Effects Of Age, Mass, And Terrestrial Duration On Oxygen Store Development In Phocids And Otariids, Rachael M. Stevenson

HCNSO Student Capstones

Diving ontogeny among pinniped species was explored to determine how oxygen store development was affected by age, mass, and terrestrial duration between Phocidae and Otariidae. Distinct physiological and post-natal developmental differences exist between the two families which contribute to oxygen store and diving development. Blood oxygen data for six phocids and otariids and muscle oxygen data for two phocids and otariids were obtained. Body mass significantly (p
