Mode d'Introduction: Notes sur l'espèce pour cette localité:
The Norway rat was brought into Xinjiang Autonomous Region from central China as a hitchhiker through the railways. The first Norway rat was caught in Xinjiang in 1975, and wild populations are now well established in Turpan prefecture and Urumiqi City in Xinjiang. Norway rat populations are expanding north and south in Xinjiang along railways, as well as to areas of agriculture and animal husbandry along roads. Survey data indicate a stable population structure, with breeding ages becoming a little earlier and body size getting larger. In the croplands of Miquan county, the Norway rat is outcompeting other species of rats and becoming the predominant species (Zhang, et al. 1993 in Xie et al. 2001).
