Early detection and rapid response represent cornerstones of effective management of biological invasions, and development of methods that increase the sensitivity and efficiency of species detection directly benefit such efforts.We compared environmental DNA (eDNA) and canine scent detection of Dreissena polymorpha (Pallas, 1771), the Eurasian zebra mussel, in lakes of central Texas, USA.Environmental DNA analysis has become routinely incorporated as a component of D. polymorpha management programs; however, canine scent detection has typically been limited to inspection for adult mussels on watercraft.Thus, our work represents the first attempt to evaluate detection of D. polymorpha veligers (i.e., free-swimming larval stages) and other microscopic traces in environmental samples with canine scent detection.The specific objectives of this study were to: 1) evaluate whether canines can detect D. polymorpha in environmental samples; 2) quantify and compare limits of detection of canine scent detection and eDNA analysis; and 3) assess the performance of detection technologies through blind screening of ten lakes.In order of objective, our major findings include: 1) canines can be trained to detect D. polymorpha veligers in water samples; 2) eDNA detection is 2-100x more sensitive than canine scent detection; and 3) canine scent detection and eDNA both appear to outperform microscopy for D. polymorpha detection in environmental water samples.However, more work is needed to understand the conditions dictating when canine scent detection or eDNA outperforms the other.

Management of Biological Invasions

生物入侵管理由 ELIAS DANA 博士于 2010 年创立，是一本开放获取、同行评审的国际期刊，专注于世界各地水生和陆地生态系统生物入侵的应用研究。该杂志致力于弥合科学研究与科学在入侵物种引入和生物多样性保护领域的决策、监管和管理中的应用之间的差距。管理生物入侵是一门危机科学，生物入侵管理旨在提供对问题的见解，记录新的检测、测量和分析形式，并记录该问题的切实解决方案。以及相关国际会议的议事录。作为鼓励对国家和国际重要事项进行知情讨论的平台，我们发表观点论文，突出新出现的问题、展示倡议并提出领先研究人员的意见。

Management of Biological Invasions, founded by Dr. ELIAS DANA in 2010, is an open-access, peer-reviewed international journal that focuses on applied research on biological invasions in aquatic and terrestrial ecosystems worldwide. The journal aims to bridge the gap between scientific research and its application in decision-making, regulation, and management concerning the introduction of invasive species and biodiversity conservation. Biological invasion management is a crisis science that seeks to provide insights into the issues at hand, document new forms of detection, measurement, and analysis, and record practical solutions to these problems. Additionally, we publish proceedings from relevant international conferences. As a platform for encouraging informed discussions on national and international important matters, we publish opinion papers that highlight emerging issues, showcase initiatives, and present the views of leading researchers.
