| 内容記述 | The heptageniid mayflies Epeorus latifolium and Epeorus l-nigrus are often the dominant species in the upper and midstream areas of Japanese rivers; as such, they play a significant role in river ecosystems. However, although these two species have been identified using the morphological characteristics of the male in its adult stage, it is impossible to differentiate them in their nymphal stage. We conducted a study to elucidate their distribution pattern, i.e., the current distribution of these two species in the Shinano-gawa River basin, based on quantitative field sampling and genetic analysis of nymphs and also some male adults; for these, it was possible to differentiate between the two species reliably. The data collected from the 30 study sites of the 1-year-long study revealed that the E. latifolium and/or E. l-nigrus mayflies are clearly distributed over a very broad area, and they appeared to be the dominant species at about a third of the study sites. Based on our genetic analysis, including several male adult specimens of E. latifolium and E. l-nigrus, it was clearly revealed that E. latifolium and E. l-nigrus respectively form two separate monophyletic clades. That is, E. latifolium and E. l-nigrus are clearly genetically differentiated, and they are considered to each represent a discrete species. Then, we plotted the collection sites of reliably identified specimens of E. latifolium and E. l-nigrus on the Shinano-gawa River basin map. This resultant map clearly displays that E. latifolium is distributed in the upper stream area rather than E. l-nigrus. To conclude, a pronounced 'habitat segregation' or 'current distribution' is clearly observable. | |||||||||||
