Ecology and impacts of introduced rodents (Rattus spp. and Mus musculus) in the Hawaiian Islands
Introduced rats (Rattus rattus, R. norvegicus, and R. exulans) and/or mice (Mus musculus) occur on more than 80% of the world's island groups, where they pose great threats to native species. Understanding the interactions between these introduced rodents and the environments which they have …
