“…pH had no additional effect on SMR alongside elevated temperature. Similar results have been found in M. edulis, where temperature is the dominant factor in influencing SMR and addition of low pH stress does not affect the SMR response (Lemasson et al, 2018;Matoo et al, 2021). However, the increased SMR of M. edulis in response to OA at 15 °C is not well documented.…”

“…Interestingly, shell shape or shell thickness do not appear to be influenced by temperature. Studies on European mussels document the influence of increased temperature on growth, which includes increased mortality [ 5 ], increased metabolic rate [ 39 ], increased crystal disorder [ 40 ], as well as combined with salinity changes decreasing shape heterogeneity and increasing shell thickness [ 28 , 41 ]. The lack of variation in shell shape and thickness between early historical and modern material and between modern locations, in our results, suggests the mussels on the east coast of the US do not respond to temperature and salinity in the same way as European mussels.…”

Mytilus edulis is a commercially and ecologically important species found along the east coast of the United States. Ecologically, M. edulis improves water quality through filtration feeding and provides habitat formation and coastal protection through reef formation. Like many marine calcifiers, ocean warming, and acidification are a growing threat to these organisms—impacting their morphology and function. Museum collections are useful in assessing long-term environmental impacts on organisms in a natural multi-stressor environment, where acclimation and adaptation can be considered. Using the American Museum of Natural History collections ranging from the early 1900s until now, we show that shell porosity changes through time. Shells collected today are significantly more porous than shells collected in the 1960s and, at some sites, than shells collected from the early 1900s. The disparity between porosity changes matches well with the warming that occurred over the last 130 years in the north Atlantic suggesting that warming is causing porosity changes. However, more work is required to discern local environmental impacts and to fully identify porosity drivers. Since, porosity is known to affect structural integrity, porosity increasing through time could have negative consequences for mussel reef structural integrity and hence habitat formation and storm defenses.

“…The combination of both factors has recently been reviewed (Baag and Mandal, 2022) and literature shows that ocean warming is the main driver affecting an organism's metabolism while the effects of acidification play more of an additive role (e.g. Pinsky et al, 2019;Matoo et al, 2021).…”

Recently, we could show that scallops show limitations of muscular performance like a reduced force under ocean warming and acidification. However, the underlying mechanisms at the cellular level are not completely understood. Metabolomics has become a valuable tool to evaluate the responses of marine organisms to various stressors. In the present study we therefore used a semi-targeted, multi tissue NMR based metabolomic approach to analyze metabolite patterns in the Atlantic king scallop, Pecten maximus, that were long-term acclimated to different end of century conditions of ocean warming (OW), ocean acidification (OA) and their combination (OWA). We investigated tissue specific metabolic profiles and metabolite concentrations in frozen tissues from gills, mantle and phasic and tonic adductor muscle of P. maximus under present conditions using 1H-HR-MAS NMR spectroscopy. A set of 33 metabolites revealed a clear tissue-specific pattern which can be attributed to the individual functions of the respective tissue type. We then evaluated the impact of OW, OA and OWA on the metabolic profiles of the different tissues. OW was the main driver of the changes in metabolites. In particular, energy-related metabolites seem to play an important role in the physiological response of scallops to OW and OWA. In combination with pathway analysis and network exploration we propose a possible correlation between metabolic changes in the adductor muscle and limited swimming performance of P. maximus under future climate. While the metabolic response of the phasic muscle seems to mainly depend on net consumption of energy related metabolites such as ATP and phospho-L-arginine, the tonic muscle seems to rely on metabolizing specific amino acids and beta-oxidation to account for the elevated energetic requirements under ocean warming and acidification.
