Differences in embryo morphological traits were driven by the developmental environment, whereas the maternal environment and interactive effects of maternal...

Theodoxus fluviatilis is a neritid gastropod that is distributed not only in limnic habitats in Europe but also in brackish waters (e.g. along the shoreline of the Baltic Sea). Animals from brackish sites survive better in high salinities than animals from freshwater locations...

...) corresponded ( Fig. 3 ). The presence of β-arrestin throughout the brain tissue reflects the fact that a single β-arrestin functions in terminating all G-protein signaling in gastropods. Neural tissues generally express higher levels of β-arrestin proteins than non-neural tissues ( Gainetdinov et al., 2004...

The humpbacked conch ( Gibberulus gibberulus gibbosus ), inhabiting subtidal zones of the Great Barrier Reef, was chosen as a model because vigorous jumping, causing...

These conclusions are the first explicit confirmation of odour-gated rheotaxis as a navigational strategy in gastropods and are also...

Results indicate that a panoply of antioxidant and molecular chaperone defences may be involved during the activity–estivation cycle in this freshwater gastropod.

...S. W. Werneke; C. Swann; L. A. Farquharson; K. S. Hamilton; A. M.

Specific glue proteins have been identified that play a central role in this adhesion...
