水生生物可能使用不同的机制来定位气味源，包括气味门控趋流性和趋化性。然而，气味信号中包含的空间和时间信息在引导方向中的作用正在争论中。在自然界中，湍流和羽流蜿蜒产生信号不稳定性，生物必须克服这种不稳定性才能成功定位气味源。在这项研究中，小龙虾提出了由连续释放的射流或脉冲射流范围从0.5到3 Hz的气味羽流。小龙虾定向显着不同的脉冲气味羽显着不同，比在连续释放的喷气羽。在连续的气味羽流中，小龙虾走得更快，有更准确的航向和转向角度，而且停下来的次数更少。结果表明，小龙虾能够在脉冲气味羽流中定向，但连续释放的气味羽流的空间和时间复杂性使它们能够更成功地找到气味源。
Aquatic organisms may use different mechanisms to locate an odour source, including odour-gated rheotaxis and chemotaxis. However, the effects of spatial and temporal information contained within odour signals in guiding orientation are under debate. In nature, turbulence and plume meandering give rise to signal intermittency, which organisms must overcome to locate an odour source successfully. In this study, crayfish were presented with odour plumes formed by a continuously released jet or a pulsed jet ranging from 0.5 to 3 Hz. Crayfish oriented significantly differently in pulsed odour plumes differed significantly from than in a continuously released jet plume. In a continuous odour plumes, crayfish walked faster, had more accurate heading and turning angles, and stopped less often. The results suggest that crayfish are able to orient in a pulsed odour plumes, but that the spatial and temporal complexity of a continuous released odour plume allowed them to be more successful to find the odour source.
