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Ca^(2+)时,沙蚕的体积调节能力必然丧失。
The volume regulation of the salt, Ca^(2+)and Mg^(2+)in Perinereis aibuhitensis Grube has been studied, and found that it is a good osmoregulator at low salinities (from 107mmolCl·dm^(-3)to 534mmolcl·dm^(-3)) however, these animals lose their ability to control their volume in the absence of external calcium ions.
