管理外来入侵物种在海洋中特别具有挑战性，主要是因为海洋生态系统在广泛的空间尺度上高度相连。只有及早发现物种，管理部门迅速作出反应，才能消灭海洋入侵物种。目前缺乏可在整个海洋区域转移的通用方法来确定控制入侵种群的优先行动。在这里，专家的知识，引发优先11个管理行动，控制12个模式物种，区分的差异，分散能力，分布在该地区的管理，和分类身份。每一项行动都使用五个标准（有效性、可行性、可接受性、对土著社区的影响和成本）进行评估，这些标准结合在一个“适用性”指标中。提高公众认识和鼓励对入侵物种的商业利用被列为高度优先事项，而生物控制行动被认为是最不适用的。我们的研究结果可以指导快速决策，优先考虑控制入侵物种的管理方案，特别是在入侵的早期阶段，减少管理人员的响应时间是至关重要的。(C)2019作者由爱思唯尔公司出版
Managing invasive alien species is particularly challenging in the ocean mainly because marine ecosystems are highly connected across broad spatial scales. Eradication of marine invasive species has only been achieved when species were detected early, and management responded rapidly. Generalized approaches, transferable across marine regions, for prioritizing actions to control invasive populations are currently lacking. Here, expert knowledge was elicited to prioritize 11 management actions for controlling 12 model species, distinguished by differences in dispersion capacity, distribution in the area to be managed, and taxonomic identity. Each action was assessed using five criteria (effectiveness, feasibility, acceptability, impacts on native communities, and cost), which were combined in an 'applicability' metric. Raising public awareness and encouraging the commercial use of invasive species were highly prioritized, whereas biological control actions were considered the least applicable. Our findings can guide rapid decision-making on prioritizing management options for the control of invasive species especially at early stages of invasion, when reducing managers' response time is critical.
