Time domains of the hypoxic cardio-respiratory response in bowfin (Amia calva).

Highlights: [•] The hypoxic ventilatory response (HVR) of bowfin to hypoxia was measured. [•] The HVR of bowfin without access to air exhibited time domains similar to those of mammals. [•] The HVR of bowfin with access to air did not exhibit time domains. [•] Bowfin without access to air exhibited a tachycardia during recovery from hypoxia. [Copyright &y& Elsevier]
