Document Summary
Dispersal the transport of organisms from place of reproducion to habitat. Gypsy moth naive to eurasia, the larvae does most of the feeding. It was inadvertently introduced to north america just outside boston. Got out started to reproduce and spread in massachusets and went everywhere and started populaion in michigan. They are prone to outbreaks that defoliate trees like large parts of forest. Can be thought of inadvertent unfortunated transplant experiment. In eurasia there are natural enemies and they didn"t in north america. Limited dispersal abiliies- the north atlanic was a barrier to dispersal and needed to be moved over. Zebra mussels released into great lakes from european ships same type of thing. Naive to chain of islands in alaska and down through shore to southern california. All these waters are cold and they have insulated fur so huning ended up making them almost exinct for fur.
