Modelling the distribution and interaction of introduced rodents on New Zealand offshore islands
ABSTRACT Aim To establish the factors that correlate with the distribution of the four most commonly introduced rodent species on New Zealand offshore islands — ship rat ( Rattus rattus ), Norway rat ( R. norvegicus ), Pacific rat or kiore ( R. exulans ) and house mouse ( Mus musculus ) — and examin...
