Abstract

Fuel economy matters to both animals and machines, as the cost of transport can determine where, when, and how far locomotion is possible. However, established estimates of these values for animal flight come from laboratories and treat the atmosphere as constant, even though free-flying animals routinely extract energy from atmospheric flows. Using high-resolution movement data, we estimate the cost of transport for 50 bird and bat species flying in the wild. Our results revise the classic ranking of locomotion costs, suggesting that flying can be cheaper than swimming though almost as costly as running, depending on interactions between physical environment, morphology, and behavior. Linking transport costs to atmospheric conditions provides a mechanistic basis for predicting how changing windscapes will reshape the energetics, movements, and distributions of flying animals.

气流重新定义了野外空中运输的成本

燃料经济性对动物和机器都很重要，因为运输成本可以决定运动的地点、时间和距离。然而，对动物飞行的这些值的既定估计来自实验室，并将大气视为常数，即使自由飞行的动物通常从大气流动中获取能量。利用高分辨率的运动数据，我们估计了50种鸟类和蝙蝠在野外飞行的运输成本。我们的研究结果修正了经典的运动成本排名，表明飞行可以比游泳更便宜，尽管几乎和跑步一样昂贵，这取决于物理环境、形态和行为之间的相互作用。将运输成本与大气条件联系起来，为预测变化的景观如何重塑飞行动物的能量学、运动和分布提供了机制基础。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
