Metabolomic and phenotypic effects of ocean acidification on cuttlefish differ across early life stages.

Marine Environmental Research, Год журнала: 2025, Номер 205, С. 107013 - 107013

Ocean acidification (OA) affects the physiology and behaviour of some marine organisms, impacting their development metabolism during vulnerable early-life stages. Among them, embryo cuttlefish develops for about two months in encapsulated eggs with harsh perivitelline conditions hypoxia hypercapnia, potentially worsened by OA. In this study, common Sepia officinalis embryos juveniles, were exposed to five pH (pHT 8.08 7.43). Growth, metabolite profiles explored embryonic period up 10 days-post-hatching. Our results show delayed decreased hatching success at 7.43, but no effect on juvenile weight upon hatching. The 1H Nuclear Magnetic Resonance (NMR) spectroscopy revealed that decreasing affected metabolites until a metabolic suppression was observed 7.43. O2 consumption 10d-old juveniles did not change whereas indicated switch anaerobic under low pH. Overall, our suggest transition from stage free life shapes metabolomic reprogramming more drastically than ocean acidification.

Synthesis of Thresholds of Ocean Acidification Impacts on Decapods

Frontiers in Marine Science, Год журнала: 2021, Номер 8

Опубликована: Окт. 26, 2021

Assessing decapod sensitivity to regional-scale ocean acidification (OA) conditions is limited because of a fragmented understanding the thresholds at which they exhibit biological response. To address this need, we undertook three-step data synthesis: first, compiled dataset composed 27,000 datapoints from 55 studies responses OA. Second, used statistical threshold analyses identify OA using pH as proxy for 13 response pathways physiology behavior, growth, development and survival. Third, worked with panel experts review these thresholds, considering contributing datasets based on quality study, assign final associated confidence scores consistency findings among studies. The duration-dependent were within range 7.40 7.80, ranging behavioral physiological mortality, many being assigned medium-to-high confidence. Organism increased duration exposure but was not linked specific life-stage. that emerge our provide foundation consistent interpretation monitoring or numerical model simulations support climate change marine vulnerability assessments evaluation management strategies.

Effects of temperature increase on the physiology and behavior of fiddler crabs

Physiology & Behavior, Год журнала: 2019, Номер 215, С. 112765 - 112765

Intertidal organisms rely on physiological and behavioral adjustments to maintain homeostasis under warm exposure. We examined the effects of temperature increase related climate warming physiology behavior two fiddler crab species: Leptuca uruguayensis, which inhabits mostly vegetated areas, leptodactyla, that unvegetated areas. hypothesized L. uruguayensis would be more sensitive than leptodactyla. Crabs were exposed different temperatures: 27 °C (control), 31 33 (+4 +6 °C, respectively) for 15 days evaluate their responses (oxygen consumption, Q10, ammonia excretion hepatosomatic index) 2 observe (feeding rate duration burrow retreat). also tested in situ effect air, surface, body temperatures claw-waving display both species. found species affected differently by increasing temperature. showed adaptation limit (Q10 <1), oxygen consumption. Also, comparison with control, decreased at but not indicating a compensatory mechanism cope thermal stress. In contrast, leptodactyla was able adjust its metabolic rise ~3) reduce excretion, suggesting changes energetic substrate amino acid catabolism. Higher index species, increased use energy reserve (although only feeding reduced). Furthermore, warmer retreat potentially impacting social interactions, such as mating. Temperature did affect frequency, other factors may this behavior, e.g., presence females competitors. Specific (e.g., microhabitat selection) morphological attributes larger major claw) might benefit thermoregulation each since no differences between them situ. Therefore, crabs inhabit areas are vulnerable higher change geographic range result warming, while tolerant have competitive advantage scenario.

In this study, we evaluated the growth, osmoregulation and energy metabolism of oriental river prawn, Macrobrachium nipponense, reared during 6 weeks with different salinities (0, 8, 14 22 g/L). The results showed that haemolymph osmolality M. nipponense increased an increase in ambient osmotic pressure; isosmotic point was 490 mOs/kg H2O. prawns a higher survival rate, weight gain rate hepatopancreas index salinity g/L.

Living under natural conditions of ocean acidification entails energy expenditure and oxidative stress in a mussel species

Marine Pollution Bulletin, Год журнала: 2024, Номер 203, С. 116470 - 116470

Опубликована: Май 9, 2024

We investigated the health conditions of Mediterranean mussel Mytilus galloprovincialis recruited in CO2 vents system Castello Aragonese at Ischia Island (Mediterranean Sea). Individuals M. were sampled three sites along pH gradient (8.10, 7.7 and up to <7.4). Untargeted metabolomics biochemical endpoints related energetic metabolism, oxidative stress/damage, neurotoxicity immune defense analyzed. Corrosion valves occurred low pH. A separation metabolome was observed gradient. Metabolites belonging amino acids, nucleosides, lipids organic osmolytes significantly reduced organisms from most acidified sites. The content reactive oxygen species activity glutathione peroxidase compared ambient pH, no damage induced. Overall results suggested presence an energy cost underpinning long-term survival for this species.
