Ecological communities are organized in trophic levels that share manifold interactions forming complex food webs. Infochemicals can further modify these interactions, e.g., by inducing defenses in prey. The micro-crustacean is able to respond to predator-specific chemical cues indicating an increased predation risk. shows plastic responses by adapting its morphology, behavior, and physiology, increasing organism, and population fitness. This stabilizes community structures. This review will describe the progress that has been made in understanding the high degree of plasticity observed in the model crustacean . I summarize current knowledge on the processes of predator detection, ranging from the nature of biologically active chemical cues to the underlying neurophysiological mechanisms. With this, I aim to provide a comprehensive overview on the molecular mechanisms of environmental phenotypic adaptation. In times of climate change and pollution understanding information transfer in aquatic systems is valuable as it will allow us to predict whether and how community structures are being affected.
生态群落按营养级组织，这些营养级共享多种相互作用，形成复杂的食物网。信息化学物质可以进一步改变这些相互作用，例如通过诱导猎物产生防御反应。微型甲壳动物能够对表明捕食风险增加的捕食者特异性化学信号做出反应。它通过改变其形态、行为和生理表现出可塑性反应，提高个体和种群的适应性。这稳定了群落结构。本综述将描述在理解模式甲壳动物中观察到的高度可塑性方面所取得的进展。我总结了目前关于捕食者检测过程的知识，从生物活性化学信号的性质到潜在的神经生理机制。借此，我旨在全面概述其环境表型适应的分子机制。在气候变化和污染的时代，了解水生系统中的信息传递很有价值，因为这将使我们能够预测群落结构是否以及如何受到影响。
