Abstract Although cross generation (CGP) and multigenerational (MGP) plasticity have been identified as mechanisms of acclimation to global change, the weight evidence indicates that parental conditioning over generations is not a panacea rescue stress sensitivity in offspring. For many species, there were no benefits conditioning. Even when improved performance was observed, this waned time within or across fitness declined. CGP MGP studies resilient species with tolerant genotypes wild populations selected family lines. Several bivalves possess favourable tolerance phenotypically plastic traits potentially associated genetic adaptation life habitats where they routinely experience temperature and/or acidification stress.

Abstract The plea for using more “realistic,” community‐level, investigations to assess the ecological impacts of global change has recently intensified. Such experiments are typically complex, longer, expensive, and harder interpret than simple organism‐level benchtop experiments. Are they worth extra effort? Using outdoor mesocosms, we investigated effects ocean warming (OW) acidification (OA), their combination (OAW), natural fluctuations on coastal communities western Baltic Sea during all four seasons. These dominated by perennial canopy‐forming macrophyte Fucus vesiculosus —an important ecosystem engineer Baltic‐wide. We, additionally, assessed direct response organisms temperature pH in experiments, examined how well responses can predict community‐level dominant driver, OW. OW affected mesocosm substantially stronger acidification. provoked structural functional shifts community that differed strength direction among matched a given species only under warm cold thermal stress, is, summer winter. In other seasons, biotic interactions masked effects. OW‐driven is likely jeopardize future habitat‐forming macroalga F. Sea. Furthermore, conclude seasonal essential our understanding impact because take into account abiotic pressures.

Hypoxia threatens coral and sea anemone early life stages

Limnology and Oceanography, Год журнала: 2025, Номер unknown

Abstract Seawater hypoxia is increasing globally and can drive declines in organismal performance across a wide range of marine taxa. However, the effects on early life stages (e.g., larvae juveniles) are largely unknown, it unclear how evolutionary histories may influence these outcomes. Here, we addressed this question by comparing responses three cnidarian species representing histories: reef‐building coral Galaxea fascicularis , broadcast spawner with horizontal transmission endosymbiotic algae (family Symbiodiniaceae); Porites astreoides brooder vertical endosymbiont transmission; estuarine sea anemone Nematostella vectensis non‐symbiotic spawner. Transient exposure to (dissolved oxygen < 2 mg L −1 for 6 h) led decreased larval swimming growth all species, which resulted impaired settlement corals. Coral‐specific also included swelling, depressed respiration rates, decreases symbiont densities function. These results indicate both immediate latent negative physiology coral–algal mutualisms specifically. In addition, G. P. were sensitized heat stress following exposure, suggesting that combinatorial nature climate stressors will lead declining sensitization was not observed N. exposed hypoxia, be more resilient combined stressors. Overall, emphasize importance reducing anthropogenic carbon emissions limit further ocean deoxygenation warming.

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

Frontiers in Marine Science, Год журнала: 2022, Номер 9

Опубликована: Окт. 28, 2022

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. A total 129 studies investigated 122 selected The dependent taxa, specific examined, study location. Our reveals that rate decreases as decreases, but are taxa-specific. Echinoderm appears more sensitive than changes, while data limited, cnidarians may be most sensitive. Studies echinoderms bivalve prevalent, crustaceans cephalopods among least studied even though they constitute some largest fisheries worldwide. lack information has commercial aquaculture, wild fisheries, conservation restoration populations. recommend expose organisms different levels during entire gametogenic cycle, not only final before gametes or larvae released. argue increased associated molecular mechanisms chemistry. recommendations future allow understanding affected rapidly changing environment.

Kelp forests of the California Current System have experienced prolonged marine heatwave (MHW) events that overlap in time with phenology life history (e.g., gametogenesis and spawning) many benthic invertebrates. To study effect thermal stress from MHWs during purple sea urchin ( Strongylocentrotus purpuratus ) further, whether might induce transgenerational plasticity (TGP) tolerance progeny, adult urchins were acclimated to two conditions laboratory – a MHW temperature 18°C non-MHW 13°C. Following four-month long acclimation period (October–January), adults spawned offspring each parental condition reared at (18°C) temperatures (13°C), creating total four embryo treatment groups. assess effects for groups, we measured hatched blastula embryos acute trials. Embryos MHW-acclimated females more thermally tolerant higher LT 50 values as compared progeny non-MHW-acclimated females. Additionally, there was an female state on body size stages embryonic development - early gastrulae prism, stage echinopluteus larvae. maternal provisioning means also alter performance, assessed gamete traits differentially females, by measuring biochemical composition eggs. had eggs protein concentrations, while egg lipid content showed no differences. Our results indicate TGP plays role altering performance function female, especially when coincides gametogenesis. In addition, data show experience can influence via content. Although this is laboratory-based study, suggest may play resistance S. natural kelp forest setting.
