A method is described for assessing the effects of metals on the food consumption rate of isopods from measurements of fecal production. The effects of zinc in the diets of two isopod species, Porcellio scaber and Oniscus asellus, were tested. The metal was fed to the isopods on leaves of field maple (Acer campestre) contaminated with concentrations ranging between 1000 and 10,000 micrograms Zn g-1 leaf dry wt. Significant reductions in feeding rates were observed of the highest concentrations of zinc. The test employed in this study is quick, cheap, and relevant for estimating sublethal effects of metals on isopods.
本文描述了一种通过测量粪便产量来评估金属对等足类动物食物消耗率影响的方法。测试了锌对两种等足类动物（粗糙真地鳖和普通鼠妇）饮食的影响。将金属添加到被锌污染的挪威枫树叶（锌浓度在1000至10000微克锌/克叶片干重之间）上，然后喂食给等足类动物。在锌浓度最高时，观察到摄食率显著降低。本研究中采用的测试方法快速、廉价，且对于估计金属对等足类动物的亚致死效应具有相关性。
