Due to the change of the fundamental and realized niche, an invasive alien species (IAS) often shifts niches after it has established successfully and spread widely at the invaded region. Usually the direct evidence of the niche shift is difficult to achieve. The ecological niche models (ENMs) can be employed to predict the potential distribution of an invasive species in the invaded area based on the niche requirement of the species in its origin areas, given that its niche conserved when invaded in another region. Some indirect evidences of niche shift during biological invasion were found b...
