入侵物种以及随之而来的世界生物群同质化形成了一个全球性问题，其后果从本地物种的减少和灭绝到对人类健康的威胁。这个问题的严重性要求我们彻底了解入侵过程，它包括三个主要阶段：初始分散、建立自我维持的种群和扩散。为了评估研究工作在这些阶段的相对分布，我们对过去10年发表在23个主要期刊上的873篇文章进行了文献综述。在873篇论文中，只有96篇（11.0%）研究了初始扩散，其中只有一半（6.2%）是经验性的。作为偶然过程的第一个阶段，我们认为初始分散是指导管理工作的最佳阶段。此外，初始扩散与群落聚集和元群落动态等基本生态问题直接相关。到目前为止，回答这些问题和防止入侵是生态学家的目标，这里提到的研究努力的差异表明生态学家需要扩大他们的努力，包括更多的研究最初的扩散。
Invasive species, and the ensuing homogenization of the world's biota, form a global problem with consequences ranging from the decline and extirpation of native species to threats to human health. The magnitude of this issue demands a thorough understanding of the invasion process, which consists of three main stages: initial dispersal, establishment of self-sustaining populations, and spread. To assess the relative distribution of research effort among these stages, we conducted a literature review using 873 articles published in 23 major journals over the past 10 years. Of the 873 papers, only 96 (11.0%) studied initial dispersal, and only half of these (6.2% of the total) were empirical. As the first stage in a contingent process, we argue that initial dispersal is the best stage during which to direct management efforts. In addition, initial dispersal has direct relevance for fundamental ecological questions regarding community assembly and metacommunity dynamics. In so far that answering these questions and preventing invasion are goals of ecologists, the disparity in research effort noted here suggests that ecologists need to expand their efforts to include more research on initial dispersal.
