化学信号介导水生生物的许多关键生命过程，如摄食、繁殖和底栖沉降。根据流体速度和流动状态，释放的化学物质在生物体接收之前通过扩散、层流平流或湍流平流进行运输。在这里，我们审查运输机制和生态后果，在每个制度。我们讨论线索结构的浓度梯度，浓度波动和空间模式，并得出结论的策略，动物用来获取信息。在某些情况下，化学品的迁移是通过多种机制的组合发生的，这就需要进行多尺度分析。机制和缩放是最近研究中出现的主要主题。特别是，结合联合收割机生物和物理变量的无量纲参数揭示了生物体对化学线索作出反应的一般原则，并有助于定义行为机制。
Chemical cues mediate many critical life processes, such as feeding, reproduction, and benthic settling, for aquatic organisms. Depending on the fluid velocity and flow regime, released chemicals are transported via diffusion, laminar advection, or turbulent advection prior to organism reception. Here, we review transport mechanisms and ecological consequences in each regime. We discuss cue structures in terms of concentration gradients, concentration fluctuations, and spatial patterns and draw conclusions about strategies that animals use to acquire information. In some cases, chemical transport occurs through a combination of mechanisms, which requires a multiscale analysis. Regime and scaling are major themes that emerge from recent research. In particular, nondimensional parameters that combine biological and physical variables reveal general principles under which organisms respond to chemical cues and facilitate defining regimes of behavior.
