虽然近年来环境DNA（eDNA）元条码调查显示出很大的希望作为一种替代监测方法，整合到现有的海洋监测计划可能会混淆的eDNA信号的分散。海流和潮汐的影响可能会将eDNA远距离运输，导致物种检测出现假阳性，导致生物多样性评估不准确，最终导致海洋环境管理不善。在这项研究中，我们确定了eDNA元条形码调查的能力，以区分从四个海洋栖息地在一个小的空间尺度（
While in recent years environmental DNA (eDNA) metabarcoding surveys have shown great promise as an alternative monitoring method, the integration into existing marine monitoring programs may be confounded by the dispersal of the eDNA signal. Currents and tidal influences could transport eDNA over great distances, inducing false-positive species detection, leading to inaccurate biodiversity assessments and, ultimately, mismanagement of marine environments. In this study, we determined the ability of eDNA metabarcoding surveys to distinguish localized signals obtained from four marine habitats within a small spatial scale (
