Table 1:

Direction of change over a 4˚C increase in water temperature for each measured variable for all six species.

Plus sign = significant positive change. Minus sign = significant negative change. Equal sign = no change between Control and Control + 4°C, but significant overall effect of water temperature. NS = no significant effect of water temperature on variable. NA = Not available. SGR = specific growth rate. W-at-L = weight-at-length. CTmax = critical thermal maximum. RMR = Resting metabolic rate. MMR = Maximum metabolic rate. AS = Aerobic scope. FAS = Factorial aerobic scope.
