A predictable late embryonic bradycardia (relative to normal White Leghorn chickens) has been documented in chicken strains with C locus mutations. The basis of the bradycardia remains unknown but clearly is related to a mutation at the C locus, whic

Ballistocardiography or impedance cardiography was used to measure on a daily basis the heart rate ($f_{H}$) of embryos of altricial pigeons (Columba domestica) and bank swallows (Riparia riparia). The patterns of $f_{H}$ changes during development w

The central cardiovascular function of amphibians has been studied in detail for many decades. Some investigators have been motivated primarily by the search for supposedly simple models which may provide a greater understanding of the circulations o

Although most research on developmental cardiovascular physiology has focused on the bird embryo as a model for emulating developmental processes in mammals, there are increasingly compelling reasons to expand research to a variety of lower vertebrat

Systemic arterial blood pressure and heart rate (fH) were measured in unanesthetized, unrestrained larvae and adults of the paradoxical frog, Pseudis paradoxus from Sao Paulo State in Brazil. Four developmental groups were used, representing the comp

In the conscious, undisturbed toad, Bufo marinus, pulmonary arterial blood flow increased during periods of lung ventilation and decreased in intervening periods of pulmonary apnea. In unidirectionally ventilated, anesthetized toads, lung inflation p

The significance of skin ventilation to cutaneous gas exchange in vertebrates has seldom been recognized. Unlike the lungs and gills, the skin lacks a dedicated ventilatory pump, and most analyses have implicitly or explicitly ignored skin ventilatio

The interaction between lung and gill ventilation was investigated in unanesthetized Rana catesbeiana larvae (stage XVII-XIX) in hypoxic (PO2 = 80 +/- 1 Torr), normoxic (PO2 = 142 +/- 1 Torr), and hyperoxic (PO2 = 580 +/- 23 Torr) water. Lung inflati

Water flow within the branchial chamber, blood flow within the gill filaments, and the fine structure of the gill epithelium have been determined in the crayfish Procambarus clarkii. The epithelium of the podobranch filaments, which is 3.15–8.70 μ
