Vasomotor responses of trout coronary arterioles to increasing concentrations of adenosine (ADE) (A) and serotonin (SER) (B) at three acclimation temperatures (1°C, 5°C, and 10°C). Dissimilar lower-case letters indicate significant differences in the response of vessels to the various concentrations of ADE or SER at a given acclimation temperature. Dissimilar capital letters indicate significant differences in the response of vessels at different acclimation temperatures to the same concentration of ADE or SER. To improve clarity of the figure, capital letters are not included when differences were not significant (i.e., AAA). P < 0.05, except where indicated (*), where 0.1 > P ≥ 0.05. Note: a series of sham saline injections did not result in noticeable (i.e., <0.6%) changes in vessel ID. Thus we considered any change in vessel ID greater than the mean change + 2 SD caused by the sham saline injections (∼3%) to be biologically significant.
