Heart rate, a measure of metabolism in blue-winged teal

Heart rate, a measure of metabolism in blue-winged teal

1. 1. Both existence metabolism ( Y) and heart rate ( HR) varied linearly with temperature, enabling one to formulate an equation for predicting metabolism from heart rate ( Y = 37·35+0·268 HR ± 11·934). 2. 2. In relation to existence metabolism, oxygen pulse decreased with decreasing temperature. 3...

Zusammenfassung:1. 1. Both existence metabolism ( Y) and heart rate ( HR) varied linearly with temperature, enabling one to formulate an equation for predicting metabolism from heart rate ( Y = 37·35+0·268 HR ± 11·934). 2. 2. In relation to existence metabolism, oxygen pulse decreased with decreasing temperature. 3. 3. Heart rates of teal living under semi-controlled free conditions were 52·6±12·6 ( X± S.E.) beats higher than under controlled conditions. This represented a metabolic increase of 14·3 ± 3·4 kcal/bird per day. 4. 4. The ecological implications of this research are discussed.
