“…For example, mussel Musculista senhousia reared at pH 7.7 produces larger eggs, resulting in increased larval growth, survival, metamorphosis, and energy budget of the offspring. [ 138 ] The advantage of parental provisioning is also observed in sea urchin Sterechinus neumayeri after long‐term exposure at pH 7.7. [ 139 ] Transgenerational plasticity can also be mediated by epigenetic inheritance (e.g., DNA methylation), as discussed above (see Section 5.5).…”

CO 2 concentrations surged from ≈280 to ≈400 ppm in the last 250 years. [1] By the end of this century, atmospheric CO 2 concentrations are forecast to range from ≈580 ppm (RCP4.5) to ≈1000 ppm (RCP8.5), depending on the strength of measures taken to mitigate CO 2 emissions. [2,3] The unprecedented upward trend of CO 2 emissions has raised global concern about the future of marine ecosystems because oceans will absorb more atmospheric CO 2 that leads to ensuing pH reduction in seawater (i.e., ocean acidification), [4] following a series of chemical reactions:

“…For the invasive fouling mussel Musculista senhousia , cross generation parental exposure to acidification (pH 7.7) was broadly beneficial for all larval traits investigated (development rate, survival and metamorphosis; Table ). These positive effects were linked to the larger eggs spawned by acidification conditioned females (Zhao et al, ). The positive effects of parental conditioning for progeny continued to the juvenile stage which had higher survival.…”

Although cross generation (CGP) and multigenerational (MGP) plasticity have been identified as mechanisms of acclimation to global change, the weight of evidence indicates that parental conditioning over generations is not a panacea to rescue stress sensitivity in offspring. For many species, there were no benefits of parental conditioning. Even when improved performance was observed, this waned over time within a generation or across generations and fitness declined. CGP and MGP studies identified resilient species with stress tolerant genotypes in wild populations and selected family lines. Several bivalves possess favourable stress tolerance and phenotypically plastic traits potentially associated with genetic adaptation to life in habitats where they routinely experience temperature and/or acidification stress. These traits will be important to help 'climate proof' shellfish ventures. Species that are naturally stress tolerant and those that naturally experience a broad range of environmental conditions are good candidates to provide insights into the physiological and molecular mechanisms involved in CGP and MGP. It is challenging to conduct ecologically relevant global change experiments over the long times commensurate with the pace of changing climate. As a result, many studies present stressors in a shock-type exposure at rates much faster than projected scenarios. With more gradual stressor introduction over longer experimental durations and in context with conditions species are currently acclimatized and/or adapted to, the outcomes for sensitive species might differ. We highlight the importance to understand primordial germ cell development and the timing of gametogenesis with respect to stressor exposure. Although multigenerational exposure to global change stressors currently appears limited as a universal tool to rescue species in the face of changing climate, natural proxies of future conditions (upwelling zones, CO 2 vents, naturally warm habitats) show that phenotypic adjustment and/or beneficial genetic selection is possible for some species, indicating complex plasticity-adaptation interactions.

“…The majority of experimental studies included a relatively short time exposure, which could overestimate effect relative to what occurs in a natural ecological setting (Leuzinger et al, 2011). Many species are able to acclimate (i.e., exhibit phenotypic plasticity) if exposure is sufficiently long (e.g., Dupont et al, 2013;Zhao et al, 2019) and other species show potential for evolutionary adaptation (e.g., Parker et al, 2015;Thor and Dupont, 2015). Most of the studies used in this synthesis do not account for these processes because acclimation studies are difficult to account for in the statistical analyses.…”

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