Abstract

The exuvial loss, subsequent uptake, and tissue and body distributions of the essential trace metals copper and zinc were investigated in an ecological series of talitrid amphipods, immediately after moult and throughout a post-moult period. Negligible quantities of copper or zinc were detected in cast exuvia of individual talitrids. Neither tissue nor whole body copper and zinc concentrations underwent significant changes during the moult cycle and all species showed extreme conservatism in their handling of body copper. There appeared to be no differential treatment of copper between species at the time of moult throughout the ecological series, with no obvious increase in copper retention by the more terrestrial species. The impact of moult cycle stage therefore is unlikely to affect the use of littoral talitrid amphipods as biomonitors for ambient copper and zinc concentrations.
