... Ondatra zibethicus A recent trend in vertebrate diving research has been the growing emphasis on studies directed at intraspecific variability in dive performance (see Burns and Castellini, 1996 ; Burns et al., 1997 ; MacArthur et al., 2001 ). To date, most of this research has focused...

...Pierre E. Signore; David R. Jones ABSTRACT Neural control of the cardiac responses to exercise in air (running) and under water (diving) was studied in the muskrat ( Ondatra zibethicus ) by means of acute pharmacological blockade with the muscarinic blocker atropine and the β-adrenergic blocker...

...Pierre E. Signore; David R. Jones ABSTRACT Neural control of free and forced diving bradycardia and peripheral resistance was studied in the muskrat ( Ondatra zibethicus ) by means of acute pharmacological blockade with the muscarinic blocker atropine, the α -adrenergic blocker phentolamine...

... of the semi-aquatic diving rodent, the muskrat ( Ondatra zibethicus ), is able to survive ischemia and hypoxia better than the heart of a similarly sized non-diving rodent, the guinea pig ( McKean and Landon, 1982 ; McKean, 1984 ). We hypothesized that the K ATP channel might be involved in the explanation...
