Elephant seals : population ecology, behavior, and physiology
TLDR
This study of the elephant seal brings together an international group of scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals.

Male-male Competition and Reproductive Success in Elephant Seals
Male-male competition and reproductive success of northern elephant seals, Mirounga augustirostris , was studied for six consecutive breeding seasons at Ano Nuevo Island, California. The conclusionsExpand
FORAGING ECOLOGY OF NORTHERN ELEPHANT SEALS
Sexual segregation in foraging is predicted from the great size disparity of male and female northern elephant seals, Mirounga angustirostris. Our aim was to test this prediction by measuring divingExpand
Water and Energy Flux in Elephant Seal Pups Fasting under Natural Conditions
TLDR
It is concluded that a combination of behavioral and physiological water conservation mechanisms permit these animals to fast on land for up to 3 mo, deriving necessary water and energy from the oxidation of fat stores. Expand
Drift diving in female northern elephant seals: implications for food processing
TLDR
Predictions from the hypothesis that northern elephant seals drift during the bottom segment of some dives (called C dives) using oxygen saved from reduced locomotion to process food are tested. Expand
Expanded niche for white sharks
TLDR
The tracking of movements of white sharks is reported by using pop-up satellite archival tags, which reveal that their migratory movements, depth and ambient thermal ranges are wider than was previously thought. Expand
Behavioral and physiological measurements of maternal investment in the Steller sea lion, Eumetopias jubatus
TLDR
It is suggested that female attendance patterns are shaped by the increasing nutritional demands of growing pups and their increasing efficiency at suckling and that heavier pups consumed more milk than lighter ones. Expand
Continuous, deep diving in female northern elephant seals, Mirounga angustirostris
The free-ranging dive pattern of seven adult female northern elephant seals (Mirounga angustirostris) was obtained with time–depth recorders during the first 14 – 27 days at sea following lactation.Expand
Female competition and reproductive success in northern elephant seals
The probability of weaning a healthy pup increases with age in female northern elephant seals, Mirounga angustirostris. On Ano Nuevo Island, California, weaning success among ‘prime’ females, those 6Expand
Autonomous Pinniped Environmental Samplers: Using Instrumented Animals as Oceanographic Data Collectors
Data-recording tags applied to marine animals store data for later retrieval and can return valuable information on animal behavior and ecology, including habitat preference, physiology, and movementExpand
