许多被捕食物种可以调整形态，以减少捕食风险的捕食线索。增强猎物防御利用捕食者线索可能会提高种植物种的生存和加强物种恢复的努力，但在工业相关的规模，这种好处的评估是必要的。我们研究了如何提高一个模型的基础物种，牡蛎（Crassostrea virginica），在商业孵化条件下，从两个常见的捕食者物种的线索，可以提高生存在各种捕食者制度和环境条件。牡蛎对捕食者的反应是长出比对照更结实的壳，但根据捕食者的种类，壳的特征有细微的变化。捕食者引起的变化显着增加牡蛎的生存高达600%，生存率最大化时，线索源与当地捕食者政权相匹配。总的来说，我们的研究结果表明，利用捕食者线索，以提高目标物种的生存跨景观和突出的机会，采用无毒的方法来控制害虫的死亡率。
Many prey species can adjust morphology to reduce predation risk in response to predator cues. Enhancing prey defenses using predator cues may improve survival of cultivated species and enhance species restoration efforts, but assessment of such benefits at industrially relevant scales is needed. We examined how raising a model foundation species, oysters (Crassostrea virginica), under commercial hatchery conditions with cues from two common predator species can improve survival across a variety of predator regimes and environmental conditions. Oysters responded to predators by growing stronger shells than controls, but had subtle variations in shell characteristics depending on the predator species. Predator-induced changes significantly increased oyster survival up to 600% and survivorship was maximized when cue source was matched with local predator regime. Overall, our findings demonstrate the utility of using predator cues to enhance the survival of target species across landscapes and highlight the opportunity to employ nontoxic methods to control pest-based mortality.
