明尼苏达州路边熊蜂和蝴蝶的多样性取决于花的多样性和丰度，而不取决于花的原生状态

栖息地的丧失是导致许多昆虫迅速减少的重要原因。路边栖息地的恢复被认为是支持大黄蜂和蝴蝶这两种受保护昆虫群落的机会。然而，目前还不清楚目前的路边恢复方法如何转化为传粉昆虫的丰度和多样性。在此，我们询问了播种了本地和非本地混合种子的路边植物群落在种植 2-20 年后对熊蜂和蝴蝶群落的影响。我们发现，熊蜂和蝴蝶的丰度和多样性与花的丰度和多样性呈正相关。然而，在种植了多种本地混合种子的地块中，传粉昆虫群落与种植了物种贫乏的非本地混合种子的地块中的传粉昆虫群落并无不同，这可能是因为本地混合种子中的许多草本植物难以成活，而且所有地块都很容易被从未种植过的物种定殖。虽然有更多本地花卉的地块并不一定支持更高的授粉者多样性，但我们确实发现了几种在路边生长良好并支持授粉者的本地植物，包括金鱼草（Solidago spp.）、牛奶草（Asclepias spp.）和野生佛手柑（Monarda fistulosa）。我们的数据表明，管理一个更加多样和丰富的花卉群落将有利于熊蜂和蝴蝶。完善本地混合种子的组成，在非本地混合种子中加入更多丰富的花卉，并对本地植物群落的管理进行投资，可以提高路边授粉者群落的栖息地价值。
