A naturalized species has two ranges. The first range is the one where the species lives in its native habitat. The second range is the one where the species is naturalized, surviving in a nonnative area without the help of humans. Species are more able to survive east to west across the globe, but are limited by latitude. The scientists in this study wanted to answer this question: Are naturalized species’ latitudinal ranges the same, larger, or smaller than their native ranges?
