Interannual fuctuations in connectivity among crab populations (Liocarcinus depurator) along theAtlantic‑Mediterranean transition
An interesting evolutionary question that still remains open is the connectivity between marine populations. Marine currents can favour the dispersal of larvae or adults, but they can also produce eddies and gyres generating oceanographic fronts, thus limiting gene flow. To address this subject, we...

An interesting evolutionary question that still remains open is the connectivity between marine populations.
