摘要

描述了12种蜉蝣科植物的底物关联和纵向分布。栖息地专门化似乎是这个科内适应性辐射的主要手段。所有物种都表现出对可用生境的限制性利用:砂砾、鹅卵石、巨石或苔藓。在某种程度上，纵向分布的模式可能是物种对不同底物表现出特异性的结果。

Substrate Associations and Longitudinal Distributions in Species of Ephemerellidae (Ephemeroptera:Insecta) from Western Oregon

Substrate associations and longitudinal distributions are described for 12 species of Ephemerellidae. Habitat specialization seems to have been a major means of adaptive radiation within this family. All species showed restrictive use of available habitats: sand-gravel, cobble, boulder, or moss. Patterns of longitudinal distribution may be, in part, a consequence of the specificity that species show for different substrates.
