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 ...

Integrated Study of New Faunal Assemblages Dominated by Gastropods at Three Vent Fields Along the Mid-Atlantic Ridge: Diversity, Structure, Composition and Trophic Interactions

Frontiers in Marine Science, 2022
To date, two main vent faunal assemblages have been described on active sulfide edifices along the northern Mid-Atlantic Ridge (nMAR): one dominated by bathymodiolin mussels in low temperature areas and the other dominated by alvinocaridid shrimp in ...

Key Determinants of Freshwater Gastropod Diversity and Distribution: The Implications for Conservation and Management

Water, 2020
Freshwater organisms are facing threats from various natural and anthropogenic disturbances. Using data sampled on a nationwide scale from streams in South Korea, we identified the crucial environmental factors influencing the distribution and abundance ...

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 ...

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.

Intra- and Interspecific Foraging and Feeding Interactions in Three Sea Stars and a Gastropod from the Deep Sea

Biology, 2023
Competitive interactions come in a variety of forms and may be modulated by the size and number of individuals involved, and/or the resources available.

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.

THE EVOLUTION OF APOSEMATISM IN MARINE GASTROPODS [PDF]

Evolution, 1991
In a recent review of the literature on marine gastropods, Rosenberg (1989) concludes that in this group,".. . as in the lepidopterans, . . . individual selection is the predominant mode of evolution of warning coloration." Rosenberg's analysis raises interesting issues concerning the evolution of aposematism generally, and in marine gastropods in ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)
