Abstract
A model to predict the distribution of Ocypodidae at estuaries was developed based on quantification theory type 2. Using salinity, altitude of habitat, silt contents in sediments, AVS contents and hardness of sediments as habitat indices, which were obtained in tidal area of the Yoshino River in Shikoku, Japan, the distribution of three species in Ocypodidae could be predicted with accuracy of 72%. The model is useful for predicting the faunal change of Ocypodidae due to an environmental modification and for predicting the establishment of its community after a creation of habitat as restoration work.
