Physiological features of embryonic development in terrestrially-breeding plethodontid salamanders,ze, rather than the need for energy during the protracted development. Large ovum size is associated with a slow rate of embryonic development which, together with the long RIT, accounts for the long incubation time..Rate of development increases with temperature within the temperature tolerance ran

Coupling of physiology of embryonic turtles to the hydric environment,ing animals, by affecting concentrations of urea in body fluids of embryos, by influencing growth of the allantois, and, indirectly, by affecting incubation temperature; water fluxes may influence duration of incubation via effects on water potential in compartments such as the yolk. However, the ev

Comparative aspects of calcium metabolism in embryonic reptiles and birds,d reptilian embryos, and studies of embryos of domestic fowl may not provide a broadly-based model with which to characterize calcium metabolism in embryos of other species. Control of calcium transport across the cellular epithelia (the yolk sac and chorioallantois) that separate embryos from their

Visual-Acuity

Respiratory gas transport system: similarities between avian embryos and lungless salamanders,and the body tissues are arranged essentially in parallel (not in series as in adult mammals and birds). The ‘cardiac output’, which essentially is equal to the sum of total systemic and gas exchange organ flows, is functionally comparable to double the ‘cardiac output’ in the sense used in mammalia

Blood oxygen affinity in relation to yolk-sac and chorioallantoic gas exchange in the developing chinity, due to progressive decrease in red cell [ATP], is adaptive in ensuring adequate O. saturation of arterialized blood. In Phase III, the transition to convective air-breathing and removal of the . , restriction on loading, the increase in P. is an advantage for O. delivery to tissues. This incr

Eggshell conductances of avian eggs at different altitudes, or fluctuated in a manner that was not correlated with the direction of change of P.. Average egg mass of one finch and several quail increased significantly following transport, but since this effect was also noted in control quail remaining at sea level for the entire period, the change is probab
