The study suggests that this loss of naïveté varies among native species, probably as a consequence of the intensity of the threat and of time since introduction, and argues for re-thinking the behavioral flexibility of ectothermic reptiles in terms of their responses to biological invasion.
Knocking on Heaven's Door: Are Novel Invaders Necessarily Facing Naïve Native Species on Islands?
Results indicate that insular species living in contact with invasive alien species for centuries may be, although not systematically, predisposed toward developing adaptive behavior with respect to species belonging to the same archetype and introduced into their native range.
Anti‐predator behaviour in a procellariid seabird: Wedge‐tailed shearwaters do not respond to the odour of introduced ship rats
The wedge-tailed shearwater either did not detect or did not avoid the odour of the ship rat, despite about 175 years of coexistence between rats and shearwaters in New Caledonia, highlighting the need for further investigations into the factors underpinning the paradox between high vulnerability and the surprising long-term coexist between procellariid seabirds and alien invasive rats.
