Monoamines, Insulin and the Roles They Play in Associative Learning in Pond Snails

Frontiers in Behavioral Neuroscience, 2019
Molluscan gastropods have long been used for studying the cellular and molecular mechanisms underlying learning and memory. One such gastropod, the pond snail Lymnaea stagnalis, exhibits long-term memory (LTM) following both classical and operant ...

Octopamine increases the excitability of neurons in the snail feeding system by modulation of inward sodium current but not outward potassium currents [PDF]

, 2005
Background: Although octopamine has long been known to have major roles as both transmitter and modulator in arthropods, it has only recently been shown to be functionally important in molluscs, playing a role as a neurotransmitter in the feeding network

First Report of Fascioliasis of Ruminants in the Kharaa River Basin and Identification of Snail Hosts in Mongolia

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Fascioliasis is a parasitic liver disease of mammals induced by liver flukes, Fasciola hepatica and Fasciola gigantica. Fasciola spp. rely on their definitive hosts, ruminants, and intermediate hosts, snails, to survive and can incidentally infect humans as definitive hosts. Ruminant (goat, sheep, and cattle) liver and fecal samples were collected from

Stochastic variation in temperature and food availability impacts growth, but not metabolic rate and exploration in a juvenile amphibian

Functional Ecology, Volume 39, Issue 12, Page 3405-3416, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A substantial proportion of environmental variation is stochastic. While environmental stochasticity plays a key role in the evolution of phenotypic strategies, its short‐term effects within generations remain poorly understood. These short‐term organismal responses are

The Lymnaea Cardioexcitatory Peptide (LyCEP) Receptor: A G-Protein–Coupled Receptor for a Novel Member of the RFamide Neuropeptide Family [PDF]

, 1998
A novel G-protein–coupled receptor (GRL106) resembling neuropeptide Y and tachykinin receptors was cloned from the molluscLymnaea stagnalis. Application of a peptide extract from the Lymnaea brain to Xenopus oocytes expressing GRL106 activated a calcium ...

Cryptic Reproductive Costs of Heatwaves for Animal Populations

Global Change Biology, Volume 31, Issue 11, November 2025.
Heatwaves are among the most serious threats posed by climate change to biodiversity. They are known to cause mass mortality events in animals and to strongly affect animal reproduction. The impact of heatwaves on reproduction is crucial because it occurs across all stages, from gamete formation to offspring number and development and beyond.

Effect of mefloquine on biological and biochemical aspects of Lymnaea natalensis snails infected with Fasciola gigantica

Journal of Basic and Applied Zoology, 2019
Background The effect of the mefloquine drug on the survival rate, egg production, and infection of snails with Fasciola gigantica was studied. Also, the present study was designed to investigate the response of the snail Lymnaea natalensis for ...

Suppression of nitric oxide (NO)-dependent behavior by double-stranded RNA-mediated silencing of a neuronal NO synthase gene [PDF]

, 2002
We have used double-stranded RNA (dsRNA)-mediated RNA interference (RNAi) to disrupt neuronal nitric oxide (NO) synthase (nNOS) gene function in the snail Lymnaea stagnalis and have detected a specific behavioral phenotype.
