...José Guadalupe Soñanez-Organis; José Pablo Vázquez-Medina; Tania Zenteno-Savín; Andres Aguilar; Daniel E. Crocker; Rudy M. Ortiz SUMMARY Northern elephant seals are naturally adapted to prolonged periods (1–2 months) of absolute food and water deprivation (fasting). In terrestrial mammals, food...

... predators carrying large blubber reserves intended for thermoregulation in cold water and fuel provision during extended fasts. Thermographic images were used to measure changes in skin temperature ( T S ) in adult male northern elephant seals ( Mirounga angustirostris ) over the breeding season...

... the use of stomach temperature telemetry to identify and quantify prey consumed in both a phocid (northern elephant seal Mirounga angustirostris ) and an otariid (California sea lion Zalophus californianus ) species. In addition, we used opportunistic water consumption by northern elephant seals to test...

...Rudy M. Ortiz; Charles E. Wade; C. Leo Ortiz; Frank Talamantes SUMMARY The physiological actions of vasopressin (VP) in marine mammals are not well defined. To help elucidate its hormonal and renal effects in this group of mammals, northern elephant seal ( Mirounga angustirostris ) pups( N =7; 99±4...

... in buoyancy and diving behavior in northern elephant seals Mirounga angustirostris . This was achieved by modifying the buoyancy of 13 juvenile elephant seals translocated from Año Nuevo State Reserve, CA, USA, and released at various sites in Monterey Bay, CA, USA. The buoyancy of each seal was calculated...
