Thermoregulatory variables were measured in captive beluga and killer whales to confirm earlier work on smaller cetaceans. Whales had body temperatures within mammalian range and maintained a skin-water temperature difference of about 2° C. Heat-loss coefficients were less than that reported for humans. Thermal conductance may be greater than or equal to small cetaceans and humans. The larger killer whales had smaller surface-area-to-volume ratios than the belugas, as expected. However, the… Expand
The diving physiology of bottlenose dolphins (Tursiops truncatus). III. Thermoregulation at depth.
TLDR
It is indicated that heat dissipation by dolphins is attenuated during diving, rather than challenge the diving response, heat transfer is delayed until post-dive periods when the need for oxygen conservation is reduced. Expand
Metabolic rates of minke whales (Balaenoptera acutorostrata) in cold water.
TLDR
Estimates of oxygen consumption based on records of f and Ve, and data on oxygen extraction from other cetaceans, yielded a range of metabolic rates which compared nicely with the calculated HL values. Expand
Field energetics and lung function in wild bottlenose dolphins, Tursiops truncatus, in Sarasota Bay Florida
TLDR
These measurements provide novel data for resting energy use and respiratory physiology in wild cetaceans, which may have significant value for conservation efforts and for understanding the bioenergetic requirements of this species. Expand
Seasonal Resting Metabolic Rate and Food Intake of Captive Pacific White-Sided Dolphins (Lagenorhynchus obliquidens)
TLDR
Estimates of resting metabolic rates and relative changes in total energy intake can be used to parameterize bioenergetic models needed to estimate the ecological impacts and energetic requirements of Pacific white-sided dolphins in the wild, which will have conservation implications. Expand
Energy requirements of Pacific white-sided dolphins (Lagenorhynchus obliquidens) as predicted by a bioenergetic model
TLDR
These high energetic requirements of Pacific white-sided dolphins may indicate a reliance of dolphins on energy-rich prey, which has implications for fisheries management and conservation of marine mammals. Expand
Thermoregulation in feeding baleen whales: Morphological and physiological evidence
TLDR
Morphological structures for heat conservation in the tongues of gray whales are described here in detail, finding that these heat exchangers substantially reduce heat loss when these whales feed in cold waters. Expand
Broad thermal capacity facilitates the primarily pelagic existence of northern fur seals (Callorhinus ursinus)
TLDR
Comparing this broad thermal neutral zone to the average sea surface temperatures potentially encountered during annual migrations indicates wild fur seals can likely exploit a large geographic area without added thermal metabolic costs. Expand
Do Cetaceans Really Have Elevated Metabolic Rates?
TLDR
When comparing their data from whales with basal metabolic rates of other homeotherms, Kasting et al. (1989) use animals that do not satisfy Kleiber's (1975) criteria because their method for estimating metabolic rates is flawed. Expand
Blubber Deposition During Ontogeny in Free-Ranging Bottlenose Dolphins: Balancing Disparate Roles of Insulation and Locomotion
TLDR
Balancing energetic demands of thermoregulation and locomotion may limit the flexibility of yearlings to adjust blubber deposition in response to fluctuating water temperatures. Expand
Comparative Respiratory Physiology in Cetaceans
TLDR
Breath-by-breath respirometry data provide enhanced understanding of the respiratory physiology of cetaceans and are useful to provide proxies of lung function to better understand lung health or physiological limitations. Expand

Body temperature and heat exchange in the Hawaiian spinner dolphin, Stenella longirostris.
TLDR
It is concluded that these small tropical cetaceans live close to their lower critical temperatures, and depend upon the energy produced by activity, from solar radiation, and marked control over the peripheral insulation to maintain thermal balance. Expand
Metabolic rates of seals and whales
TLDR
A critical review of metabolic rate determinations for pinnipeds and cetaceans does not support the widely accepted generalization that they have higher metabolic rates than terrestrial mammals of similar size, forcing a rethinking of the thermoregulatory adaptations of these marine mammals for an aquatic existence.

TLDR
For the whales, blood circulation to the dermal layer below appendage and body skin surfaces proved to be essential for sufficient heat dissipation, and blubber thickness was found to be of minor importance in whale thermoregulation. Expand
THERMOREGULATORY ADAPTATIONS IN MARINE MAMMALS: INTERACTING EFFECTS OF EXERCISE AND BODY MASS. A REVIEW1
TLDR
There is evidence for a powerful control of thermoregulatory mechanisms by the anterior hypothalamic/preoptic region of the brain in two species and Thermoregulation in marine mammals during exercise remains paradoxical. Expand

TLDR
The body wall serves as a flexible insulator while the dorsal fin is a major site of heat dissipation in Hawaiian spinner and Pacific bottlenose dolphin. Expand

Between limits of 100-250% of resting heat loss the following relationships between MSF and equivalent water-air temperatures were found (see article). Expand
Energy exchanges of swimming man.

Three male swimmers underwent 10-min resting and 20-min swimming (breaststroke) exposures in a swimming flume and internal body temperature changes after 20 min of swimming were related to water temperature, swimming intensity, and body composition. Expand

This book is a magnificent synthesis of scientific information on the basis of Lavoisier's important dictum that respiration is a kind of combustion and the repeated mention of Malthus and "writers with a hate complex". Expand
