“…(2011) observed a potential transgenerational plasticity to buffer the acidification influence, suggesting that larvae originating from pre‐exposed adults to lower pH (7.8) were more resilient to future OA. By contrast, additive negative effects of 2‐month parental exposure to low pH (7.7) were found on larval survival (Marčeta et al., 2022). Because sea urchins tested in Moulin et al.…”

“…(2021), who established a general tolerance threshold in echinoderms between 7.60 and 7.75, above which impaired physiological responses appear. Water acidification has a significant impact on the body development of both larval and juvenile forms, altering their morphology and metabolism, with subsequent severe consequences on individual fitness (Gaitan‐Espita et al., 2017; Li et al., 2020; Mačeta et al., 2022; Stumpp et al., 2011; Zhan et al., 2016; Table 1). Nonetheless, the OA threshold of sea urchins is habitat dependent, indicating that acclimatisation and adaptation processes can shape the individual's sensitivity to lower pH at local scale (Gaitan‐Espita et al., 2017; Kapsenberg et al., 2017).…”

Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial to anticipate challenges that are resulting from the current environmental alterations. In this review, we rely on the estimated physiological limits of six commercialised species of sea urchins (Loxechinus albus, Mesocentrotus franciscanus, Paracentrotus lividus, Strongylocentrotus droebachiensis, Strongylocentrotus intermedius and Strongylocentrotus purpuratus) to define the vulnerability (or resilience) of their populations facing ocean warming and acidification (OW&A). Considering that coastal systems do not change uniformly and that the populations’ response to stressors varies depending on their origin, we investigate the effects of OW&A by including studies that estimate future environmental mutations within their distribution areas. Cross‐referencing 79 studies, we find that several sea urchin populations are potentially vulnerable to the predicted OW&A as environmental conditions in certain regions are expected to shift beyond their estimated physiological limit of tolerance. Specifically, while upper thermal thresholds seem to be respected for L. albus along the SW American coast, M. franciscanus and S. purpuratus southern populations appear to be vulnerable in NW America. Moreover, as a result of the strong warming expected in the Arctic and sub‐Arctic regions, the local productivity of S. droebachiensis is also potentially largely affected. Finally, populations of S. intermedius and P. lividus found in northern Japan and eastern Mediterranean respectively, are supposed to decline due to large environmental changes brought about by OW&A. This review highlights the status and the potential of local adaptation of a number of sea urchin populations in response to changing environmental conditions, revealing possible future challenges for various local fishing industries.

“…lack of monophyly for the stony corals), demonstrating a possibly ancient origin for sAC in this phylum, which supports a conserved role for sAC in foundational biological processes such as sexual reproduction. Given that the activation of the sAC-cAMP-PKA pathway is stimulated by alkalinization of the sperm cytosol, this result also has important implications for the reproduction of broadcast spawning marine invertebrates in the face of anthropogenic ocean acidification, which is already known to alter sperm motility in many species after exposure of either sperm or adult males prior to spawning [6,[54][55][56][57][58][59]. Future work should investigate the role of sAC-cAMP-PKA signalling in sperm from a broader diversity of species to clarify the mechanisms by which ocean acidification might impact reproduction across invertebrate phyla in future seas.…”

Most stony corals liberate their gametes into the water column via broadcast spawning, where fertilization hinges upon the activation of directional sperm motility. Sperm from gonochoric and hermaphroditic corals display distinct morphological and molecular phenotypes, yet it is unknown whether the signalling pathways controlling sperm motility are also distinct between these sexual systems. Here, we addressed this knowledge gap using the gonochoric, broadcast spawning coral Astrangia poculata . We found that cytosolic alkalinization of sperm activates the pH-sensing enzyme soluble adenylyl cyclase (sAC), which is required for motility. Additionally, we demonstrate for the first time in any cnidarian that sAC activity leads to protein kinase A (PKA) activation, and that PKA activity contributes to sperm motility activation. Ultrastructures of A. poculata sperm displayed morphological homology with other gonochoric cnidarians, and sAC exhibited broad structural and functional conservation across this phylum. These results indicate a conserved role for pH-dependent sAC-cAMP-PKA signalling in sperm motility across coral sexual systems, and suggest that the role of this pathway in sperm motility may be ancestral in metazoans. Finally, the dynamics of this pH-sensitive pathway may play a critical role in determining the sensitivity of marine invertebrate reproduction to anthropogenic ocean acidification.

“…A large majority of studies reports detrimental effects of OA on sperm quality, including impairment of the polyspermy block (Reuter et al, 2011;Bögner et al, 2014), as well as a reduction of sperm velocity, motility and viability (Havenhand et al, 2008;Schlegel et al, 2012;Campbell et al, 2016). Contrasting speciesspecific differences in OA impact have also shown both positive and absence of effect on sperm quality (Havenhand and Schlegel, 2009;Caldwell et al, 2011;Marcěta et al, 2022). Under stressful conditions sperm quality can be also highly variable among individuals, with both improving and impairing intra-specific effects of OA (Gallo et al, 2020b).…”

IntroductionDue to their relevant ecological position and well-studied biology, sea urchins are reference organisms for ocean acidification studies, at both within- and trans-generational levels. In this study, we examined gamete quality in specimens exposed to future predicted (-0.4 units) pH conditions during gametogenesis.MethodsEgg physical characteristics, biochemical composition, and fatty acid profiles were assessed after two and six months of exposure, while sperm viability and velocity were analyzed after six months of exposure. Considering the documented intraspecific variability in response to ocean acidification, this study involved two populations of Paracentrotus lividus. One population was sampled from the highly variable lagoon of Venice (Site 1), while the other was obtained from a coastal area (Site 2) characterized by more stable environmental conditions and facing minimal anthropogenic stress.ResultsA different response was highlighted in the two sites. Noteworthy trends emerged, especially in the fatty acid profile and sperm traits. Although adults were fed the same diet, Site 1 eggs contained more high-energetic fatty acids than Site 2, potentially boosting the survival odds for the next generation. Moreover, Site 1 sperms displayed higher viability but slower motility compared to those from Site 2. Within sites, a significant difference between time points and a change in the fitness strategy of sea urchin females emerged when comparing eggs spawned after two and six months of exposure to reduced pH. The effects of time and exposure pH are more pronounced in animals from Site 1, suggesting a higher adaptability of this population rather than negative effects of ocean acidification.DiscussionOverall, our findings suggest that sea urchins have the potential to acclimate to reduced pH and to produce gametes of the same quality as controls held at the currently natural pH. Our findings emphasize the relevance of combining investigations of gamete quality characteristics, particularly egg biochemistry and fatty acid composition, and considering site variability to fully understand the transgenerational response potential of sea urchins to ocean acidification.
