近几十年来，越来越多的研究解决了生物入侵中生态和进化概念之间的联系。这些联系可能对理解入侵者成功背后的过程至关重要。然而，科学家们在入侵植物的生态学和进化的整合方面所做的工作很少有文献记载，因为很少有人尝试在入侵生物学研究中评估这些努力。这样的分析可以帮助我们认识到记录良好的关系，并找出我们知识中的空白。在这项研究中，我们使用了一种基于网络的方法来可视化主要研究文献中生态学和进化主要方面之间的联系。以禾本科为例，我们发现生态概念比进化概念得到了更多的研究和更好的联系。一些可能的联系根本没有被记录下来，这代表了生态和进化之间的知识差距。在知识缺口中，可塑性、基因流、表观遗传学和人类影响的概念联系尤其不足。我们讨论了五种可能的研究途径，以更好地理解生态学和进化在禾本科和一般外来植物成功中的关系。
In recent decades, a growing number of studies have addressed connections between ecological and evolutionary concepts in biologic invasions. These connections may be crucial for understanding the processes underlying invaders’ success. However, the extent to which scientists have worked on the integration of the ecology and evolution of invasive plants is poorly documented, as few attempts have been made to evaluate these efforts in invasion biology research. Such analysis can facilitate recognize well-documented relationships and identify gaps in our knowledge. In this study, we used a network-based method for visualizing the connections between major aspects of ecology and evolution in the primary research literature. Using the family Poaceae as an example, we show that ecological concepts were more studied and better interconnected than were evolutionary concepts. Several possible connections were not documented at all, representing knowledge gaps between ecology and evolution of invaders. Among knowledge gaps, the concepts of plasticity, gene flow, epigenetics and human influence were particularly under-connected. We discuss five possible research avenues to better understand the relationships between ecology and evolution in the success of Poaceae, and of alien plants in general.
