植物和传粉者之间的相互作用网络的研究，使我们能够探索在社区水平上的相互作用模式，检测访问频率的变化和评估网络的嵌套。后者允许更丰富的传粉者物种访问稀有植物物种，可能使社区多样性得以维持，这种方法使得人们有可能在无法获得首选资源时识别物种的重新布线（连接变化）。在这项研究中，拓扑结构，物种身份和重新布线之间的对比，一个在保护区和其他受到持续干扰。这两个网站的网络显着嵌套和共享大量的共同物种的植物和传粉者。然而，这些网站在排他性互动的数量上存在显着差异，这表明互动重新布线的比例很高。引进的蜜蜂物种，意大利蜜蜂，是最常见的物种在这两个网站，也是最相关的相互作用的数量。这是因为它的通才觅食特性使它成为网络核心群体的一部分。总的来说，我们的研究结果强调了在研究网络时了解参与物种的身份的重要性，以及它们之间的连接如何变化，以及栖息地破坏的潜在影响和入侵物种在相互作用重新排列中的作用;所有这些因素都可以对植物传粉网络的功能产生影响。
The study of interaction networks between plants and pollinators allows us to explore interaction patterns at the community level, detect changes in visit frequency and evaluate the nestedness of the networks. The latter allows rare plant species to be visited by more abundant species of pollinators, potentially allowing community diversity to be maintained, and this approach makes it possible to discern the rewiring (changes in connections) of species when their preferred resource is not available. In this study, the topology, species identity and rewiring were compared between two contrasting sites, one within a conservation area and the other subjected to continuous disturbance. The networks of both sites were significantly nested and shared a high number of common species of both plants and pollinators. However, the sites differed notably in the number of exclusive interactions, suggesting a high percentage of interaction rewiring. The introduced bee species, Apis mellifera, was the most frequent species at both sites and also the most connected in terms of the number of its interactions. This is explained by its generalist foraging characteristics that allow it to form part of the networks’ core group. In general, our results underscore the importance of knowing the identity of the participating species when studying networks, and how connections change between them, as well as the potential effect of habitat destruction and the role of invasive species in the rearrangement of the interactions; all factors that can exert an influence on the functioning of plant–pollinator networks.
