动物会根据被捕食的风险改变觅食行为。我们使用圆网蜘蛛 Argiope keyerlingi 测试了这个想法。我们在捕食性螳螂 Pseudomantis albofimbriata 存在的情况下，根据网的大小和丝质装饰的大小来测量蜘蛛的觅食投入。然而，没有有限的证据表明 A. keyerlingi 会改变其装饰行为，也没有证据表明这种蜘蛛会改变其网络结构以应对螳螂捕食者的存在。我们认为这些蜘蛛可能会使用多种线索来评估捕食压力，并且根据过去的经验，它们对捕食者的反应有所不同。
Animals are expected to alter their foraging behaviour depending on the risk of predation. We tested this idea using the orb-web spider Argiope keyserlingi. We measured the foraging investment of spiders in terms of web size and size of silk decorations in the presence of a predatory praying mantid, Pseudomantis albofimbriata. However, no limited evidence that A. keyserlingi alters its decorating behaviour and no evidence that this spider alters its web architecture in response to the presence of a mantid predator. We suggest that these spiders may use multiple cues to assess predation pressure and that they respond differently to predators based on past experience.
