Climate change exposes benthic species populations in coastal ecosystems to a combination of different stressors (e.g., warming, acidification and eutrophication), threatening the sustainability of the ecological functions they provide. Thermal stress appears to be one of the strongest drivers impacting marine ecosystems, acting across a wide range of scales, from individual metabolic performances to geographic distribution of populations. Accounting for and integrating the response of species functional traits to thermal stress is therefore a necessary step in predicting how populations will respond to the warming expected in coming decades. Here, we developed an individual-based population model using a mechanistic formulation of metabolic processes within the framework of the dynamic energy budget theory. Through a large number of simulations, we assessed the sensitivity of population growth potential to thermal stress and food conditions based on a climate projection scenario (Representative Concentration Pathway; RCP8.5: no reduction of greenhouse gas emissions). We focused on three bivalve species with contrasting thermal tolerance ranges and distinct distribution ranges along 5,000 km of coastline in the NE Atlantic: the Pacific oyster (Magallana gigas), and two mussel species: Mytilus edulis and Mytilus galloprovincialis. Our results suggest substantial and contrasting changes within species depending on local temperature and food concentration. Reproductive phenology appeared to be a core process driving the responses of the populations, and these patterns were closely related to species thermal tolerances. The nonlinear relationship we found between individual life-history traits and response at the population level emphasizes the need to consider the interactions resulting from upscaling across different levels of biological organisation. These results underline the importance of a process-based understanding of benthic population response to seawater warming, which will be necessary for forward planning of resource management and strategies for conservation and adaptation to environmental changes.

“…Downstream effects of temperature changes on these species have the potential to impact distribution, performance, and phenology (Zippay and Helmuth, 2012;Shelmerdine et al, 2017). In this study, a high resolution climate model was coupled to bioenergetic models of C. virginica and M. edulis to explore the differential effects of predicted SST changes on these commercial species in the coming decades.…”

“…Warming ocean temperatures and the expanded northward distribution of the oyster Crassostrea gigas has been extensively studied in European waters (Laugen et al, 2015;Shelmerdine et al, 2017). Spawn dates were estimated in this study using a combination threshold of both temperature and GSI, a common method to trigger spawning in DEB modeling (e.g., Bourlès et al, 2009).…”

“…Temperature plays an important role in physiology, gene expression, distribution, and fitness of bivalves (Zippay and Helmuth, 2012;Shelmerdine et al, 2017). The internal body temperature of bivalves usually matches external water temperatures, except when intertidal species are subject to aerial exposure (Zippay and Helmuth, 2012).…”

“…Although temperature will not be the only change to impact bivalves, it has been shown to be the most deterministic factor influencing shellfish growth and distribution, and is one of the most widely studied abiotic factors related to climate change (Zippay and Helmuth, 2012;Rodrigues et al, 2015;Buckley and Huey, 2016;Filgueira et al, 2016). Warming oceans are modifying current natural ranges of many marine species (e.g., Diederich et al, 2005;Jones et al, 2009Jones et al, , 2010Rinde et al, 2016;Shelmerdine et al, 2017). Despite inherent uncertainty, modeling techniques which incorporate both climate data and organismal bioenergetics are the only tools available to explore the effects of future climate change scenarios on animal populations.…”

Past, Present, and Future: Performance of Two Bivalve Species Under Changing Environmental Conditions

Globally, the production of marine bivalves has been steadily increasing over the past several decades. As the effects of human population growth are magnified, bivalves help provide food security as a source of inexpensive protein. However, as climate change alters sea surface temperatures (SST), the physiology, and thus the survival, growth, and distribution of bivalves are being altered. Challenges with managing bivalves may become more pronounced, as the uncertainty associated with climate change makes it difficult to predict future production levels. Modeling techniques, applied to both climate change and bivalve bioenergetics, can be used to predict and explore the impacts of changing ocean temperatures on bivalve physiology, and concomitantly on aquaculture production. This study coupled a previously established high resolution climate model and two dynamic energy budget models to explore the future growth and distribution of two economically and ecologically important species, the eastern oyster (Crassotrea virginica), and the blue mussel (Mytilus edulis) along the Atlantic coast of Canada. SST was extracted from the climate model and used as a forcing variable in the bioenergetic models. This approach was applied across three discreet time periods: the past (1986)(1987)(1988)(1989)(1990), the present (2016)(2017)(2018)(2019)(2020), and the future (2046-2050), thus permitting a comparison of bivalve performance under different temporal scenarios. Results show that the future growth is variable both spatially and interspecifically. Modeling outcomes suggest that warming ocean temperatures will cause an increase in growth rates of both species as a result of their ectothermic nature. However, as the thermal tolerance of C. virginica is higher than M. edulis, oysters will generally outperform mussels. The predicted effects of temperature on bivalve physiology also provided insight into vulnerabilities (e.g., mortality) under future SST scenarios. Such information is useful for adapting future management strategies for both farmed and wild shellfish. Although this study focused on a geographically specific area, the approach of coupling bioenergetic and climate models is valid for species and environments across the globe.
