Abstract
The mode of metal accumulation employed by the terrestrial talitrid amphipod Arcitalitrus dorrieni (Hunt) feeding on leaf litter variously enriched with the essential metals copper and zinc have been established in the laboratory. Body concentrations of both metals were found to increase over time correlating with the increasing dietary metal concentrations. Field trials to assess the potential use of this amphipod as a terrestrial biomonitor for ambient copper and zinc availabilities in leaf litter are described. The results indicate a potential biomonitoring capacity for zinc (and possibly for copper also). The presently restricted distribution of this species, however, limits its biomonitoring potential to metalliferous areas of S.W. England, but reflects unknown potential in its native Australia.
