dc.description.abstract | One of the many ways humans alter the environment is through chemicals. For example, copper sulfate is used as a molluscicide to kill certain target species of snails as a method of controlling swimmer't itch. We looked at the effect of copper sulfate, at varying concentrations, on three snail species found in Douglas Lake, Michigan (Campeloma decisum and Elimia livescens, both non-target species, and Physa parkeri, a target species). We expected to find higher mortality at higher concentrations of CuSO4 and higher mortality in P. parkeri than C. decisum and E. livescens. We placed snails in aquaria with varying concentrations of copper sulfate. We found that higher copper sulfate concentrations caused higher snail mortality for all species (X2 = 26.249, d.f. = 1, p < 0.001). We also found that the species C. decisum and E. livescens had lower mortality rates than P. parkeri in CuSO4 concentrations between 1/32-1/70 of the recommended dose (X2 = 17.063, d.f. = 1, p < 0.001). Since the target species survival was lower than that of the non-target species, it suggests that there is a concentration of copper sulfate that would reduce non-target death while remaining effective against target species. | en_US |
