对北海道东北部阿克西地区两种同域寄居蟹的分布、繁殖生物学和贝壳利用模式进行了研究。中登氏寄居蟹和臂胸寄居蟹的空间分布高度重叠，个体大小相似，但它们对贝壳的利用和繁殖季节存在明显差异。由于种间差异的壳利用模式同意与实验确定的壳的偏好差异，我们得出结论，种间差异的壳偏好的结果在现场观察到的壳利用模式。种间差异的生殖期，壳利用模式和壳的偏好的结论是因素，允许共存的两个Pagurus种在Akkeshi。这项研究是一个共存的寄居蟹资源分割的例子。
The distribution, reproductive biology and shell utilization pattern of two sympatric hermit crab species in Akkeshi, north-eastern Hokkaido, were examined. Although spatial distributions of Pagurus middendorffii and P. brachiomastus highly overlapped and their body sizes were similar, their shell utilization and breeding season markedly differed. Since interspecific differences in the shell utilization pattern agreed with the experimentally determined shell preference difference, we conclude that the interspecific difference in shell preference results in the shell utilization patterns observed in the field. The interspecific difference in the reproductive period, shell utilization pattern and shell preference are concluded to be factors that allow the coexistence of the two Pagurus species in Akkeshi. This study is an example of resource partitioning by coexisting hermit crabs.
