Repeatability of basal metabolism in breeding female kittiwakes Rissa tridactyla
We studied kittiwakes (Rissa tridactyla) breeding near Ny–Ålesund (79° N, 12° E) on Svalbard. In 1997, the basal metabolic rates (BMRs) of 17 breeding females were measured during the incubation andExpand

Basal metabolic rate: heritability and genetic correlations with morphological traits in the zebra finch
Studies of genetic variation in metabolic traits have so far not focused on birds. In our study population of captive zebra finches we found evidence for a significant heritable genetic component inExpand

Long-term repeatability makes basal metabolic rate a likely heritable trait in the zebra finch Taeniopygia guttata
SUMMARY Basal metabolic rate (BMR) is a physiological trait believed to show adaptational changes. Few studies have tested whether BMR shows stable between-individual variations. RepeatabilityExpand

Thermoregulation in winter-acclimatized common eiders (Somateria mollissima) in air and water
Metabolic heat production, body temperature, and skin temperatures of the back and breast were measured and the thermal conductance, and thus insulation, estimated in winter-acclimatized commonExpand

The relationship between social status and resting metabolic rate in great tits (Parus major) and pied flycatchers (Ficedula hypoleuca)
The oxygen consumption of great tits (Parus major) in winter flocks and of male pied flycatchers (Ficedula hypoleuca) in breeding condition, was measured. Resting metabolic rate was significantlyExpand

Individual Variation in Field Metabolic Rate of Kittiwakes (Rissa tridactyla) during the Chick‐Rearing Period
Field metabolic rate (FMR), using the doubly labelled water (DLW) method, was measured in free‐ranging adult kittiwakes (Rissa tridactyla) early and late in the chick‐rearing period at Svalbard,Expand

To breed or not to breed: endocrine response to mercury contamination by an Arctic seabird
Mercury, a ubiquitous toxic element, is known to alter expression of sex steroids and to impair reproduction across vertebrates but the mechanisms underlying these effects are not clearly identified.Expand

Organohalogen contamination in breeding glaucous gulls from the Norwegian Arctic: associations with basal metabolism and circulating thyroid hormones.
Exposure to organohalogens in endotherms has been suggested to impose chemically induced stress by affecting functions related to maintenance energy requirements. Effects on basal metabolic rateExpand

Census of breeding Antarctic petrels Thalassoica antarctica and physical features of the breeding colony at Svarthamaren, Dronning Maud Land, with notes on breeding snow petrels Pagodroma nivea and
Only about a dozen breeding colonies of the Antarctic Petrel Thalassoica antarctica are known, all confined to the Antarctic continent. In 1985 one of the largest colonies, situated inExpand

Metabolic ageing in individual zebra finches
Oxidative stress is suggested as a contributor to the ageing process. Knowledge of the relationship between age and energy expenditure may contribute to our understanding of ageing patterns, due toExpand
