Reproductive Energy Expenditure, Intraspecific Variation and Fitness in Birds

Part of the Current Ornithology book series (CUOR, volume 16)


Energy is a universal resource widely assumed to play a crucial role in determining reproductive success and survival in all organisms (Carey, 1996; Walsberg, 1983;King, 1974; Cody, 1966). It is also generally believed that high energy demands constrain reproduction through limited availability of energy during single breeding attempts, or through negative effects on future reproduction ( Tinbergen and Dietz, 1994, and references therein; Meijer et al., 1989;Drent and Daan, 1980). Recent reviews of avian energetics (e.g., Carey, 1996) and numerous papers have dealt with patterns of interspecific variation in energy expenditure in relation to different behavioral or life history traits (e.g., Nagy et al., 1999; Bryant, 1997; Ricklefs, 1996; Koteja, 1991; Bennett and Harvey, 1987). These studies have focused on: (1) the existence of some absolute maximum sustainable metabolic rate (MR); (2) scaling of MR and body mass; or (3) the relationship between daily energy expenditure (DEE)
