| contents | Temperature-metabolism relationships and the impact of confounding variables: A meta-analysis of mussels, oysters, and clams from the Northwest Atlantic. Clarke, Shelby B Filgueira, Ramón Animals Bivalvia Temperature Atlantic Ocean Ostreidae Basal Metabolism As oceanic temperatures increase with climate change, waters in the Northwest Atlantic are warming at a rate that exceeds global averages, leading to potential consequences for local ectothermic organisms. This region supports 4 species of bivalves of commercial importance: blue mussels (Mytilus edulis), eastern oysters (Crassostrea virginica), hard clams (Mercenaria mercenaria), and soft-shell clams (Mya arenaria). Given their ecological and economic importance, the objective of this study was to investigate the effect of temperature on the metabolic rate (MR) of these species by synthesizing the existing body of literature. A meta-analysis of 101 publications was conducted, where 788 MR values were compiled (585 for mussels, 158 for oysters, 11 for hard clams, and 34 for soft-shell clams) from 12 countries, revealing variation in metabolic performance both within and among species. Given the abundance of data for mussels and oysters, Arrhenius models were developed to describe the relationship between temperature and metabolism. Mussels were observed to have the lowest upper performance limit (∼26 °C), while clams were intermediate, and oysters were highest (∼30-34 °C). In addition, the influence of four confounding factors (ontogenetic stage, metabolic status, habitat, and season) on the MR of mussels and oysters was quantified using Bayesian approaches. Ontogenetic stage and metabolic status were observed to have similar effects on the MR of both species, while the effects of habitat and season on MR differed between species. The findings of this study suggest that temperature is one of the important drivers of MR in bivalves, while also offering insight to influence of endogenous and exogenous variables on their physiological performance. |
