摘要：

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+0·268HR ± 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. © 1969.
