The success of alien plants in novel environments questions basic assumptions about the fate of native species under climate change. Aliens generally spread faster than the velocity of climate change, display considerable phenotypic plasticity as well as adaptation to new selection pressures, and their ranges are often shaped by biotic rather than climatic factors. Given that many native species also exhibit these attributes, their risk of extinction as a result of climate change might be overestimated.
外来植物在新环境中的成功对有关气候变化下本地物种命运的基本假设提出了质疑。外来物种的传播速度通常比气候变化的速度快，表现出相当大的表型可塑性以及对新选择压力的适应能力，而且它们的分布范围通常受生物因素而不是气候因素的影响。鉴于许多本地物种也具有这些特征，它们因气候变化而灭绝的风险可能被高估了。
