  abstract = {{T}o understand patterns of genetic and morphological variability, population structure and dispersal dynamics of the invasive bivalve {P}inctada imbricata radiata ({L}each, 1814) in {T}unisian waters, we studied 200 individuals from five different sites (natural, polluted and/or subjected to environmental and anthropogenic pressures) using 10 enzymatic systems and six shell measurements. {I}n this study, we attempt to elucidate the relationship between the spreading ability and the adaptive potential of the species under various environmental stresses. {F}ourteen putative enzyme-coding loci were resolved, six of which were polymorphic at the level of 99%. {P}. imbricata radiata maintains a relatively consistent level of polymorphism at the genetic markers studied, since 10% of individuals were heterozygous. {T}he mean {F}-{IS} value was positive and significant in two samples. {H}owever, the remaining samples collected from the disturbed marine sites (polluted, urban and lagoon areas) were at {H}ardy-{W}einberg equilibrium. {H}ighly significant genetic (mean {F}-{ST}=0.022, {P}<0.001) and morphological ({W}ilks' lambda=0.0814, approximate {F}-20,{F}- 627=35.484, {P}<0.001) differentiations between samples were observed, with no evidence of isolation caused by geographic distance. {H}owever, the {M}antel test performed between genetic and morphological distances revealed a significant correlation. {O}ur results indicate that natural selection seems to have a greater influence on genetic differentiation in {P}. imbricata radiata than genetic drift. {T}he combination of genetic and morphological data provided important theoretical information for determining the invasion mechanisms of the species.},
