Ontogeny Influences the Capacity for Bradycardia in Dolphins
Meeting Abstract 61.8 Friday, Jan. 6 Ontogeny Influences the Capacity for Bradycardia in Dolphins NOREN, S.R.*; WILLIAMS, T.M.; UC Santa Cruz; UC Santa Cruz norenkramer@yahoo.com Bradycardia is a key component of the dive response that facilitates prolonged breath-holds of marine mammals. Previous research demonstrated that mean steady-state heart rate (HR) during 2-3 min dives was greater for […]
