Published: 1 April 2003
...Robert A. MacArthur; Gillian L. Weseen; Kevin L. Campbell SUMMARY We tested the hypothesis that the body oxygen stores, aerobic dive limit(ADL) and dive performance of muskrats can be enhanced by dive-conditioning in a laboratory setting. We compared several key variables in 12 muskrats trained...

...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...

...Daniel R. Streeby; Thomas A. McKean ABSTRACT Muskrats ( Ondontra zibethicus ) are common freshwater diving mammals exhibiting a bradycardia with both forced and voluntary diving. This bradycardia is mediated by vagal innervation; however, if hypoxia is present there may be local factors that also...

... 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...

...F. E. Fish ABSTRACT The surface swimming of muskrats ( Ondatra zibethicus Linnaeus) was studied by forcing individual animals to swim against a constant water current, of velocity ranging from 0·2 to 0·75 ms −1 , in a recirculating water channel. Lateral and ventral views of the swimming muskrats...
