Variation in cadmium uptake, feeding rate, and life-history effects in the gastropod potamopyrgus antipodarum: linking toxicant effects on individuals to the population level.

Abstract excerpt

A life-table response experiment was performed to investigate the effects of sediment-bound cadmium on individual life-history traits and feeding rates of four clones of Potamopyrgus antipodarum. Demographic effects were evaluated using a simple two-stage model to estimate population growth rate (lambda). Decomposition analysis was performed to investigate the contributions of each of the affected life-history...
