Abstract: | The effects of Copper on the life-cycle of two crustacean isopods, Asellus aquaticus (L.) and Proasellus coxalis Dollf., are studied. ST50 indicates that females and males are differently sensitive in comparison with juveniles. The two species do not show differences in sensitivity in the range of 0.01–15 mg·1-1 between adults and juveniles. The effect of 0.005 mg·1-1 Copper sulphate was strongest on embryonic and larval stages. Ecological implications are discussed. |
