摘要(Abstract):
2004年10~12月对青岛太平角潮间带2种海藻(鼠尾藻和羊栖菜)上附生的小型底栖动物进行了连续3个月的采样调查,并进行了附植小型底栖动物优势类群和线虫优势种类ATP含量的测定。2种海藻上共采得12个小型底栖动物类群,平均丰度为518.9nds./g dwt algae,海洋线虫和桡足类为优势类群,两者的相对丰度之和大于84%。鼠尾藻上的线虫ATP含量平均为5.57ng/ind.(以下单位相同),桡足类为4.69;羊栖菜上的线虫ATP含量平均为2.46,桡足类为15.06。共鉴定出海洋线虫28种或分类实体。2种海藻上的线虫优势种类均是刮食食性的三齿棘线虫(Acanthonchus tridentatus)。不同粒级海洋线虫的个体干重为0.14~32.65μg/ind.,ATP含量为1.18~297.64ng/ind.,C/ATP比值为43∶1~99∶1。
