... of environmental interactions, behavioral flexibility and morphological constraints on energy balance, we used doubly labeled water to measure the at-sea daily energy expenditure (DEE) of two sympatrically breeding seabirds, Campbell ( Thalassarche impavida ) and grey-headed ( Thalassarche chrysostoma...

...T. Todd Jones; Mervin D. Hastings; Brian L. Bostrom; Russel D. Andrews; David R. Jones SUMMARY Marine turtles often have extremely high water turnover accompanied by a low field metabolic rate (FMR), a combination that can contraindicate the use of doubly labelled water (DLW). Therefore, we...

...Kenneth A. Nagy SUMMARY The field metabolic rates (FMRs) of 229 species of terrestrial vertebrates,all measured using the doubly labeled water method in free-living individuals,were evaluated. Daily rates of energy expenditure were as low as 0.23 kJ per day in a small reptile (gecko), to as high...

...-living individuals have been made using doubly labeled water. Prior to extirpation of this species in the wild in 1972, conservationists sequestered a number of individuals for captive breeding; in 1989, oryx were reintroduced in Saudi Arabia into Mahazat as-Sayd (2244km 2 ). Apart from small pools...

...Marcus D. Webster; Wesley W. Weathers ABSTRACT We used the doubly labeled water ( DLW ) method to measure field metabolic rate ( FMR ) and water turnover during winter and summer in a very small (6.5 g) insectivorous desert passerine bird, the verdin ( Auriparus flaviceps ). Concurrently, we...
