入侵生态学在确定可能决定生物入侵成败的特定机制方面取得了相当大的进展。越来越多的人正在努力将越来越多的假说相互联系甚至综合起来，以便对入侵有一个更全面和综合的理解。我们认为，从生态进化的角度看待入侵是实现这种整合的一种有希望的方法。它强调入侵的进化前因，即物种的进化遗产及其在塑造因入侵而产生的新生物相互作用中的作用。我们提出了一个概念框架，包括五个假设的情况下，所谓的“生态进化经验”的影响，在居民本地和入侵的非本地物种的入侵成功，这取决于生态相互作用的类型（捕食，竞争，互惠互利，和共生）。我们发现，几个主要的生态入侵假说，包括“敌人释放”，“EICA”，“新的武器”，“天真的猎物”，“新协会”，“错过互惠"和”达尔文的归化假说“可以整合到这个框架中，通过揭示他们共同的隐含参考的概念，生态进化的经验。我们起草了一个例行的本地和非本地物种的生态进化经验的评估，使用基于食物网的例子，并提出了两个指数（xp焦点指数和xp居民指数）的实际量化的生态进化经验。我们的研究强调了生态进化观点对生物入侵的解释潜力。
Invasion ecology has made considerable progress in identifying specific mechanisms that potentially determine success and failure of biological invasions. Increasingly, efforts are being made to interrelate or even synthesize the growing number of hypotheses in order to gain a more comprehensive and integrative understanding of invasions. We argue that adopting an eco-evolutionary perspective on invasions is a promising approach to achieve such integration. It emphasizes the evolutionary antecedents of invasions, i.e. the species’ evolutionary legacy and its role in shaping novel biotic interactions that arise due to invasions. We present a conceptual framework consisting of five hypothetical scenarios about the influence of so-called ‘eco-evolutionary experience’ in resident native and invading non-native species on invasion success, depending on the type of ecological interaction (predation, competition, mutualism, and commensalism). We show that several major ecological invasion hypotheses, including ‘enemy release’, ‘EICA’, ‘novel weapons’, ‘naive prey’, ‘new associations’, ‘missed mutualisms’ and ‘Darwin’s naturalization hypothesis’ can be integrated into this framework by uncovering their shared implicit reference to the concept of eco-evolutionary experience. We draft a routine for the assessment of eco-evolutionary experience in native and non-native species using a food web-based example and propose two indices (xp Focal index and xp Residents index) for the actual quantification of eco-evolutionary experience. Our study emphasizes the explanatory potential of an eco-evolutionary perspective on biological invasions.
