生物相互作用在生物多样性的组织和持续中起着重要作用。景观结构的非自然变化，如栖息地丧失和破碎化，可能使种群孤立，破坏生物群落，影响物种生存，改变植物与传粉媒介之间的复杂关系。植物-传粉者相互作用网络具有不对称性和巢性等特征，这些特征可能会影响网络对景观变化的稳定性和鲁棒性。共生网络中的物种可能对景观变化做出反应，在临界栖息地破坏阈值处突然崩溃。在这项工作中，我们回顾了有关景观变化对植物传粉媒介网络影响的科学文献的一般趋势。为此，2011年5月在Scopus和Web of Knowledge数据库中进行了一项调查，使用了“传粉昆虫*”与“景观”、“栖息地丧失”和“网络”这三个术语的所有七种可能组合。在155篇论文中，92%的论文显示景观变化对传粉媒介多样性和植物繁殖成功率有显著影响。在所有被分析的论文中，约有50%显示了农业集约化对植物-传粉者相互作用的影响，这是由于自然区域转化为农作物的增加造成的。景观改变影响了异花授粉和植物有性生殖，主要原因是由于生境隔离加剧以及剩余可用生境中的花卉资源和筑巢区减少，传粉媒介的多样性和可用性降低。综合研究景观改造对自然生态系统的影响，以及这些变化如何影响传粉网络的稳定性和鲁棒性，对保护植物-传粉媒介的相互作用非常有用，对保护自然和农业生态系统中的植物、传粉媒介和传粉服务具有积极的总体影响。(C) 2012 Elsevier Ltd.版权所有。
Biotic interactions play an important role on the organization and persistence of biodiversity. Unnatural modifications of landscape structure such as habitat loss and fragmentation can isolate populations and disrupt biological communities, affecting species survival and altering the complex set of relationships between plants and pollinators. Plant-pollinator interaction networks have characteristics such asymmetry and nestedness that may influence the stability and robustness of networks to landscape changes. Species in mutualistic networks might respond to landscape modifications with a sudden collapse at critical habitat destruction thresholds. In this work we review general trends in the scientific literature related to the effects of landscape changes on plant-pollinator networks. For this, a survey in Scopus and Web of Knowledge databases was conducted in May 2011 using all seven possible combinations of the terms "pollinat*" with the terms "landscape", "habitat loss" and "network". We found 155 papers and 92% of those showed significant effects of landscape changes on pollinator diversity and plant reproductive success. Approximately 50% of all analyzed papers showed effects of agriculture intensification as a result of increases in the conversion of natural areas into agricultural crops on plant-pollinator interactions. Landscape modifications affected cross-pollination and the sexual reproduction of plants largely because of reduced diversity and availability of pollinators due to increased habitat isolation and reduction of floral resources and nesting areas in the remaining available habitat. An integrated approach concerning the effects of modified landscapes on natural ecosystems regarding how these variations can affect the stability and robustness of pollination networks can be extremely useful for conservation of plant-pollinators interactions, with positive overall consequences for conservation of plant, pollinators and pollination services in natural and agricultural ecosystems.
