通过17个月的野外调查和实验室实验，研究了日本中部多摩河口泥滩中与大虾Upogebia major和大眼蟹Macrophthalmus nervus洞穴相关的Poecilostomatoid桡足类Hemicyclops gomsoensis的生活史、季节性种群波动和耐盐性。根据对水柱和洞穴中的样品采集结果表明，H。gomsoensis在无节幼体阶段是浮游的，在第一个桡足类阶段定居在底部，居住在U.主要的，在较小的程度上，M。- 是的在全年都有携带卵囊的雌性的情况下，桡足类的繁殖主要发生在初夏至秋季，秋季至冬季繁殖量逐渐减少。有时，洞穴中的桡足类种群会遭受河水的严重冲刷，导致洞穴水的盐度下降到致命的水平，但通常洞穴中的盐度在最佳水平内，并允许种群的恢复和维持。
A 17-month field survey and laboratory experiments were conducted to investigate the life cycle, seasonal population fluctuations, and salinity tolerance in the poecilostomatoid copepod Hemicyclops gomsoensis associated with the burrows of the mud shrimp Upogebia major and the ocypodid crab Macrophthalmus japonicus in the mud-flats of the Tama-River estuary, central Japan. On the basis of sample collections in the water column and from the burrows, it was revealed that H. gomsoensis is planktonic during the naupliar stages and settles on the bottom during the first copepodid stage to inhabit the burrows of U. major and, to a lesser extent, those of M. japonicus. While females carry- ing egg-sacs were present throughout the year, the copepods' reproduction took place mainly during early summer to autumn with a successive decrease from autumn to winter. Occasionally the copepod populations in the burrows suf- fered from severe flushes of river water that led to salinity decreases in the burrow water to fatal levels, but usually the salinity in the burrow was within optimal levels and permitted recovery and maintenance of the populations.
