Decompression theory has been mainly based on studies on terrestrial mammals, and may
not translate well to marine mammals. However, evidence that marine mammals experience …

The giant rorqual whales are believed to have a massive food turnover driven by a high-
intake lunge feeding style aptly described as the world's largest biomechanical action. This …

The air volume in the respiratory system of marine tetrapods provides a store of O2 to fuel
aerobic metabolism during dives; however, it can also be a liability, as the associated N2 …

Arctic marine mammals live in a rapidly changing environment due to the amplified effects of
global warming. Pacific walruses (Odobenus rosmarus divergens) have responded to …

Walruses rely on sea-ice to efficiently forage and rest between diving bouts while
maintaining proximity to prime foraging habitat. Recent declines in summer sea ice have …

In the current study, we used breath-by-breath respirometry to evaluate respiratory
physiology under voluntary control in a male beluga calf [Delphinapterus leucas, body mass …

Many animal species do not breathe in a continuous, rhythmic fashion, but rather display a
variety of breathing patterns characterized by prolonged periods between breaths (inter …

Echocardiography is commonly used in veterinary clinical practice for many species but is
not as easily applied in non-sedated marine mammals. Additionally, Doppler …

Pulmonary function testing was performed in 3 bottlenose dolphins Tursiops truncatus (1
female and 2 males) under managed care during a 2 yr period to assess whether these data …

In the present study, we examined lung function in healthy resting adult (born in 2003)
Pacific walruses (Odobenus rosmarus divergens) by measuring respiratory flow () using a …
