Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods. [PDF]

Ecol Evol
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Gastropod chemoreception behaviors—Mechanisms underlying the perception and location of targets and implications for shellfish fishery development in aquatic environments

Frontiers in Marine Science, 2023
Chemoreception is one of the most important senses and it plays a key role in the survival and adaptation of animals to their environments. Many gastropods, such as Rapana venosa and Neptunea cumingii, have emerged as economically important shellfish ...

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)

Saxitoxin Group Toxins Accumulation Induces Antioxidant Responses in Tissues of Mytilus chilensis, Ameghinomya antiqua, and Concholepas concholepas during a Bloom of Alexandrium pacificum

Antioxidants, 2022
Saxitoxin (STX) group toxins consist of a set of analogues which are produced by harmful algal blooms (HABs). During a HAB, filter-feeding marine organisms accumulate the dinoflagellates and concentrate the toxins in the tissues.

The composition of phosphate granules in the digestive glands of marine prosobranch gastropods: variation in relation to taxonomy [PDF]

, 1998
The composition of some 1150 phosphate granules in the digestive glands of over 40 species of marine prosobranch gastropods has been surveyed using a simple preparation technique and semiquantitative SEM x-ray microanalysis. Spectral peaks for Mg, K, Ca,
