Abstract Phenotypic plasticity allows organisms to track changing trait optima under environmental variation. To what extent this is achieved will be jointly determined by the rate of and capacity for plasticity. Despite potential fitness implications these two components phenotypic plasticity, a quantitative understanding their variance across types conditions lacking. Here, we address knowledge gap compiling data from time‐course experiments that describe how range physiological traits aquatic ectotherms changes in response shift salinity. We then build upon recent analytical advances produce estimates each experiment are comparable traits. A total 324 originating 59 species fishes, sharks crustaceans were available analyses. For experiment, was assigned one five categories. Bivariate meta‐analyses used quantify temperature effects on rates capacities Our analyses show plastic responses change salinity differ among categories, interactive effect category differs capacity. Temperature more consistent than capacity, with higher temperatures being associated faster hormones, metabolites metabolic osmoregulatory enzymes. positive only found Within observed temperatures, hormones had consistently fastest predicted salinity, whereas categories enzymes relatively slow comparison. Plastic substantially those previously reported thermal tolerance. study adds growing evidence has important axes Further progress can deal fluctuating environments likely benefit increased theoretical empirical efforts within field research.
