比较了日本中部下田欧拉湾和日本北部函馆相距较远的两个种群潮间带寄居蟹的贝壳利用模式，以及同域寄居蟹的贝壳资源利用率和贝壳利用格局。欧拉湾和函馆海湾主要利用贝壳的腹足类种类不同，贝壳利用模式与贝壳的可获得性不一致。中华绒螯蟹与其他同域寄居蟹在贝壳利用上存在明显差异，其贝壳生态位重叠指数和栖息地利用指数在函馆湾高于欧拉湾。相较于欧拉湾，函馆湾丰富的贝壳资源供应被认为是导致两地生态位重叠程度差异的一个因素。
Shell utilization patterns of the intertidal hermit crab Pagurus filholi were compared between two distant local populations from Oura Bay, Shimoda, central Japan, and Hakodate Bay, Hakodate, northern Japan, in conjunction with the shell resource availability and shell utilization patterns of sympatric hermit crabs. Gastropod species of shells dominantly utilized by P. filholi differed between Oura Bay and Hakodate Bay, and shell utilization patterns did not correspond to the availability of shells in both study localities. Between P. filholi and other sympatric hermit crabs, there were some clear differences in shell species utilized in both localities, and values of niche overlap indices in shell and habitat utilizations between P. filholi and other crabs were higher in Hakodate Bay than in Oura Bay. The rich supply of shell resources in Hakodate Bay compared to Oura Bay is considered to be a factor responsible for the difference in the degree of niche overlapping between the two localities.
