  abstract = {1. {M}arine ecosystem models have been used to project the impacts of climate-induced changes in temperature and oxygen on biodiversity mainly through changes in species spatial distributions and primary production. {H}owever, fish populations may also respond to climatic pressures via physiological changes, leading to modifications in their life history that could either mitigate or worsen the consequences of climate change.2. {B}uilding on the individual-based multispecies ecosystem model {OSMOSE}, {B}ioen-{OSMOSE} has been developed to account for high trophic levels' physiological responses to temperature and oxygen in future climate projections. {T}his paper presents an overview of the {B}ioen-{OSMOSE} model, mainly detailing the new developments. {T}hese consist in the implementation of a bioenergetic sub-model that mechanistically describes somatic growth, sexual maturation and reproduction as they emerge from the energy fluxes sustained by food intake under the hypotheses of a biphasic growth model and plastic maturation age and size represented by a maturation reaction norm. {T}hese fluxes depend on temperature and oxygen concentration, thus allowing plastic physiological responses to climate change.3. {T}o illustrate the capabilities of {B}ioen-{OSMOSE} to represent realistic ecosystem dynamics, the model is applied to the {N}orth {S}ea ecosystem. {T}he model outputs are confronted with population biomass, catch, maturity ogive, mean size-at-age and diet data of each species of the fish community. {T}he model succeeds in reproducing observations, with good performances for all indicators. {A} first exploration of current spatial variability in species' bioenergetic fluxes resulting from temperature, oxygen, and food availability is presented in this paper, highlighting the role of temperature.4. {T}his new model development opens the scope for new fields of research such as the exploration of seasonal or spatial variation in life history in response to biotic and abiotic factors at the individual, population and community levels. {U}nderstanding such variability is crucial to improve our knowledge on potential climate change impacts on marine ecosystems and to make more reliable projections under climate change scenarios.},
