the prevalence of cercariae from stagnicola emarginata (lymnaeidae) over 50 years in northern michigan.	stagnicola emarginata were collected from 3 northern michigan lakes and examined for larval trematode infections. the structure of the trematode community was then compared with 2 previous studies conducted on douglas lake in order to determine what changes had taken place over a period of more than 50 yr and to examine the possibility of using trematodes as bioindicators of environmental quality. species richness was reduced by half (from 16 to 8 species) from the first study conducted in 1936, ...	1997	9194844
ubiquitous variability in the prevalence of trichobilharzia stagnicolae (schistosomatidae) infecting stagnicola emarginata in three northern michigan lakes.	during 4 consecutive collecting seasons from 1998 through 2001, 77,326 common beach snails (stagnicola emarginata, lymnaeidae) were examined for infections by trichobilharzia stagnicolae from multiple sites on walloon lake, higgins lake, and lake leelanau, located in the northern region of the lower peninsula of michigan. snails were examined for infections using the light-box technique (exposure to bright fluorescent light). the prevalence of infected snails varied significantly among lakes wit ...	2006	16629307
