It occupies the costomediastinic sinus and presents the cardiac notch. The ventral border of the left lung is slightly greater than the one of the right lung (Table 3). (B) Basal border: The basal border separates the base (or diaphragmatic surface) from the costal and medial surfaces.

Marine mammals are divided into three groups, with similar adaptations resulting from their aquatic lifestyle: sirenians, pinnipeds, and cetaceans. The present work focused on the South American fur seal, or Arctocephalus australis, a carnivore included in the pinnipeds group. We assessed whether the anatomical features of the Arctocephalus austral...

Over the past several decades, scientists have constructed bioenergetic models for marine mammals to assess potential population-level consequences following exposure to a disturbance, stressor, or environmental change, such as under the Population Consequences of Disturbance (pCOD) framework. The animal's metabolic rate (rate of energy expenditure...
