Abstract

VILCHES, Carlos; PRADENAS, Julio; QUINONES, Adriana  and  BRANTE, Antonio. Association of Crepidula coquimbensis with Pagurus edwardsi: effect on dispersal potential and population genetic structure. Rev. biol. mar. oceanogr. [online]. 2012, vol.47, n.2, pp.327-331. ISSN 0718-1957.  http://dx.doi.org/10.4067/S0718-19572012000200014.

Crepidula coquimbensis is a protandric marine gastropod with direct development and restricted mobility, which only inhabits inside of empty shells of other marine gastropods cohabiting with hermit crabs of the genus Pagurus. In this study, we report potential dispersal mechanisms of C. coquimbensis and the effect on its population genetic distance and structure, using the gene COI, in three localities of northern Chile. The results suggested that C. coquimbensis shows high levels of genetic differentiation at local scale, and the association with P. edwardsi would be its only one mechanism of dispersal.

Keywords : Life history; marine gastropod; protandrism; hermit crab.
