Widespread Variation in Retinochrome Spectral Absorbance Across Scallop Phylogeny
Molecular Ecology, Volume 35, Issue 11, June 2026.ABSTRACT Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a ...

The effect of octopaminergic compounds on the behaviour and transmission of
Parasites & Vectors, 2011 Background The high transmission potential of species belonging to the monogenean parasite genus Gyrodactylus, coupled with their high fecundity, allows them to rapidly colonise new hosts and to increase in number.

The Role of Octopamine and Tyramine in the Adult Female Reproductive System of Rhodnius prolixus [PDF]
, 2017 Octopamine and tyramine are neuroactive chemicals involved in many physiological processes acting as neurotransmitters, neuromodulators and neurohormones. Octopamine and tyramine modulate reproduction in insects.

Spider Mites: Genetic Models to Inform Herbivore and Chelicerate Biology
BioEssays, Volume 48, Issue 5, May 2026.Chelicerates include spiders, scorpions and ticks, and also spider mites that damage crops. Many of the features that make spider mites crop pests have facilitated their adoption as genetically tractable chelicerates. The expanding genetic toolkit developed using spider mites has potential to inform genetic studies in other chelicerates as well ...

Monoamines, Insulin and the Roles They Play in Associative Learning in Pond Snails
Frontiers in Behavioral Neuroscience, 2019 Molluscan gastropods have long been used for studying the cellular and molecular mechanisms underlying learning and memory. One such gastropod, the pond snail Lymnaea stagnalis, exhibits long-term memory (LTM) following both classical and operant ...

Journal of Food Science, Volume 91, Issue 5, May 2026.ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Study of Octopamine in Bivalves
The FASEB Journal, 2012 Octopamine (OA), a biogenic amine first identified in octopus, is well studied in arthropods and gastropods. Its presence and actions have rarely been reported in bivalves. Previously, we identified OA in ganglia and tissues of the oyster Crassostrea virginica (order Osteoida) and found it a ...
