BASAL METABOLIC RATE AND THERMAL CONDUCTANCE IN ARCTIC TERN CHICKS AND THE EFFECT OF HEAT INCREMENT OF FEEDING ON THERMOREGULATORY EXPENSES

ABSTRACT Chick basal metabolic rate (BMR c ) as oxygen consumption (V0 2 in ml O 2 g-l h-l ) ofunfed individuals ofArctic Terns Sterna paradisaea during development (12 -109 g) was best described by the parabolic equation V0 2 = 1.25 + 0.061m -0.00047m 2 , where m is body mass in g. Interspecific co...

Description
Summary:ABSTRACT Chick basal metabolic rate (BMR c ) as oxygen consumption (V0 2 in ml O 2 g-l h-l ) ofunfed individuals ofArctic Terns Sterna paradisaea during development (12 -109 g) was best described by the parabolic equation V0 2 = 1.25 + 0.061m -0.00047m 2 , where m is body mass in g. Interspecific comparison of hatchling BMR c revealed a relatively high BMR c in Arctic Tern hatchlings, in accordance with an increase in BMR c with latitude for hatchling terns 'Zoological Laboratory RUG.2Department of Zoology, University of Trondheim, N-7055 Dragvoll, Norway.3Research Institute for Nature Management
