Abstract

Natural selection has repeatedly led to the evolution of two alternative antipredator color strategies—camouflage to avoid detection and aposematism to advertise unprofitability—but we lack understanding of how ecological context favors one strategy over the other. We conducted a globally replicated predation experiment at 21 sites on six continents to test how predator community, prey community, and visual environment influenced the predation risk of 15,018 artificial paper “moth” prey with cryptic or warning coloration. Results indicated that aposematic strategies fare better in environments with low predation intensity, whereas camouflage strategies are advantaged when other camouflaged prey species are rare and when light levels are low. This study demonstrates how multiple mechanisms shape antipredator strategies, helping to explain the evolution and global distribution of camouflaged and aposematic animals.

昆虫抗捕食者配色的全局选择

自然选择一再导致进化出两种对抗捕食者的颜色策略——伪装以避免被发现，警示以宣传无利可图——但我们缺乏对生态环境如何偏爱其中一种策略的理解。在全球6大洲21个地点进行了捕食实验，研究了捕食者群落、被捕食者群落和视觉环境对15018只具有隐色或警告色的人造纸“蛾”捕食风险的影响。结果表明，在捕食强度较低的环境中，警示性策略效果较好，而在其他被伪装的猎物较少和光照较低的环境中，伪装策略效果较好。这项研究展示了多种机制如何形成反捕食者策略，有助于解释伪装和警告动物的进化和全球分布。

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.
