Replicates were nested within periwinkles, and periwinkles nested within experimental condition. Means were calculated from the longevity of cercariae from 3 periwinkles (100 cercariae per periwinkle). Mean values represent the fastest 10 cercariae of 10 replicates carried out for 3 cercarial releases from different periwinkles. Some differences in swimming rate and longevity between cercariae originating from different ' clean ' periwinkles were found, but only for cercariae exposed to heavy metal solutions. Noticeable differences in shell shape of parasitized and uninfected periwinkles were investigated. The periwinkle was removed after the allotted time and the shell height measured and recorded. This protocol was repeated 10 times for each batch of cercariae from each periwinkle, taking less than 30 min per batch. Using mounted needles the reproductive tissue and digestive gland were teased apart to ascertain the presence/absence of periwinkle brood or trematode presence. For each test seawater solution 10 replicate trials using cercariae from each of 3 periwinkles were carried out. It remains an open question whether young children can benefit from a more implicit form of contrast (as in the ' periwinkle ' example above). The periwinkle effects found for longevity of cercariae released by periwinkles from polluted sites are also consistent with varying tolerance, although they could reflect differing metal accumulation. It was also confirmed that periwinkles were not affected. From the Hansard archive Example from the Hansard archive.
