【 摘 要 】

In this study some ecological studies were carried out on the local populations of Ancylus fluviatilis Müller 1774, from March 1995 to March 1996. Temperature of water, pH, conductivity, oxygen values, structure of ground, faunal and floral features of each localities' were investigated monthly, and as well as the effects of these ecological factors on the distribution of this species, the population density, structure and growth. Also same ecological surveys were realised on the 3 freshwater stations where this species is absent and compared with the other localities.
