Temperature and heart rate as stress indicators of handled common eider

摘要: Three eider ducks were handled every 4 min for 16 to measure their cloacal temperature. This simple handling triggered a rise in core temperatures from 41.5+/-0.6 degrees C at minute 0 43.5+/-0.5 16. increase body temperature occurred with no obvious motor load the eiders, but was facilitated by peripheral vasoconstriction and, moreover, blocked significantly salicylate, suggesting that due fever. After 10 days of similar handling, mean fever-like responses displayed lower than day one, showing habituation emotional stimulation. The eider's heart rate measured continuously before, during and 10-min session following 1-min period. Results showed eiders tachycardia 2-3 posthandling. Such is another sign emotion animals [Am J Psychol 39 (1927) 106]. Our study therefore are prone emotions when emotionally stressed, will display response tachycardia. results on obtained studies more terrestrial birds conditions (e.g., chicken [Physiol Behav 69 (2000) 541]), opposition bradycardia observed decreases [Hvalradets Skr 22 (1940) 1; Acta Physiol Scand 46 (1959) 231] forcibly submerged.
