“…< 25%). Yuan et al (2018) found reduced settlement in A. gemmifera larvae when exposed to reduced pH NBS (7.8 and 7.5) at the time of settlement. In echinoderms, Dupont et al (2013) noted delayed settlement in S. droebachiensis, while in the sea urchin Paracentrotus lividus, García et al (2015) observed delayed settlement by 8 d in pH NBS 7.7 compared to pH NBS 8.1, and no settlement at pH NBS 7.4.…”

“…The juveniles generated in OA conditions were smaller than the controls (Wangensteen et al 2013). In corals, Yuan et al (2018) observed reduced percentage settlement of Acropora gemmifera larvae that had been cultured at 3 concentrations of CO 2 (corresponding to pH NBS 8.1, 7.8 and 7.5). After settlement, the recruits showed decreased calcification and growth, changes consistent with the downregulation of calcification-related genes.…”

Most marine organisms present an indirect lifecycle where a planktonic larval stage reaches competency before settling to the substrate and metamorphosing. Despite the critical importance of these early life history stages, little is known about how global change-related stressors, in particular ocean acidification (OA), affect marine larval settlement and metamorphosis. To date, 48 studies have investigated the effects of OA on larval settlement, focussing mostly on tropical corals (16), echinoderms (11) and fish (8). Most studies show negative effects of OA during settlement and post-settlement processes. For instance, reduced settlement is typically seen along natural pH gradients and in experimentally lowered pH treatments. This generally results in reduced settlement selectivity and metamorphosis and poorer post-settlement fitness. Carryover effects of OA exposure can also occur, with larval environmental history influencing early post-settlement performance. We conclude that OA may (1) alter larval supply for settlement by altering horizontal swimming behaviour or vertical migration; (2) directly influence settlement success through changes in the nature and distribution of suitable settlement substrates (e.g. biofilm, crustose coralline algae); and (3) mediate carryover effects at settlement by altering larval development or larval energy budgets. In contrast to fish larvae, there is little evidence for most invertebrate larvae that their perception of settlement cues is directly influenced by reduced pH. A summation of how OA affects the settlement and metamorphosis of marine invertebrates is timely, since altered settlement rates will influence the future distributions, abundances and ecology of marine benthic communities.

The increased energetic costs of maintaining homeostatic processes under disrupted acid-base balances and ionic gradients can additionally slow development and reduce growth of marine invertebrate larvae and recruits (Albright and Langdon, 2011;Byrne, 2012;Przeslawski et al, 2015;Timmins-Schiffman et al, 2013).…”

In light of the chronic stress and mass mortality reef-building corals face under climate change, it is critical to understand the processes essential to reef persistence and replenishment, including coral reproduction and development. Here we quantify gene expression and size sensitivity to ocean acidification across a set of developmental stages in the rice coral, Montipora capitata. Gametes and then embryos and swimming larvae were exposed to three pH treatments ranging from 7.8 (Ambient), 7.6 (Low) and 7.3 (Xlow) from fertilization to 9 days post-fertilization. Embryo development and size, planula volume, and stage-specific gene expression were compared between treatments at each stage to determine the effects of acidified seawater on early development. While there was no measurable size differentiation between fertilized eggs and embryos at the prawn chip stage exposed to ambient, low, and extreme low pH, early gastrula and planula raised in reduced pH treatments were significantly smaller than those raised in ambient seawater, suggesting an energetic cost to developing under low pH. However, no differentially expressed genes emerged between treatments at any time point, except swimming larvae. Larvae from pH 7.6 showed upregulation of genes involved in cell division, regulation of transcription, lipid metabolism, and oxidative stress in comparison to the other two treatments, and smallest sizes in this treatment. While low pH appears to increase energetic demands and trigger oxidative stress, the developmental process is robust to this at a molecular level, with swimming larval stage reached in all pH treatments.

“…Research has continued to focus on mollusks, arthropods and echinoderms, however, cnidarian settlement and metamorphosis (Foster et al, 2015;Olsen et al, 2015;Viyakarn et al, 2015;Fabricius et al, 2017;Yuan et al, 2018), the settlement behavior and swimming activity of a bryozoan (Pecquet et al, 2017), and settlement of an annelid (Nelson et al, 2020) have also been studied. In addition to continuing to assess the impact of elevated CO 2 on the range of behaviors previously studied (above), a few new behaviors have also been investigated.…”
