Effects of Copper and the Insecticide Cypermethrin on a Soil Ciliate (Protozoa: Ciliophora) Community.

Ciliated protozoa play important ecological roles in soils, yet few studies have investigated the effect of soil pollution on them. We determined the effect of copper (Cu) and cypermethrin on a soil ciliate community under microcosm conditions. Soils were treated with Cu or cypermethrin and the abundance and species richness of ciliates determined 15 days later.
