背景与目的花的颜色在传粉者的吸引和决策中起着重要作用。不同的传粉者功能群倾向于选择不同的花色，因此可能导致不同群落之间不同的花色组成，这取决于优势传粉者的视觉系统。方法对106株日本高山植物和96株新西兰高山植物在300~700 nm波长范围内的花卉光谱反射率进行了测量。根据蜜蜂和苍蝇的颜色视觉模型以及主成分分析，考虑到植物物种之间的系统发育非独立性，花的颜色似乎随着传粉者类型的不同而不同。因此，不同地区的花色组成不同，反映了日本的蜜蜂和苍蝇混合授粉动物和新西兰以苍蝇为主的授粉动物。根据蜜蜂的色觉模型，膜翅目授粉的花的大部分颜色似乎是由蜜蜂辨别出来的。结论日本和新西兰高山群落花色组成的差异是由于群落中传粉者区系的差异，而不是地理区域和群落系统发育的非生物因素的差异。
Background and AimsFlower colour plays a major role in the attraction and decision-making of pollinators. Different functional groups of pollinators tend to prefer different flower colours, and therefor may lead to different flower colour compositions among different communities depending on the visual system of the dominant pollinators. However, few studies have investigated the linkage between pollinator fauna and flower colour composition in natural communities, a theme we explored in the present study.MethodsFlower spectral reflectance of 106 Japanese and 96 New Zealand alpine plants in the wavelength range 300–700 nm were measured. The composition of pollinator fauna in the communities and the types of pollinators for each plant species were also investigated.Key ResultsBased on bee and fly colour vision models, as well as a principal components analysis, considering phylogenetic non-independence between plant species, flower colours appeared to vary according to pollinator type rather than geographical region. Consequently, flower colour composition differed between the regions, reflecting the bee/fly mixed pollinator fauna of Japan and the fly-dominant pollinator fauna of New Zealand. According to the bee colour vision model, the majority of the colours of hymenopteran-pollinated flowers appeared to be discriminated by bees. In contrast, many of the colours of dipteran-pollinated flowers would not be discriminated by bees and flies.ConclusionThe results suggest that the differences in flower colour composition between Japanese and New Zealand alpine communities are due to differences in the pollinator fauna in these communities rather than differences in abiotic factors between the geographical regions and the phylogenetic origin of the communities.
