由于气候变化和其他人为压力因素，全球水生系统中的氧气生物利用度正在下降。对水生生物而言，其后果尚不清楚，但很可能反映了氧气生物利用度下降的直接影响，以及氧气与其他压力源（包括二次变暖和酸化）之间的相互作用——近几十年来受到了大量关注，通常伴随着氧气的变化。根据本次研讨会文集（“气候变化中的氧气视角”）中收集的论文，我们概述了氧气生物利用度下降的原因和后果。首先，我们讨论了水生氧气水平的自然和预测的人为变化的范围。尽管现代生物是长期暴露于自然氧气环境下的进化历史的结果，但人为变化现在使它们暴露于更极端的条件和低氧与其他压力源的新组合。其次，我们确定了氧气与其他应激源相互作用的行为和生理机制，并评估了生物组织在多个时间尺度上对氧气限制的潜在有机体反应范围。我们认为，代谢和能量学为理解生物体与氧气的相互作用提供了一个强大而统一的框架。最后，我们概述了一套最大化未来工作效率的方法，包括关注使用实验因素的生物学现实变化的长期实验，并采取真正的跨学科和综合方法来理解和预测未来的影响。

Oxygen bioavailability is declining in aquatic systems worldwide as a result of climate change and other anthropogenic stressors. For aquatic organisms, the consequences are poorly known but are likely to reflect both direct effects of declining oxygen bioavailability and interactions between oxygen and other stressors, including two—warming and acidification—that have received substantial attention in recent decades and that typically accompany oxygen changes. Drawing on the collected papers in this symposium volume (“An Oxygen Perspective on Climate Change”), we outline the causes and consequences of declining oxygen bioavailability. First, we discuss the scope of natural and predicted anthropogenic changes in aquatic oxygen levels. Although modern organisms are the result of long evolutionary histories during which they were exposed to natural oxygen regimes, anthropogenic change is now exposing them to more extreme conditions and novel combinations of low oxygen with other stressors. Second, we identify behavioral and physiological mechanisms that underlie the interactive effects of oxygen with other stressors, and we assess the range of potential organismal responses to oxygen limitation that occur across levels of biological organization and over multiple timescales. We argue that metabolism and energetics provide a powerful and unifying framework for understanding organism-oxygen interactions. Third, we conclude by outlining a set of approaches for maximizing the effectiveness of future work, including focusing on long-term experiments using biologically realistic variation in experimental factors and taking truly cross-disciplinary and integrative approaches to understanding and predicting future effects.
