Comp Biochem Physiol A Mol Integr Physiol 126:143-51. 2000..Current physiological research is focused on factors, such as heart rate and temperature, which potentially affect the diving metabolic rate and duration of aerobic diving... - Myoglobin in pelagic small cetaceansM L Dolar
Scripps Institution of Oceanography, La Jolla, CA 92093 0204, USA
J Exp Biol 202:227-36. 1999..As in other species, the increase in [Mb] during development probably parallels the development of diving capacity... - Post-dive blood lactate concentrations in emperor penguins, Aptenodytes forsteriP J Ponganis
Scripps Institution of Oceanography, University of California, San Diego, La Jolla 92093 0204, USA
J Exp Biol 200:1623-6. 1997..These are the first determinations of post-dive lactate concentrations in any free-diving bird and are currently the only physiological assessment of an ADL in an avian species... - Heart rate and plasma lactate responses during submerged swimming and trained diving in California sea lions, Zalophus californianusP J Ponganis
Center for Marine Biotechnology and Biomedicine, Scripps Institution of Oceanography, University of California, San Diego, La Jolla 92093 0204, USA
J Comp Physiol B 167:9-16. 1997..The aerobic dive limit, calculated with these O2 stores and prior measurements of at-sea metabolic rates of sea lions, is 1.8-2 min, similar to that measured by the change in post-submersion lactate concentration... - Energetic cost of foraging in free-diving emperor penguinsK A Nagy

Physiological Research Laboratory, Scripps Institution of Oceanography, University of California, San Diego
J Comp Physiol B 160:473-82. 1990..The cardiovascular performance of seals at the maximum MO2 we could induce from them is equivalent to that of the domestic goat...
