Increasing variation in ocean temperature may affect the metabolism and energetic demands of many species. Understanding such effects is particularly important for sedentary species that cannot make large-scale movements in response to changes in environmental conditions. I examined how metabolic rates responded to temperature in the bluebanded goby (Lythrypnus dalli) and the Woolly Sculpin (Clinocottus analis). Oxygen consumption and metabolic rate increased significantly with temperature for both species, but L. dalli was much more sensitive to the effects of temperature than C. analis (Q 10 values were 5.21 and 3.02, respectively). Thermal fluctuations likely play a significant role in the ecology of these species and continued increases in seawater temperature will either necessitate an increase in foraging and food consumption or drive costly trade-offs between metabolism and processes such as growth and reproduction.
