Annual cycles of metabolic rate are genetically determined but can be shifted by phenotypic flexibility.

The Journal of experimental biology - 1 Oct 2012

Versteegh M A, Helm B, Gwinner E, Tieleman B I

Abstract excerpt

Birds have adjusted their life history and physiological traits to the characteristics of the seasonally changing environments they inhabit. Annual cycles in physiology can result from phenotypic flexibility or from variation in its genetic basis. A key physiological trait that shows seasonal variation is basal metabolic rate (BMR). We studied genetic and phenotypic variation in the annual cycles of body mass,...
