<p>The objective of the present study was to elucidate the distribution characteristic of Neripteron pileolus (Neritidae, Gastropoda), one of the endangered species in Japan, at two tidal flats around the river mouth in Tokushima Prefecture, Shikoku Island. We investigated the distribution of gastropods including Neripteron pileolus and several environmental variables at (1) 70 (small scale) and 124 stations (large scale) at a reed marsh in the Yoshino River Estuary in October 2004 and 2007; and (2) 130 stations at the Katsuura River Estuary in October 2005. Assimineidae spp., Neripteron pileolus, and Cerithidea moerchii were the dominant species in the reed marsh at the Yoshino River. The population density of Neripteron pileolus in the Yoshino River was higher than that in the Katsuura River. Further, the reed density was almost similar between the Yoshino and Katsuura Rivers. However, the number of dead leaves of reed in the Yoshino River was 14 times higher than that in the Katsuura River. The small-sized Neripteron pileolus (< 11 mm) were found to be attached to the dead leaves of reed. The multi-regression analysis and decision tree at different time and space revealed that the number of dead leaves of reed is the most important environmental variable affecting the distribution of Neripteron pileolus</p>
