Marine prey and predators will respond to future climate through physiological and behavioral adjustments. However, our understanding of how such direct effects may shift the outcome of predator–prey interactions is still limited. Here, we investigate the effects of ocean warming and acidification on foraging behavior and biomass of a common prey (shrimps, Palaemon spp.) tested in large mesocosms harboring natural resources and habitats. Acidification did not alter foraging behavior in prey. Under warming, however, prey showed riskier behavior by foraging more actively and for longer time periods, even in the presence of a live predator. No effects of longer-term exposure to climate stressors were detected on prey biomass. Our findings suggest that ocean warming may increase the availability of some prey to predators via a behavioral pathway (i.e., increased risk-taking by prey), likely by elevating metabolic demand of prey species.

海洋变暖通过冒险行为增加了甲壳类猎物的供应

海洋猎物和捕食者将通过生理和行为调整来应对未来的气候。但是，我们对这种直接影响如何改变捕食者与猎物互动结果的理解仍然有限。在这里，我们调查了海洋变暖和酸化对在具有自然资源和栖息地的大型中型宇宙动物中测试的常见猎物（虾，Palaemon spp。）的觅食行为和生物量的影响。酸化不会改变猎物的觅食行为。然而，在变暖的情况下，即使有活着的捕食者，猎物也会通过更积极地觅食和更长的时间来表现出较高的危险行为。没有发现长期暴露于气候胁迫对猎物生物量的影响。我们的发现表明，海洋变暖可能会通过行为途径（例如，
