▪ Abstract We summarize the recent information on field metabolic rates (FMR) of wild
terrestrial vertebrates as determined by the doubly labeled water technique. Allometric …

Publisher Summary The chapter begins with an overview of cost of living based on field
metabolic rates of small mammals. The chapter then goes on to discuss the importance of …

We approach the field of stress immunology from an ecological point of view and ask: why
should a heavy physical workload, for example as a result of a high reproductive effort …

(1) Brood reductions and enlargements were carried out in kestrel nests to evaluate the
consequences of raising different numbers of nestlings for both the offspring and the …

I have chosen to address three major areas in the energetics of free-ranging adult seabirds:
basal metabolism, locomotion, and energy budgets. More information is available on basal …

1. Costs of reproduction have been assessed experimentally by measuring subsequent
survival and reproduction of parent animals raising enlarged and reduced numbers of …

1. Recently, there has been much interest in physiological trade‐offs between parasite
resistance and fitness‐related traits such as secondary sexual characters or reproductive …

We examined the relationship between daily energy expenditure (DEE) and basal metabolic
rate (BMR) in birds and mammals. Two models of the relationship between DEE and BMR …

Measured foraging strategies often cluster around values that maximize the ratio of energy
gained over energy spent while foraging (efficiency), rather than values that would maximize …

We quantify seasonal changes in the maintenance energy requirements of Red Knots
(Calidris canutus islandica). This subspecies breeds on the tundra of northeast Canada and …
