The Molecular Basis of Growth Control in Guanine Crystals. [PDF]

Small
Precise control over guanine crystal morphology is achieved through biologically inspired, facet‐selective interactions. Simple synthetic polymers tune growth from prisms to needles and plate‐like biogenic forms by modulating multivalency, polarity, and functional‐group identity.

Effects of Marine Toxin Domoic Acid on Innate Immune Responses in Bay Scallop Argopecten irradians

Journal of Marine Science and Engineering, 2019
Domoic acid (DA) is an amnesic shellfish poisoning toxin produced by some species of the genera Pseudo-nitzschia and Nitzschia. This toxin has harmful effects on various species, especially scallops.

Improving escape responses of hatchery-reared scallops Argopecten purpuratus

Marine Biology, 2011
Hatchery rearing of the scallop Argopecten purpuratus has resulted in successive generations of scallops not exposed to predators that are less sensitive to and escape more slowly from predators than wild scallops. The present study examined whether conditioning hatchery-reared A. purpuratus to its natural predator, the sea star Meyenaster gelatinosus,

The polymorphism in the promoter of HSP70 gene is associated with heat tolerance of two congener endemic bay scallops (Argopecten irradians irradians and A. i. concentricus). [PDF]

PLoS ONE, 2014
The heat shock protein 70 (HSP70) is one kind of molecular chaperones, which plays a key role in protein metabolism under normal and stress conditions.In the present study, the mRNA expressions of HSP70 under normal physiological condition and after ...

Reproductive Conditioning of the Peruvian Scallop Argopecten purpuratus in Different Environments

Fishes, 2023
Obtaining viable Argopecten purpuratus seeds faces challenges, especiallyci the unpredictability of the marine environment and high production costs in hatcheries. However, improving the method of "Broodstock Conditioning In Hatcheries" is key to ensure permanent seed supplies by minimizing the dependence on marine conditions and by maximizing economic

Host Defense Effectors Expressed by Hemocytes Shape the Bacterial Microbiota From the Scallop Hemolymph

Frontiers in Immunology, 2020
The interaction between host immune response and the associated microbiota has recently become a fundamental aspect of vertebrate and invertebrate animal health. This interaction allows the specific association of microbial communities, which participate

Life Cycle Assessments of Bivalve Aquaculture: A Systematic Review and Meta‐Analysis

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
Life cycle assessment (LCA) of bivalve aquaculture systems indicates generally low environmental impacts across mussel, oyster, and clam production. For a functional unit of 1 t live weight bivalves at farm gate, median impacts were 385 kg CO2‐eq for climate change, 0.25 kg PO43−‐eq for eutrophication, 0.014 kg N‐eq for marine eutrophication, 1.86 kg ...

Spawning and recruitment in the Peruvian scallop Argopecten purpuratus

Marine Ecology Progress Series, 1988
During a 15 mo period (February 1983 to May 1984), spawning and recruitment pulses of the Peruvian scallop Argopecten purpuratus were determined using information on gonad index, larval abundance and recruitment of scallop seed on the natural banks. In situ temperature was simultaneously recorded and showed a marked relation with spawning time as well ...
