School of Biological Sciences, University of Queensland, St Lucia, Queensland 4072, Australia
Proc Biol Sci 277:3837-44. 2010
..If the study findings are common among air-breathing diving ectotherms, then long-term warming of the aquatic environment may be detrimental to behavioural function and survivorship...
- Does respiratory sinus arrhythmia occur in fishes?

Biol Lett 1:484-7. 2005
..This evidence that vagally mediated control of fH operates around the ventilatory cycle in fish demonstrates that influences similar to those controlling RSA in mammals operate in non-mammalian vertebrates...
The vagus nerve mediates cardio-respiratory coupling that changes with metabolic demand in a temperate nototheniod fishHamish A Campbell

J Exp Biol 210:2472-80. 2007
..Thus, P. angustata exhibits vagally mediated CRC, and the association between fH and fV varies according to oxygen demand...

J Exp Biol 214:2883-95. 2011
..These data suggest that NHE3 and NKA together may be important in mediating branchial Na(+) uptake in freshwater environments, whereas PDN and VHA might contribute to Cl(-)/HCO(3)(-) transport in marine and freshwater bull shark gills...
- Evidence for a respiratory component, similar to mammalian respiratory sinus arrhythmia, in the heart rate variability signal from the rattlesnake, Crotalus durissus terrificus

J Exp Biol 209:2628-36. 2006
..Therefore, this study has demonstrated the presence of RSA in the HRV signal and a dual location for VPN in the rattlesnake. We suggest there to be a causal relationship between these two observations...
