In regards to Theresa Stevens inquiry, there is a section in a paper by
C. Combes, A Fournier, H. Mone, and A. Theron (1994. Behaviors in
trematode cercariae that enhance parasite transmission: patterns and
processes. Parasitology 109:S3-S13) on page S8 that deals with the
selective pressures associated with the predation of cercaria by non-host
species. - Derek A. Zelmer
