It is difficult to predict the outcome of the removal of key species, such as a top predator, given the numerous and complex population interactions among island species, and justifies careful pre‐control study and preparation prior to initiating the eradication of an alien species, in order to avoid an ecological catastrophe.

To be successful, large-scale rodent campaigns should be integrated with programs to improve the livelihoods of residents, island biosecurity, and reinvasion response programs, and applied research can further aid in minimizing impacts.
Importance of Assessing Population Genetic Structure before Eradication of Invasive Species: Examples from Insular Norway Rat Populations
Abstract: Determining the inter‐island migration abilities of pest species and delimiting eradication units enable more viable long‐term eradication campaigns because recurrent colonization from…
Phylogeography of the introduced species Rattus rattus in the western Indian Ocean, with special emphasis on the colonization history of Madagascar
The phylogeographic patterns of the black rat from islands in the western Indian Ocean where the species has been introduced are described in comparison with the postulated source area (India).
Divergent evolutionary processes associated with colonization of offshore islands
The results suggest that a recent and widespread cytb replacement event in the continental source area purged cytb variation there, whereas the ancestral diversity is largely retained in the colonized islands as a genetic ‘ark’.

To achieve long‐term eradication on these islets, it seems necessary to redevelop the eradication procedure to avoid individuals surviving and to prevent reinvasion, probably from the mainland, by installing permanent trapping and poisoning devices and conducting regular monitoring.
Island colonization and founder effects: the invasion of the Guadeloupe islands by ship rats (Rattus rattus)
The results indicate that rats were introduced on Guadeloupe first, which then became the source population for independent secondary colonization of Fajou and Petite‐Terre, and could be interpreted as the remaining signature of the early introduction of the ship rat in the archipelago.
French attempts to eradicate non-indigenous mammals and their consequences for native biota
Many European politicians, managers, and scientists believe that non-indigenous species cannot be eradicated and that attempts to do so are hazardous because of frequent undesirable results. This…
Inventory of wild rodents and lagomorphs as natural hosts of Fasciola hepatica on a farm located in a humid area in Loire Atlantique (France).
The results indicate that M. coypus may play a role in the maintenance and the dissemination of F. hepatica in various environments and open a discussion on the role of other natural wild hosts.
