This report examines the evidence for the presence of oxygen stores in the lungs, blood and
systemic musculature of diving mammals, the modifications in the respiratory functions of …

The average respiratory quotient of weasels was 0.73. There were significant differences in
average daily metabolic rate (ADMR) between the sexes and six experimental temperatures …

Marine mammals exhibit multi-level adaptations, from cellular biochemistry to behavior, that
maximize aerobic dive duration. A dive response during aerobic dives enables the efficient …

Rates of oxygen consumption and CO2 production were measured in Virginia opossums
(Didelphis virginiana) during fasting and prolonged exercise to quantify changes in total …

Controlled feeding experiments were undertaken with captive Steller sea lions (Eumetopias
jubatus) to assess seasonal (winter vs. summer) physiological responses of individual …

To be successful, marine predators must alter their foraging behavior in response to
changes in their environment. To understand the impact and severity of environmental …

During sustained bouts of diving, predators such as fur seals may adjust the time they spend
diving to maximize the time they can spend foraging and minimize the time spent at the …

The physiological and behavioural development of diving was examined in Australian fur
seal (Arctocephalus pusillus doriferus) pups to assess whether animals at weaning are …

Time and energy are the two most important currencies in animal bioenergetics. How much
time animals spend engaged in different activities with specific energetic costs ultimately …
