[Dynamics of body mass and oxygen consumption in the Iberian ribbed newt Pleurodeles waltl ontogenesis: 1. Endotrophic development].
The correlation between parameters of growth and energy metabolism in the example of embryonic and larval development of the Iberian ribbed newt Pleurodeles waltl has been studied. The wet body mass increases five times during this period due to water absorption by developing tissues and the yolk, and the dry mass decreases 1.18 times. The highest specific growth rate of developing tissues was noticed at the 33rd stage of embryogenesis (13th-14th day of development). These indexes decreased after the hatching, but increased after larvae switched to external nutrition. Comparison of the studied parameters has identified a similar features in alteration of the specific growth rate, intensity of oxygen consumption, and watering of developing tissues in early development of the Iberian ribbed newt.
