In New-Zealand alpine ecosystems, social bees are completely lacking and flies are major pollinators for most alpine plants. Flowering overlaps among species were large and flowering patterns of individual species were unclear in NZ alpine communities in comparison with Japanese alpine ecosystems in which social bees are major pollinators. Because foraging activity of flies did not show clear seasonal trend due to their opportunistic lifecycle, natural selection on flowering phenology might be not strong in NZ ecosystems. Furthermore, diversities of floral morphology and color were significantly lower in NZ alpine ecosystems. These results indicate that absence of social bees might cause different selective forces in floral evolution in NZ alpine ecosystems.

在纽西兰高山生态系统中，社会蜜蜂完全缺乏，苍蝇是大多数高山植物的主要传粉媒介。与日本高山生态系统相比，NZ Alpine社区中的单个物种的开花重叠是大型物种的大开花模式，而社会蜜蜂是主要的授粉者。由于苍蝇的觅食活动并未显示出由于机会性生命周期而显示出明显的季节性趋势，因此在新西兰生态系统中，自然选择的果落选择可能并不强。此外，在NZ Alpine生态系统中，花卉形态和颜色的多样性显着降低。这些结果表明，在NZ Alpine生态系统中，缺乏社会蜜蜂可能会导致不同的选择性力。
