Resumen:
Abstract: The aim of this work was to study the reproductive output and imposex parameters of the caenogastropodBuccinanops globulosusinhabiting a harbour area, with high maritime traffic and pollution. The resultsshowed higher imposex incidence for non-gravid females than for gravid females (carrying egg capsules). Amongimposex-affected females, mean penis size was significantly larger in non-gravid (3.4 mm) than gravid (1.5 mm)females. In B. globulosus usually a single juvenile hatches per egg capsule, but in this study capsules with multipleembryos were found. Overall, these results suggest a relationship between imposex development and alterations onthe reproductive output of B. globulosus females living in adverse environmental conditions (polluted area).
