The feeding strategies of two freshwater gastropods, Ancylus fluviatilis
Miill, and Planorbis contortus Linn.
concentricus within Basural Beach with that of populations from other Ancylidae genera elsewhere such as Ancylus fluviatilis Muller, 1774 from Europe, as reported by Geldiay (1956), Durrant (1980), and McMahon (2004) revealed that despite the differences in the latitudes of their habitats, the size frequencies of these species are determined by the ambient water temperature, and their growth rate is the same as one generation per year.
Studies on local populations of the freshwater limpet Ancylus fluviatilis Muller.
The water level rise resulted in widespread erosional processes and accumulation of beach formations, which consisted of shingle, calcareous gravel and sand containing mollusc shells of Ancylus fluviatilis
, Bithynia tentaculata, Radix ovata, etc.
This has already been observed in the highly selfing pulmonate Ancylus fluviatilis (Stadler et al.
