| Research Abstract |
）：Density of Haustorioides japonicus in summer shows a spatial variation. Recruitment of juveniles caused this variation, but the other life history characteristics did not affect it. Location of sandy shores including slope of offshore seafloor could explain this variation, while analyses on food web structure and genetic composition could not. So, these results suggested that the spatial variation in production of H. japonicus was due to the effect of shore environment on its early life stage.
