dc.description.abstractIn marine species, oceanographic discontinuities may be permanent and asymmetric, allowing mostly unidirectional gene flow. Nonetheless, even so-called permanent fronts can fluctuate, allowing for changes in migrant direction. We analyzed spatial genetic differentiation in the crab Liocarcinus depurator across the three main oceanographic discontinuities found along the western Mediterranean: Gibraltar Strait, Almeria-Oran Front and Ibiza Channel. A partial fragment of the cytochrome oxidase I gene was sequenced in more than 400 individuals collected in five localities during four different time periods, so that genetic changes could be estimated across space and time. The intensity of interannual differences varied among populations, probably due to local shifts in circulation patterns modifying the asymmetric flow. The discrepancies previously reported on the effect of oceanographic discontinuities over multiple species could result from time-space interactions on the distribution of genetic variation. The present study highlights the importance of temporal replicates to better understand the spatial genetic structure of marine species and implement better management strategies for their conservation-
