Influence of Hypoxia and Adrenaline Administration on Coronary Blood-Flow and Cardiac-Performance in Seawater Rainbow-Trout (Oncorhynchus-Mykiss)
To investigate the relationship between cardiac performance and coronary perfusion, cardiovascular variables (Q, Vs, fH, PDA) and coronary blood flow (q(cor)) were measured in rainbow trout (Oncorhynchus mykiss) (1.2-1.6 ... -
Larval cardiorespiratory ontogeny and allometry in Xenopus laevis
Very little is known about the early development of cardiorespiratory regulatory mechanisms in newly hatched amphibian larvae. We tested whether early cardiovascular responses to hypoxia reflect local flow regulation in ... -
Oxygen transport in egg masses of the amphibians Rana sylvatica and Ambystoma maculatum: Convection, diffusion and oxygen production by algae
Many amphibians lay their eggs in gelatinous masses up to 10-20 cm in diameter, posing problems for diffusive oxygen delivery. Oxygen may also be provided by water convection between eggs or by oxygen production by endogenous ... -
The respiratory development of Atlantic salmon .1. Morphometry of gills, yolk sac and body surface
During development from larva to juvenile in Atlantic salmon, Salmo salar, there is a change in the anatomical potential for gas exchange among gills, body skin and yolk sac as the larvae resorb yolk, grow and develop ... -
The respiratory development of Atlantic salmon: II. Partitioning of oxygen uptake among gills, yolk sac and body surfaces
During post-hatch development of Atlantic salmon (Salmo salar L.), O-2 uptake partitioning changes from primarily cutaneous to primarily branchial. Over 80% of post-hatch O-2 uptake was cutaneous, with the yolk sac responsible ...
