  abstract = {{T}he detrimental effects of the introduced ship rat on bird species on the {L}avezzi {M}editerranean archipelago has led to the decision to eradicate the rodent from the main island, {L}avezzu (73 ha), as well as from several neighbouring islets. {A} genetic study using eight microsatellite markers has revealed some of the dynamics of this rat population. {F}irst, it has been shown that the rat population was genetically stable (no departure from {H}ardy-{W}einberg equilibrium and no linkage disequilibrium) and as suggested by paleontological data, established for a long time. {T}his information is encouraging in term of viability of the eradication campaign in the long term, even if rare immigration events cannot be excluded. {S}econd, this study shows that rats are likely to swim between the main island and the islets quite regularly since no clear genetic differentiation has been detected between them. {T}his result is quite surprising since the ship rat is not known for its swimming abilities. {T}hird, a cryptic genetic structure has been detected on the main island, with the north peninsula differentiated from the rest. {T}his result correlates the observation of particular predation behaviours only observed in this part of the island. {F}inally, evolutionary hypotheses (e.g., dispersal limitation, emergence of family groups, local adaptation) are discussed to explain the genetic patterns observed and the population functioning inferred. {T}hese results should be of particular interest to wildlife managers concerned with rat eradications, and also provide clear insights into the study of other biological invasions.},
