The metabolic cost of swimming and reproduction in harbor porpoises (Phocoena phocoena) as predicted by a bioenergetic model
While harbor porpoises currently enter San Francisco Bay year-round, evidence suggests a disappearance that spanned approximately 65 yr. The range of energetic costs of basal metabolism, locomotion, thermoregulation, and reproduction was estimated for porpoises, using a velocity-dependent bioenerget...
