为什么有些生物在进入新的区域后会变得具有侵略性，而另一些生物甚至无法建立，这是生态学中的一个基本问题。成功的障碍预计将在入侵途径的沿着每个阶段过滤物种。然而，迄今为止还没有研究调查物种性状如何与任何群体中从引进到大空间尺度传播的成功相关联。使用全球范围内最大的哺乳动物引进数据集和最近开发的系统发育比较方法，我们表明，人类介导的引进大大偏向哪些物种有机会成为入侵者，因为繁殖寿命较长的高产哺乳动物更有可能被引入。随后，更大的繁殖产量和更高的引进努力与成功的建立和传播阶段。因此，高生产力支持人口增长和入侵的成功，在每个入侵阶段过滤物种的屏障，逐步更大的繁殖力。
Why some organisms become invasive when introduced into novel regions while others fail to even establish is a fundamental question in ecology. Barriers to success are expected to filter species at each stage along the invasion pathway. No study to date, however, has investigated how species traits associate with success from introduction to spread at a large spatial scale in any group. Using the largest data set of mammalian introductions at the global scale and recently developed phylogenetic comparative methods, we show that human‐mediated introductions considerably bias which species have the opportunity to become invasive, as highly productive mammals with longer reproductive lifespans are far more likely to be introduced. Subsequently, greater reproductive output and higher introduction effort are associated with success at both the establishment and spread stages. High productivity thus supports population growth and invasion success, with barriers at each invasion stage filtering species with progressively greater fecundity.
