We studied growth and respiration rate during early ontogenesis of the axolotl Ambystoma mexicanum, Bosca's newt Triturus waltlii, the green toad Bufo viridis, and the smooth clawed frog Xenopus laevis. The respiration rate in these amphibian species increases during embryonal and larval development, peaks after transition to active feeding, and decreases at later stages of ontogenesis. The patterns of dynamics of this energy metabolism index in tailed and tailless amphibians have some differences related to their specific development. The changes in respiration rate in the embryos and larvae are correlated with the concentrations of mitochondria.
我们研究了美西钝口螈、博氏螈、绿蟾蜍和非洲爪蟾在个体发育早期的生长和呼吸速率。这些两栖类物种的呼吸速率在胚胎期和幼体发育期间增加，在转变为主动摄食后达到峰值，并在个体发育后期下降。有尾和无尾两栖动物这种能量代谢指标的动态模式存在一些与其特定发育相关的差异。胚胎和幼体呼吸速率的变化与线粒体浓度相关。
