Five bitterling species were found in 11 sites in the system. Although Rhodeus ocellatus kurumeus was found to be distributed in 23 sites in 1983, this species was found in three sites in this study. The population of the bitterlings decreased in the sites with a high urbanization rate, although the populations of several other fish species showed no dependence on the urbanization rate. The population of the mussels showed a negative correlation with urbanization rate. In addition, the mussels populations showed positive relationship with the bitterling populations. These three relationships indicate that the decrease in the bitterling population due to the urbanization of the watershed was responsible for the decrease in the mussel population., 近縁外来種の侵入が在来種に与える生態・遺伝的影響に関する実証的研究}, pages = {837--842}, title = {多々良川水系におけるタナゴ類の分布域の推移とタナゴ類・二枚貝の生息に及ぼす都市化の影響}, volume = {29}, year = {2010} }
