生理可塑性允许动物调整其生理功能以适应非生物和生物的变化。它主要是在对外部因素的反应的背景下进行研究，而对于动物如何调整其生理以科普内部条件的变化知之甚少。生殖过程意味着性腺成熟和其他内部变化，给动物带来各种挑战，例如对能量和氧气的需求增加。本研究采用延时摄影和代谢组学方法，对仿刺参（Apostichopus sp.）在繁殖过程中呼吸功能的调节能力及其生理机制进行了研究。结果表明，繁殖引起了中华绒螯蟹耗氧量的显著增加。- 是的有趣的是，养殖海参可以通过加快呼吸速率来适应高氧气需求。然而，为了在繁殖过程中保持必要的高水平呼吸活动，海参需要消耗大量的三磷酸腺苷（ATP）。此外，代谢组学数据表明，氧化应激和激素调节是连接生殖和呼吸功能的生理机制。总之，这些研究结果表明，呼吸功能的可塑性是一种有效的策略，以科普高氧气需求在生殖过程中。
Physiological plasticity allows animals to adjust their physiological function to abiotic and biotic variations. It has been mostly studied in the context of response to external factors and not much is known on how animals adjust their physiology to cope with variations in internal conditions. The process of reproduction implies gonadal maturation and other internal changes, bringing various challenges to the animal such as an increased demand for energy and oxygen. Here, the capacity of the sea cucumber, Apostichopus japonicus to adjust its respiratory function and physiological mechanisms during reproduction was studied using a time-lapse videography and metabolomics approach. The results showed that reproduction caused a significant increase in oxygen consumption in A. japonicus. Interestingly, breeding sea cucumbers can accommodate the high oxygen demand by accelerating respiratory rate. However, to maintain a necessary high level of respiratory activity during reproduction, sea cucumbers need consume large amounts of adenosine triphosphate (ATP). In addition, the metabolomic data suggests that oxidative stress and hormone regulation are the physiological mechanisms linking reproduction and respiratory function. Altogether, these findings suggest that plasticity of respiratory function is an effective tactic to cope with high oxygen demand during reproduction.
