Functional trait–based mediation of animal invasions is only now developing, yet it is already showing as much promise as the approach has for plant invasion biology. Here, we provide a theory-founded examination of functional trait–based ecology with respect to animal invasions, together with a review of the empirical research. Recent developments in the scaling of traits to ecosystems, along with the frameworks for invasion ecology, provide a powerful foundation for investigations. Despite growing empirical research in this field, interspecific comparisons incorporating comparative phylogenetic approaches remain uncommon, and those examining assemblages are even more so. Despite the importance of time since introduction, it is rarely included in studies. Broad environmental tolerances, life history traits associated with fast growth or greater reproduction, and in some cases, greater phenotypic plasticity of traits, mediate the success of animal alien species at various stages of invasion, although introduction effort remains one of the most important factors affecting success.

动物入侵途径的功能特征变化

基于功能性状的动物入侵介导目前才刚刚发展起来，但它已经显示出与植物入侵生物学方法一样多的前景。在这里，我们对动物入侵方面基于功能性状的生态学进行了基于理论的检验，并对实证研究进行了回顾。生态系统特征规模的最新发展以及入侵生态学框架为研究提供了强有力的基础。尽管该领域的实证研究不断增长，但结合比较系统发育方法的种间比较仍然不常见，而那些检查组合的情况更是如此。尽管自引入以来的时间很重要，但它很少被纳入研究中。广泛的环境耐受性、与快速生长或更多繁殖相关的生活史特征，以及在某些情况下，特征的更大表型可塑性，介导了外来动物物种在入侵的各个阶段的成功，尽管引入努力仍然是影响的最重要因素之一成功。
