The Characterisation of Underwater Noise at Facilities Holding Marine Mammals

A collaborative effort was undertaken to delineate underwater noise levels within holding enclosures at marine mammal facilities. Ambient noise levels were measured under normal operating conditions in the enclosures of 14 participating facilities. Facility habitats varied from ocean environments to fully enclosed pools. The means and standard errors of the noise pressure spectral densities measured […]

Vitamin D content in Alaskan Arctic zooplankton, fishes, and marine mammals

Abstract 10.1002/zoo.10104.abs We postulated that dietary ingestion of vitamin D may be used by some Alaskan Arctic marine mammal species in addition to, or instead of, cutaneous production to meet nutritional requirements. Zooplankton (n=5) sampled near Kaktovik, Alaska, contained no measurable vitamin D2 or D3, but did contain provitamin D (7-dehydrocholesterol), the cutaneous precursor for […]

Body mass and food intake in captive, breeding bottlenose dolphins, Tursiops truncatus

Abstract 10.1002/zoo.1430100603.abs Body mass (BM) was recorded regularly during pregnancy in four female Indian Ocean bottlenose dolphins (Tursiops truncatus). Daily food intakes were recorded for each animal before and after parturition. BM increase occurred variably between 2 and 5 months of gestation, and at parturition mass increases averaged 41.2% of initial prepregnancy mass. Changes in […]
