“…At several sampling sites in the present study, cadmium and zinc concentrations in the water exceeded No Observed Effect Concentrations (NOEL) for growth, reproduction, or mortality during chronic experiments (Postma et al, 1994 ;Timmermans etal., 1992) . In addition, selection experiments performed in the laboratory have shown that cadmium tolerance can increase, when populations are continuously exposed to concentrations in the water, comparable to the field situation (Postma & Davids, 1995) .…”

Key words : Chironomus riparius, metal tolerance, Cd, Zn, Fe Abstract Metal tolerance in Chironomus riparius (Diptera) populations from contaminated streams was studied by comparing the effects of cadmium, zinc and iron on first generation laboratory reared midges . First instar larvae were exposed for four days, after which surviving larvae were counted and their length measured . Larvae from two highly polluted sites, kept under control conditions, grew substantially slower than those from other populations . All populations showed the same growth responses to increased zinc concentrations, but differences were found in the responses to both cadmium and iron . Since population differentiation was demonstrated in first generation laboratory animals, it is suggested that the differences between populations of C . riparius have a genetic basis .

Abstract. The relationships between population growth rate and the life-cycle traits contributing to it are nonlinear and variable. This has made it difficult for ecologists to consistently predict changes in population dynamics from observations on changes in life-cycle traits. We show that traits having a high sensitivity to chemical toxicants tend to have a low elasticity, meaning that changes in them have a relatively low impact on population growth rate, compared to other life-cycle traits. This makes evolutionary sense in that there should be selection against variability in population growth rate. In particular, we found that fecundity was generally more sensitive to chemical stress than was juvenile or adult survival or time to first reproduction, whereas fecundity typically had a lower elasticity than the other life-cycle traits. Similar relationships have been recorded in field populations for a wide range of taxa, but the conclusions were necessarily more tentative because stochastic effects and confounding variables could not be excluded. Better knowledge of these relationships can be used to optimize population management and protection strategies and to increase understanding of the drivers of population dynamics.
