Mass stranding events (MSEs) of beaked whales (BWs) were extremely rare prior to the
1960s but increased markedly after the development of naval mid-frequency active sonar …

Large epipelagic fishes (> 30 kg maximum size) are known to display a variety of patterns of
vertical movement. Although advances in the affordability and sophistication of electronic …

Limited polar geographical range, narrowly defined migratory routes, and deep‐diving
behaviours make narwhals exceptionally vulnerable to anthropogenic disturbances …

Native cattle breeds represent an important cultural heritage. They are a reservoir of genetic
variation useful for properly responding to agriculture needs in the light of ongoing climate …

Several hormones are potential indicators of stress in free-ranging animals and provide
information on animal health in managed-care settings. In response to stress …

The mammalian diving response (DR) is a remarkable behavior that was first formally
studied by Laurence Irving and Per Scholander in the late 1930s. The DR is called such …

Until recent declines in Arctic sea ice levels, narwhals (Monodon monoceros) have lived in
relative isolation from human perturbation and sustained predation pressures. The resulting …

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 biology of the blue whale has long fascinated physiologists because of the animal's
extreme size. Despite high energetic demands from a large body, low mass-specific …

Reperfusion injury follows ischemia/reperfusion events occurring during myocardial
infarction, stroke, embolism, and other peripheral vascular diseases. Decreased blood flow …
