A Phylogenomic Backbone for Gastropod Molluscs

Systematic Biology, 2022
AbstractGastropods have survived several mass extinctions during their evolutionary history resulting in extraordinary diversity in morphology, ecology, and developmental modes, which complicate the reconstruction of a robust phylogeny. Currently, gastropods are divided into six subclasses: Caenogastropoda, Heterobranchia, Neomphaliones, Neritimorpha ...

Sialic acids in gastropods [PDF]

FEBS Letters, 2001
The occurrence of N‐acetylneuraminic acid and N‐glycolylneuraminic acid residues in preparations of the slug Arion lusitanicus (Gastropoda) was determined by sodium dodecyl sulphate electrophoresis of the proteins followed by lectin blots stained with the sialic acid specific lectin from Maackia amurensis, by the sensitivity of this binding to ...

A problematic zygopleuroid gastropod Acanthostrophia revisited [PDF]

, 2010
SEM examination of the type series of Acathostrophia acanthica CONTI & FISCHER, 1984 from Middle Jurassic of Italy has shown that this gastropod most likely belongs to the family Protorculidae as previously suggested by NÜTZEL (1998). It is also similar

The Giant Marine Gastropod Campanile Giganteum (Lamarck, 1804) as a High‐Resolution Archive of Seasonality in the Eocene Greenhouse World

Geochemistry, Geophysics, Geosystems, 2020
Giant gastropods are among the largest mollusks in the fossil record, but their potential as paleoseasonality archives has received little attention.

In the sea slug Melibe leonina the posterior nerves communicate stomach distention to inhibit feeding and modify oral hood movements

Frontiers in Physiology, 2022
The sea slug Melibe leonina is an excellent model system for the study of the neural basis of satiation, and previous studies have demonstrated that stomach distention attenuates feeding.

Resilience of Atlantic Slippersnail Crepidula fornicata Larvae in the Face of Severe Coastal Acidification

Frontiers in Marine Science, 2018
Globally, average oceanic pH is dropping, and it will continue to decline into the foreseeable future. This ocean acidification (OA) will exacerbate the natural fluctuations in pH that nearshore ecosystems currently experience daily, potentially pushing ...

Morphological Properties of Gastropod Shells in a Warmer and More Acidic Future Ocean Using 3D Micro-Computed Tomography

Frontiers in Marine Science, 2021
The increased absorption of atmospheric CO2 by the ocean reduces pH and affects the carbonate chemistry of seawater, thus interfering with the shell formation processes of marine calcifiers.

Impact of the Antidiabetic Drug Metformin and Its Transformation Product Guanylurea on the Health of the Big Ramshorn Snail (Planorbarius corneus)

Frontiers in Environmental Science, 2019
Pharmaceuticals can enter surface waters via sewage treatment plants. In the environment, the substances and their transformation products, formed by the degradation of the parent compounds, can affect aquatic wildlife, including freshwater invertebrates.
