Spatio-temporal dynamics of an introduced predator on a sub-antartic island : toward the example of the feral cat (Felis silvestric catus) on the grand Terre Island of the Kerguelen Archipelago

Sub-Antarctic ecosystems are particularly vulnerable to environmental perturbations including biological invasions. The introduction of the feral cat (Felis silvestris catus) on the Grande TerreIsland of the Kerguelen archipelago has lead to detrimental effects on seabird's communities. Cat sur...
