subjects effects (parasite abundance/prevalence in the first and the second year) with laying date, clutch size, brood size, body condition and population density of hosts in two separate study years as within subjects factors and interactions between the repeated measure and latitude, temperature change, variation in parasitism (i.e. change in abundance and prevalence of parasites) and identity of parasite group as between subjects factors. P-values smaller than 0.05 are shown in bold.
