尽管人们普遍关注授粉服务的下降，但对大多数传粉者组合的变化模式知之甚少。通过研究英国和荷兰的蜜蜂和食蚜蝇群落，我们发现了这两个国家当地蜜蜂多样性下降（1980年前后）的证据;然而，食蚜蝇中观察到了不同的趋势。根据组合和位置，传粉下降是最常见的栖息地和花卉专家，在univoltine物种，和/或在nonmigrants。与此同时，依赖于传粉者数量下降的异交植物物种本身相对于其他植物物种也有所下降。总之，这些研究结果强烈表明，功能相关的植物和传粉者物种的地方保护之间的因果关系。
Despite widespread concern about declines in pollination services, little is known about the patterns of change in most pollinator assemblages. By studying bee and hoverfly assemblages in Britain and the Netherlands, we found evidence of declines (pre- versus post-1980) in local bee diversity in both countries; however, divergent trends were observed in hoverflies. Depending on the assemblage and location, pollinator declines were most frequent in habitat and flower specialists, in univoltine species, and/or in nonmigrants. In conjunction with this evidence, outcrossing plant species that are reliant on the declining pollinators have themselves declined relative to other plant species. Taken together, these findings strongly suggest a causal connection between local extinctions of functionally linked plant and pollinator species.
