The Neural Control of Egg-laying Behaviour in the Pond Snail Lymnaea Stagnalis: Motor Control of Shell Turning

Role of neuropeptides encoded on CDCH-1 gene in the organization of egg-laying behavior in the pond snail, Lymnaea stagnalis.

Egg laying in the pond snail Lymnaea stagnalis is triggered by a discharge of the neuroendocrine caudodorsal cells (CDCs). The CDCs expresses three different caudorsal cell hormone (CDCH) genes. This gene family expresses, in total, 11 different peptides among which is the ovulation hormone. Besides the CDCs, the CDCH gene family is expressed in other central and peripheral neurons. In this stu...

Short Communication Neuronal Feedback in Egg-laying Behaviour of the Pond Snail Lymnaea Stagnalis

Characterization of mechanisms for Ca2+ and HCO3(-)/CO3(2-) acquisition for shell formation in embryos of the freshwater common pond snail Lymnaea stagnalis.

The freshwater common pond snail Lymnaea stagnalis produces embryos that complete direct development, hatching as shell-bearing individuals within 10 days despite relatively low ambient calcium and carbonate availability. This development is impaired by removal of ambient total calcium but not by removal of bicarbonate and/or carbonate. In this study we utilized pharmacological agents to target...

Molecular detection of the infection with Fasciola hepatica in field-collected snails of Galba truncatula and Lymnaea stagnalis from West Azarbaijan, Iran

The liver fluke, Fasciola hepatica, is considered as the most common cause of fasciolosis in both domestic livestock and human. This study was carried out to detect the prevalence of the larval stages of F. hepatica in the snails Galba truncatula and Lymnaea stagnalis in West Azarbaijan, Iran. Snail collection was performed through searching 28 freshwater habitats from May to December 2010. Fol...

Energy budgets in the simultaneously hermaphroditic pond snail, Lymnaea stagnalis : A trade-off between growth and reproduction during development

Maximum lifetime reproductive success is determined by the optimal partitioning of available resources between growth, maintenance and reproduction. The main question that is addressed here is how this resource allocation occurs in the simultaneously hermaphroditic pond snail, Lymnaea stagnalis. Snails were either reared in groups or in isolation and were fed a standard, restricted amount of le...
