Abstract We describe a dynamic energy budget (DEB) model for tadpoles over the course of metamorphosis. The model accounts for details in the tadpoles feeding behavior, as feeding and indirectly respiration are reduced in the late developmental stages preceding metamorphosis to an immature froglet. We propose two versions of our DEB model, one where the energy reserves of the organism are accounted for explicitly (a variant on Kooijman’s ”standard” DEB model), and one where reserves and structural biomass are lumped together so that only the size of the organism is tracked (a variant on DEBkiss). Both models are parameterized using a time series of measurements on a cohort of tadpoles of the Pacific tree frog, Pseudacris regilla. The models describe tadpoles from the middle of their development as tadpoles until they emerge as froglets. Visually, both models fit the growth and respiration empirical data reasonably well; statistically the fit to the full DEB model is slightly better. The models highlight the metabolic changes during the life of a tadpole and demonstrate how morphological changes in developing organisms can be accomodated in the DEB framework.

接近变态的蝌蚪的能量收支

摘要 我们描述了蝌蚪在变态过程中的动态能量收支（DEB）模型。该模型解释了蝌蚪摄食行为的细节，因为在变态为未成熟的青蛙之前的发育晚期阶段，摄食和间接呼吸减少。我们提出了两个版本的 DEB 模型，一个版本明确考虑了生物体的能量储备（Kooijman 的“标准”DEB 模型的一个变体），另一个版本将储备和结构生物量集中在一起，以便只有生物体被跟踪（DEBkiss 的一个变体）。两个模型都使用对太平洋树蛙 Pseudacris regilla 蝌蚪群的时间序列测量进行参数化。这些模型将蝌蚪从发育中期描述为蝌蚪，直到它们出现为青蛙。视觉上，两个模型都很好地拟合了生长和呼吸的经验数据；从统计上看，对完整 DEB 模型的拟合稍好一些。这些模型突出了蝌蚪生命期间的代谢变化，并展示了如何在 DEB 框架中适应发育中生物体的形态变化。
