TLDR
Rates of CO2 production in free-living and captive howler monkeys were mea'sured using doubly labeled water, and assimilation of energy from natural foods was determined, permitting construction of a field energy budget, and estimation of the feeding rate of these arboreal, plant-eating primates.Abstract:
Rates of CO2 production in free-living and captive howler monkeys were mea'sured using doubly labeled water, and assimilation of energy from natural foods was determined. Results permit construction of a field energy budget, and estimation of the feeding rate of these arboreal, plant-eating primates. Field metabolic rates averaged 355 kJ kg-1 day-1 (=2x basal metabolic rate). Assimilation of the energy in a fruit and leaf diet was =400o. Feeding rate in the field is estimated to be =54 g dry matter kg-1 day-1, or =90 kg dry matter ha-1 yr-1.read more

Population density and body size in mammals
TL;DR: Density is related approximately reciprocally to individual metabolic requirements, indicating that the energy used by the local population of a species in the community is independent of its body size.

Field metabolic rate and food requirement scaling in mammals and birds
TL;DR: Field metabolic rates (FMRs or HF), all measured using doubly labeled water, of 23 species of eutherian mammals, 13 species of marsupial mammals, and 25 species of birds were summarized and analyzed allometrically (log10-1og10 regressions).

Energetics of free-ranging mammals, reptiles, and birds.
TL;DR: The difference between allometric slopes for marsupials and eutherians is no longer significant and the slope difference between Scleroglossan and Iguanian lizards disappears as well, but other taxonomic differences remain significant.

Interspecific allometry of population density in mammals and other animals: the independence of body mass and population energy‐use
TL;DR: It is suggested that rough independence of body mass and the energy-use of local populations is a widespread rule of animal ecology and community structure.

Comparative primate energetics and hominid evolution
TL;DR: The ecological correlates of variation in metabolic requirements among extant primate species is examined, and inferences about the changes in energy demands over the course of human evolution are drawn.

Theory of use of the turnover rates of body water for measuring energy and material balance
TL;DR: A summary is given of tests of the extent to which theoretical expectations are realized on the use of isotopically determined turnover rates of the hydrogen and oxygen of body water for measurement of total energy and material balance of an animal.
