  abstract = {{I}ntroduction{O}n-going climate change is now recognized to yield physiological stresses on marine species, with potentially detrimental effects on ecosystems. {H}ere, we evaluate the prospect of using climate velocities ({CV}) of the metabolic index (phi) for assessing changes in habitat in the {S}outh {E}ast {P}acific. {M}ethods{O}ur approach is based on a species with mean ecophysiotype (i.e. model species) and the use of a global {E}arth {S}ystem {M}odel simulation ({CESM}-{LE}) under {RCP} 8.5 scenario. {T}he {SEP} is chosen as a case study as it hosts an {O}xygen {M}inimum {Z}one and seamounts systems sustaining local communities through artisanal fisheries. {R}esults and {D}iscussion{O}ur results indicate that {CV} phi pattern is mainly constrained by the oxygen distribution and that its sign is affected by contrasting oxygen trends (including a re-oxygenation in the upper {OMZ}) and warming. {W}e further show that {CV} phi is weakly dependent on physiological traits composing phi, which conveys to this metrics some value for inferring the projected mean displacement and potential changes in viability of metabolic habitat in a region where physiological data are scarce. {B}ased on sensitivity experiments to physiological traits and natural variability, we propose a general method for inferring broad areas of climate change exposure regardless of species-specific phi. {W}e show in particular that for the model used here, the upper {OMZ} region can be considered a "safe" area for the species with ecophysiotype close to that of 71 species used to derive the model species. {L}imitations of the approach and perspectives of this work are also discussed.},
