Published: April 27, 2024

Marine molluscs are of enormous scientific interest due to their astonishing diversity in terms size, shape, habitat, behaviour, and ecological roles. The phylum Mollusca is the second most common animal phylum, with 100,000 200,000 species, marine among notable class organisms. This work aimed show importance as a potential source nutraceuticals well natural medicinal drugs. In this review, main classes molluscs, chemical ecology, different techniques used for extraction bioactive compounds have been presented. We pointed out nutraceutical such proteins, peptides, polysaccharides, lipids, polyphenolic pigments, enzymes, minerals, vitamins. Their pharmacological activities include antimicrobial, anticancer, antioxidant, anti-inflammatory, analgesic activities. Moreover, certain like abalones mussels contain unique applications, ranging from wound healing anti-cancer effects. Understanding nutritional therapeutic value highlights significance both pharmaceutical dietary realms, paving way further research utilization human health.

Ocean acidification alters foraging behaviour in Dungeness crab through impairment of the olfactory pathway

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(14), P. 4126 - 4139

Published: May 9, 2023

Crustacean olfaction is fundamental to most aspects of living and communicating in aquatic environments more broadly, for individual- population-level success. Accelerated ocean acidification from elevated CO2 threatens the ability crabs detect respond important olfactory-related cues. Here, we demonstrate that ecologically economically Dungeness crab (Metacarcinus magister) exhibits reduced antennular flicking responses a food cue when exposed near-future levels, adding growing body evidence impaired behaviour. Underlying this altered behaviour, find have lower olfactory nerve sensitivities (twofold reduction activity) response . This suggests levels will impact threshold detection by crabs. We also show sensitivity accompanied decrease sensory neuron (OSN) expression principal chemosensory receptor protein, ionotropic 25a (IR25a) which odorant coding signalling cascades. The OSNs exhibit morphological changes form decreased surface areas their somata. study provides first effects high at multiple biological organization marine crabs, linking physiological cellular with whole animal behavioural responses.

Evidence of the Existence of Site-Specific Female Contact Pheromones Involved in the Sexual Interaction Behavior of the Pacific Whiteleg Shrimp Penaeus vannamei

Animals, Journal Year: 2024, Volume and Issue: 14(11), P. 1523 - 1523

Published: May 22, 2024

Although the presence of female contact sex pheromones in P. vannamei has been hypothesized, to date its existence not proven. To gather more evidence their existence, cuticular liposoluble extracts were obtained from following samples adult females be used as experimental treatments: (1) ventral exoskeleton immature (VI), (2) dorsolateral (DI), (3) mature (VM), and (4) (DM). Polyvinyl chloride tubes (artificial females; AF) coated with each extract behavior displayed by sexually males AF was recorded classified follows: 0 = no response; 1 contact; 2 pushing; 3 prolonged (≥10 s). test hypothesis that collected portion abdomen have a higher effect on than exoskeleton, experiment divided into two bioassays: Bioassay I (VI vs. DI) II (VM DM). In bioassay, all treatments significantly different (p > 0.05) CTL group (AF hexane). Notably, pushing < VI treatment compared DI treatment. These results provide sexual recognition function located primarily vannamei.

Published: Jan. 1, 2025

ABSTRACT Spawning, settlement, and metamorphosis represent the most challenging events for hatchery bivalve production. To enhance aquaculture, hatcheries have relied on a range of chemical compounds to induce these biological processes. Yet, despite apparent importance cues, there is little knowledge chemosensory systems role communication in bivalves.

Ocean acidification does not overlook sex: Review of understudied effects and implications of low pH on marine invertebrate sexual reproduction

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Sexual reproduction is a fundamental process essential for species persistence, evolution, and diversity. However, unprecedented oceanographic shifts due to climate change can impact physiological processes, with important implications sexual reproduction. Identifying bottlenecks vulnerable stages in reproductive cycles will enable better prediction of the organism, population, community, global-level consequences ocean change. This article reviews how acidification impacts processes marine invertebrates highlights current research gaps. We focus on five economically ecologically taxonomic groups: cnidarians, crustaceans, echinoderms, molluscs ascidians. discuss spatial temporal variability experimental designs, identify trends performance acidified conditions context early traits (gametogenesis, fertilization, resource allocation), provide quantitative meta-analysis published literature assess effects low pH fertilization rates across taxa.

Published: March 12, 2024

Finding a mate is of the utmost importance for organisms, and traits associated with successfully finding one can be under strong selective pressures. In habitats where biomass population density often low, like enormous open spaces deep sea, animals have evolved many adaptations mates. One convergent adaptation seen in deep-sea fishes sexual dimorphism olfactory organs, where, relative to body size, males greatly enlarged organs compared females. Females are known give off chemical cues such as pheromones, these stimuli traverse long distances stable, stratified water sea picked up by males. This believed help multiple lineages find mates habitats. this study, we describe first morphological evidence lanternfishes (Myctophidae) genus Loweina . Lanternfishes most abundant vertebrates hypothesized use visual signals from bioluminescence recognition or detection.
