Demographic methods can translate toxicant effects on individuals into consequences for populations. To date few such studies have been conducted with longer-lived invertebrates. This is because full life-cycle experiments are difficult with such species. Here we report the effects of copper and cadmium on the key demographic parameter intrinsic rate of population increase (r) in a long-lived invertebrate (an earthworm). The approach used to derive r was based on robust measurement of effects… CONTINUE READING
