The aquatic habitat of marine “air-breathing” vertebrates provides a significant
thermoregulatory challenge due to the high thermal conductivity of water. In addition to …

The ability to maintain a high core body temperature is a defining characteristic of all
mammals, yet their diverse habitats present disparate thermal challenges that have led to …

A generalized bioenergetic model was used to estimate the food requirements of Steller sea
lions Eumetopias jubatus in Alaska, USA. Inputs included age-and sex-specific energy …

SUMMARY In Atlantic bottlenose dolphins Tursiops truncatus, both the thickness and lipid
content of blubber vary across ontogeny and across individuals of differing reproductive and …

Pinnipeds rely primarily on oxygen stores in blood and muscles to support aerobic diving;
therefore rapid development of body oxygen stores (TBO 2) is crucial for pups to transition …

Summary 1 Winter survival rate in Harbour Seal pups is significantly correlated with the
autumn body mass of pups. Multi‐type mark–recapture statistics were applied to individual …

Two key factors influence the diving and hence foraging ability of marine mammals:
increased oxygen stores prolong aerobic metabolism and decreased metabolism slows rate …

While foraging models of terrestrial mammals are concerned primarily with optimizing
time/energy budgets, models of foraging behaviour in marine mammals have been primarily …

Seals have adapted to the high heat transfer coefficient in the aquatic environment by
effective thermal insulation of the body core. While swimming and diving, excess metabolic …

Size-and age-specific physiological constraints coupled with inexperience make the
transition to independent foraging in juvenile divers a crucial period with important …
