Coastal lagoons are habitats exposed to wide environ-
mental variations, particularly as regards salinity and
temperature, which may cause strong selective pressures
on organisms. These characteristics suggest that environ-
mental factors directly modify the genetic patterns of spe-
cies (GonzaŽlez-Wangušemert et al. 2006, 2009) and could
contribute to the genetic divergence among populations,
associated with physical and ecological discontinuities
between coastal lagoon and open-coast environments
(Bilton et al. 2002; Iannotta et al. 2008).
The sand goby Pomatoschistus marmoratus (Risso,
1810), a small fish found inshore over sandy bottoms, is
