【摘要】 经对双齿围沙蚕在不同环境条件下的体积调节能力研究,发现在盐度为107mmolCl·dm^-3以上的海水中,其调节能力较强,否则其调节能力显著下降。当环境中缺乏Ca²⁺时,沙蚕的体积调节能力必然丧失。更多还原

【Abstract】 The volume regulation of the salt, Ca²⁺and Mg²⁺in Perinereis aibuhitensis Grube has been studied, and found that it is a good osmoregulator at low salinities (from 107mmolCl·dm^-3to 534mmolcl·dm^-3) however, these animals lose their ability to control their volume in the absence of external calcium ions.更多还原
