Understanding the net effects of pesticides on amphibian trematode infections
TL;DR: The reduction in exposure to trematodes due to pesticides-induced cercarial mortality was smaller than the pesticide-induced increase in amphibian susceptibility (a trait-mediated effect), suggesting that the net effect of exposure to environmentally realistic levels of pesticides will be to elevate amphibian trematode infections.

Review of the trematode genus Ribeiroia (Psilostomidae): ecology, life history and pathogenesis with special emphasis on the amphibian malformation problem.
TL;DR: Important aspects of the biology, ecology, life cycle and pathogenesis of parasites in the genus Ribeiroia are reviewed and particular importance for future research is placed on evaluating the phylogenetic position of the genus, establishing the molecular mechanism of parasite-induced malformations in amphibians and isolating the drivers of parasite transmission under field conditions.
Journal ArticleDOI
Relationship of tadpole stage to location of echinostome cercariae encystment and the consequences for tadpole survival.
TL;DR: Exposures of metamorphic frogs to cercariae revealed that these individuals can become infected with echinostomes, and highlighted the host stage–dependent dynamics of tadpole–echinostome interactions.
Journal ArticleDOI
Parasite influences on host life history: Echinostoma revolutum parasitism of Lymnaea elodes snails
TL;DR: It is found that parasitism significantly affected the growth, fecundity, and survival of host snails, and gigantism occurs among experimentally infected snails due to an accelerated growth rate and size-selective mortality following an Echinostoma revolutum infection.
Journal ArticleDOI
Echinostome infection in green frogs (Rana clamitans) is stage and age dependent
TL;DR: Histopathological analysis supported the hypothesis that echinostome-induced tadpole mortality resulted from compromised renal function, and suggested that the timing of highest cercarial shedding can coincide with the most vulnerable stages of green frog tadpole development, which could significantly impact green frog survival in nature.

A Mark-Recapture Study of Trematode Parasitism in Overwintered Helisoma anceps (Pulmonata), with Special Reference to Halipegus occidualis (Hemiuridae).
TL;DR: Les caracteristiques du parasitisme par le trematode dans la cohorte d'escargots sont etudiees and une methode de marquage-lâcher-recapture est utilisee pour suivre le cours des infections.

The Morphology of the Amphistome Cercaria, C. poconensis Willey, 1930, from the Snail, Helisoma antrosa
TL;DR: During the course of a survey in I929 of the larval trematodes infecting snails of the species Helisoma antrosa from a small pond in the Pocono Mountains at Henryville, Pennsylvania, I6 snails were found to be infected with a new amphistome cercaria.
