Older diplostomules from pre-exposures (in n = 223 sticklebacks) were larger and thereby discriminated from young diplostomules (in n = 224 sticklebacks, compare Figure 1) from the single exposures 1.5 and 5 days after the last exposure (compare Figure 3). Data were analysed with Generalized Linear Models (GzLM) with stickleback family nested in stickleback origin (lake/river).
