There are 2 parasitic stages in avian schistosomes life cycles: Adult worms, which live in the definitive host, most commonly a waterfowl species, and sporocysts, which live in an intermediate host, always a certain species of snail.So if humans aren’t part of the natural life cycle of these parasites, how do they end up causing swimmer’s itch? 257. We here examine variation in inbreeding depression, heterosis, and outbreeding depression on life-history traits across a full-life cycle, within a metapopulation of the hermaphroditic snail Physa acuta. Proximal factors had by far the greatest effects on life history traits in the transfer experiment, with snails reared in a more productive pond showing earlier reproduction at a larger size, higher fecundity, and longer life cycle length.
