Abstract
Larval statoliths of the temperate neogastropod Concholepas concholepas (Bruguiere, 1789) appear to have great utility for reconstructing larval dispersal history. Hatch- ing marks on the statoliths seem to demarcate the natal core of recent recruits. Analysis of individual larval statoliths by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) indicates detectable levels of multiple trace ele- ments. Differences in Ba/Ca, Zn/Ca, and Pb/Ca in the larval core of C. concholepas statoliths from 3 geographically sepa- rated sites in Chile suggest these mineralized hard parts could function as natural tags of natal origin and hence be useful in ecological studies of larval dispersal pathways.
