寄生虫入侵被认为是对生物多样性、经济和粮食生产的重大威胁，但在减轻这些潜在影响方面存在重大挑战。对寄生虫多样性的报道严重不足，而且很少及早发现入侵并进行有效干预。在本章中，我们重点讨论了入侵寄生虫的生物学特性：可测量的形态、生理和行为属性，以及介导入侵的其他系统发育、分布和宿主范围因素。我们将寄生虫的生物学特征映射到现有的生物入侵框架上，重点关注每个入侵阶段（引入、建立和随后的传播和影响）。为了促进入侵寄生虫威胁的早期识别和优先排序，我们引入了一个概念框架来理解入侵寄生虫的影响，并产生假设来测试非随机、可预测的潜在入侵者子集是否能够成功克服入侵阶段之间的障碍。
Parasite invasions are recognized as a major threat to biodiversity, economies and food production, but there are significant challenges to mitigating these potential impacts. Parasite diversity is severely under-reported and invasions are rarely detected early enough for effective intervention. In this chapter, we focus on the bio-characteristics of invasive parasites: the measurable morphological, physiological and behavioural attributes, and additional phylogenetic, distributional and host range factors that mediate invasions. We map parasite bio-characteristics onto existing biological invasion frameworks focusing on each invasion stage (introduction, establishment and subsequent spread and impact). To promote the earlier identification and prioritization of threats from invasive parasites, we introduce a conceptual framework to understand the impacts of invasive parasites and to generate hypotheses for testing whether a non-random, predictable, subset of potential invaders are successful in overcoming the barriers between invasion stages.
