尽管人们普遍关注传粉媒介的命运及其提供的生态系统服务，但关于传粉媒介数量下降的程度及其对作物授粉和粮食安全的实际贡献，我们仍然拥有令人惊讶的稀缺科学数据。我们使用最近发表的数据从北美东北部表明，在本地和区域尺度的研究需要了解传粉者下降，物种特异性的全球变化的反应是广泛一致的跨尺度。其次，我们发现，目前提供大部分生态系统服务（即作物授粉）的蜜蜂物种并没有出现下降趋势，而是在人类主导的景观中茁壮成长。
Despite the widespread concern about the fate of pollinators and the ecosystem services they deliver, we still have surprisingly scarce scientific data on the magnitude of pollinator declines and its actual contribution to crop pollination and food security. We use recently published data from northeastern North America to show that studies at both the local and regional scales are needed to understand pollinator declines, and that species-specific responses to global change are broadly consistent across scales. Second, we show that bee species that are currently delivering most of the ecosystem services (i.e. crop pollination) are not among the species showing declining trends, but rather appear to thrive in human-dominated landscapes.
