Alien species successfully colonize new ranges if they encounter favourable environmental conditions there and possess traits that match new challenges. Climate‐matching approaches comparing native and exotic ranges mostly consider temperature and precipitation niches of alien species, but have largely ignored UV‐B radiation. UV‐B fundamentally differs between hemispheres, with much higher levels at southern than at northern latitudes. Consequently, UV‐B might act at the global scale and present a so far neglected filter that species need to overcome when invading high‐UV‐B environments.

本地分布特征而不是功能特征解释了入侵物种对高UV-B环境的预先适应

如果外来物种在当地遇到有利的环境条件并具有与新挑战相匹配的性状，则它们可以成功地在新范围内定居。比较本地和外来范围的气候匹配方法主要考虑外来物种的温度和降水位，但很大程度上忽略了UV-B辐射。半球之间的UV-B根本不同，南部的水平比北部的纬度高得多。因此，UV-B可能在全球范围内发挥作用，并提供了一种迄今为止被忽略的过滤器，当入侵高UV-B环境时，物种需要克服。
