“…Gene expression of TCA genes does not correspond with this pattern, however. Here, the authors conclude expression of the selected genes does not explain the differences in measured behavioral responses and physiological traits [41].…”

“…The authors instead report that maintaining acid-base equilibrium during pCO 2 stress comes at a cost to biomineralization, since these animals show a reduction in net calcification rate [50]. In burrowing razor clams, Sinonovacula constricta, the depth at which clams burrow decreases with increasing pCO 2 (549-3064 μatm) which is associated with decreases in oxygen consumption rates and Ca 2+ /Mg 2+ ATPase activity [41]. Gene expression of TCA genes does not correspond with this pattern, however.…”

“…While studies have investigated metabolic rates and ATP production in response to pH [98], gene expression has become another tool to assess the potential for metabolic depression, especially to elucidate mechanisms of this response (Table 2). Gene expression studies reporting metabolic depression in marine metazoans include adult blue mussels [45], adult pearl oysters [50,51], purple sea urchin larvae [81,82], temperate brittle stars [72], clams [41], Arctic copepods [66], developing Medaka fish [93], marine polychaetes [37] and reef-building corals [21,[24][25][26]. Despite being commonly observed across gene expression studies in response to low pH, the means by which metabolic depression is characterized through gene expression data varies by study and taxon.…”

Ocean acidification promotes broad transcriptomic responses in marine metazoans: a literature survey

2020

For nearly a decade, the metazoan-focused research community has explored the impacts of ocean acidification (OA) on marine animals, noting that changes in ocean chemistry can impact calcification, metabolism, acid-base regulation, stress response and behavior in organisms that hold high ecological and economic value. Because OA interacts with several key physiological processes in marine organisms, transcriptomics has become a widely-used method to characterize whole organism responses on a molecular level as well as inform mechanisms that explain changes in phenotypes observed in response to OA. In the past decade, there has been a notable rise in studies that examine transcriptomic responses to OA in marine metazoans, and here we attempt to summarize key findings across these studies. We find that organisms vary dramatically in their transcriptomic responses to pH although common patterns are often observed, including shifts in acid-base ion regulation, metabolic processes, calcification and stress response mechanisms. We also see a rise in transcriptomic studies examining organismal response to OA in a multi-stressor context, often reporting synergistic effects of OA and temperature. In addition, there is an increase in studies that use transcriptomics to examine the evolutionary potential of organisms to adapt to OA conditions in the future through population and transgenerational experiments. Overall, the literature reveals complex organismal responses to OA, in which some organisms will face more dramatic consequences than others. This will have wide-reaching impacts on ocean communities and ecosystems as a whole.

“…The current surface seawater pH is approximately 8.1-8.2 and is predicted to decrease to 7.7-7.8 by 2100 and 7.3-7.4 by 2300 [4,5]. OA can affect the fertilization [6], embryonic development, metabolism [7], behavior [8][9][10], and immunity [11] of various marine organisms; threatens the survival and reproduction of marine animals; and damages global marine biodiversity and ecosystem stability [12][13][14][15]. Acidification negatively affects the early developmental stage of abalones Haliotis diversicolor and significantly reduces the survival rate of larvae [16].…”

Combined effects of ocean acidification and hypoxia on the early development of the thick shell mussel Mytilus coruscus

Ocean acidification has become serious, and seawater hypoxia has become evident in acidified waters. The combination of such stressors may have interactive effects on the fitness of marine organisms. In order to investigate the interactive effects of seawater acidification and hypoxia on the early development of marine bivalves, the eggs and sperm of the thick shell mussel Mytilus coruscus were exposed to combined treatments of pH (8.1, 7.7, 7.3) and dissolved oxygen (2, 6 mg/L) for 96 h culture observation to investigate the interactive effects of seawater acidification and hypoxia on the early development of marine bivalves. Results showed that acidification and hypoxia had significant negative effects on various parameters of the early development of the thick shell mussel. However, hypoxia had no effect on fertilization rate. Significant interactions between acidification and hypoxia were observed during the experiment. Short-term exposure negatively influenced the early development of the thick shell mussel but did not affect its survival. The effects of long-term exposure to these two environmental stresses need further study.

“…Mussels (Mytilus spp., Linnaeus, 1758) have been a widely used indicator species (Beyer et al, 2017), but there are other bivalve candidates, including the razor clam. The use of razor clams as sentinels has been evaluated in China, using the Chinese razor clam, Sinonovacula constricta (Lamarck, 1818), an important aquaculture species (Peng et al, 2017). The Pacific razor clam, Siliqua patula (Dixon, 1789), may have merit as a bioindicator species in the northeast Pacific as it is important ecologically and economically (Bishop & Powers, 2003;Saeedi & Costello, 2019).…”

An emerging approach to ecosystem monitoring involves the use of physiological biomarker analyses in combination with gene transcription assays. For the first time, we employed these tools to evaluate the Pacific razor clam (Siliqua patula), which is important both economically and ecologically, as a bioindicator species in the northeast Pacific. Our objectives were to (1) develop biomarker and gene transcription assays with which to monitor the health of the Pacific razor clam, (2) acquire baseline biomarker and gene transcription reference ranges for razor clams, (3) assess the relationship between physiological and gene transcription assays and (4) determine if site-level differences were present. Pacific razor clams were collected in July 2015 and 2016 at three sites within each of two national parks in southcentral Alaska. In addition to determining reference ranges, we found differences in biomarker assay and gene transcription results between parks and sites which indicate variation in both large-scale and local environmental conditions. Our intent is to employ these methods to evaluate Pacific razor clams as a bioindicator of nearshore ecosystem health. Links between the results of the biomarker and gene transcription assays were observed that support the applicability of both assays in ecosystem monitoring. However, we recognize the need for controlled studies to examine the range of responses in physiology and gene transcripts to different stressors.
