Comparative influence of genetics, ontogeny and the environment on elemental fingerprints in the shell of Perna canaliculus

Abstract The trace elemental composition of biogenic calcium carbonate (CaCO3) structures is thought to reflect environmental conditions at their time of formation. As CaCO3 structures such as shell are deposited incrementally, sequential analysis of these structures allows reconstructions of animal...
