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.
近几十年来，越来越多的研究探讨了生物入侵中生态与进化概念之间的联系。这些联系对于理解入侵者成功背后的过程可能至关重要。然而，科学家在入侵植物生态与进化整合方面的研究程度记录甚少，因为在入侵生物学研究中很少有人尝试评估这些努力。这样的分析有助于识别有充分记录的关系，并找出我们知识中的空白。在本研究中，我们使用基于网络的方法来可视化基础研究文献中生态与进化主要方面之间的联系。以禾本科为例，我们表明生态概念比进化概念得到了更多研究且联系更紧密。一些可能的联系根本没有记录，这代表了入侵者生态与进化之间的知识空白。在知识空白中，可塑性、基因流、表观遗传学和人类影响等概念的联系尤为不足。我们讨论了五条可能的研究途径，以更好地理解禾本科以及一般外来植物成功过程中生态与进化之间的关系。
