The results obtained indicated that NHS had variable effects on basic population parameters of host infection. Specifically, NHS were able to produce aggregation of sporocyst number\/snail in the experimental host populations. Proposed hypotheses for decoy effect mechanisms failed to explain completely the experimental results. A new mechanism is suggested, based on a distance response of miracidia to snail chemo-attractants, to explain effects of NHS on miracidial host finding behaviour. It is assumed that miracidia have evolved the ability to discriminate among individual snail chemical attractants in a community already at a distance. This attribute of miracidial behaviour allows NHS to induce variations in the effectiveness of individual host localization by miracidia. The resulting aggregation of successful infections\/host is assumed to be the specific component of snail decoy effect at the community level. It was also established that NHS affected trematode reproduction in the host inducing a compensatory increase in the intramolluscan population. Intraspecific competition among developmental stages is suggested to be the mechanism of this compensatory reaction.<\/jats:p>","DOI":"10.1017\/s0031182000075089","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T14:12:16Z","timestamp":1244211136000},"page":"265-276","source":"Crossref","is-referenced-by-count":10,"title":["Decoy effect and host infection by miracidia within snail communities"],"prefix":"10.1017","volume":"106","author":[{"given":"N.
