“…Hurst & Walker (1935) found that the snail Lymnaea stagnalis appressa (Say, 1821) parasitized by larvae of the trematode Echinostoma revolutum (Fröhlich, 1802) had a heat output 2.7 times higher than that of unparasitized snails. In contrast, Duerr (1967) found that the metabolic activity of Lymnaea stagnalis appressa (Linnaeus, 1758) was reduced by digenetic trematodes. However, this finding was based on comparisons between field-collected parasitized snails and laboratory-reared control snails, and no tests were conducted to establish if the differences in metabolism were a result of environment rather than parasitism.…”

The daggerblade grass shrimp Palaemonetes pugio Holthuis, 1949 is prevalent in estuaries along the East and Gulf coasts of the United States, and is an integral part of the estuarine food web. Probopyrus pandalicola (Packard, 1879) is a bopyrid isopod that parasitizes P. pugio and decreases the energy available to its host by feeding on the hemolymph of the shrimp. The parasite also causes female shrimp to be castrated. The purpose of this study was to determine the effect of Probopyrus pandalicola on the survival time of P. pugio during starvation at two different temperatures. The experiment was conducted between September 2009 and June 2012 at 20.0 ± O.irC and 25.0 ± 0.10°C. Three trials at each temperature were performed. For each trial, parasitized, deparasitized and unparasitized shrimp were randomly placed into individual aquaria in a temperature-controlled chamber. All trials lasted until 100% shrimp mortality occurred. The bopyrid isopod did have a significant effect on shrimp survival times, but only at the higher temperature during which parasitized shrimp survived a significantly shorter amount of time (21.8 ± 6.93 days) than unparasitized shrimp (25.2 ± 8.25 days). In contrast, the bopyrid did not have a significant effect on shrimp survival times at the lower temperature, with shrimp surviving an average of 26.9-27.5 days. The results of this study have implications related to potential climate change, specifically higher temperatures, as we found that a small increase in temperature significantly affected the response of P. pugio to the isopod parasite. This supports prior research on other host-parasite interactions that are affected by increased temperature. RESUME La crevette bouquet Palaemonetes pugio Holthuis, 1949 est fréquente dans les estuaires le long des côtes Est et du Golfe des Etats Unis, et elle fait partie intégrante de la chaine alimentaire.

Le parasite provoque aussi la castration des femelles. Le but de cette étude a été de déterminer les effets de Probopyrus pandalicola sur le temps de survie de P. pugio au cours d'un jeûne à deux températures différentes. L'expérience a été conduite entre Septembre 2009 et Juin 2012 à 20,0 ± O,irC et 25,0 ± 0,10°C. Trois essais ont été effectués à chaque température. Pour chaque essai, des crevettes parasitées, déparasitées et non parasitées ont été placées au hasard dans des aquariums individuels dans une chambre à température contrôlée. Tous les essais ont duré jusqu'à la mort de 100% des crevettes. Les isopodes bopyridés ont eu un effet significatif sur les temps de survie, mais seulement à la plus haute température, pour laquelle les crevettes parasitées survivent un laps de temps plus court (21,8 ± 6,93 d [= jours]) que les crevettes non parasitées (25,2 ± 8,25 d). Par contre les bopyridés n'ont pas eu d'effet significatif sur les temps de survie des crevettes à la plus basse température, avec u...

“…However, the effect of parasitism on the metabolic rate of the snails is highly variable and depends on the parasite's type. The metabolic rate of L. stagnalis infected with digenetic trematodes that shed so-called Strigea cercariae (like D. pseudospathaceum does) is affected more than that of L. stagnalis infected with trematodes that shed xiphidiocercariae (like P. elegans does) (Duerr, 1967).…”

“…they were less hungry than their unparasitized conspecifics because the demand for energy of the snails was lowered as a result of the infection. In general, trematode parasitism lowers the metabolic rate of the parasitized L. stagnalis (Duerr, 1967). However, the effect of parasitism on the metabolic rate of the snails is highly variable and depends on the parasite's type.…”

-Four experiments were serially carried out conducted to study foraging activity in the freshwater gastropod Lymnaea stagnalis in the absence and presence of predators (crayfish or fish) under daylight and in the dark. The snails were either parasitized by digenean trematodes (Diplostomum pseudospathaceum or Plagiorchis elegans) or remained unparasitized. The snails had an evident circadian foraging rhythm: they preferred diurnal foraging notwithstanding the predators and parasites. However, the snail's parasite status and the predation risk had an interaction effect on the number of feeding events per snail individual so that especially the snails parasitized by D. pseudospathaceum were more active in the presence of a fish predator than in the absence of predators. Some of the snails responded to cues from a crayfish predator by crawling out of the water. The results suggest that D. pseudospathaceum may be capable of manipulating the behaviour of its first intermediate snail host in ways that enhance its success of transmission to the parasite's second intermediate fish host. The results also indicate that the effects of biotic stressors, such as predation risk and parasitism, on the foraging pattern in the snails L. stagnalis may be interactive and highly specialized rather than generalized.
