摘要:了解外来入侵物种(alien invasive species,AIS)的生物学涉及纯生物学及应用生物学的问题。但是靠预先设计的实验来加深人们的了解显然是不可能的。然而我们可以研究现有的入侵,这也是一个很好的途径。本文利用新西兰历史上的一些记录,探讨了物种在新环境中成功定居的因素。令人惊奇的是,物种间的生物学差异对成功的定居几乎没有什么作用,相反,真正起作用的是一个物种被引入新环境的频率及数量。

Understanding the biology of alien invasive species (AIS) is a problem for pure, as well as applied biology. However, it is obviously not possible to conduct designed experiments to further our understanding. We can, however, study actual invasions; the next best thing. We used historical data from New Zealand to explore the correlates of successful establishment of species in a new environment. Surprisingly, biological differences between species explained little of the variation in establishment success. Instead, what matters is how often, and in what numbers, a species is introduced into the new environment.
