摘要：Islands have been widely recognized as natural laboratories in ecological and evolutionary studies (1, 2). Compared to mainland species, species endemic to islands (i.e., island endemics) may only occupy a small part of their fundamental niche due to dispersal limitation caused by surrounding water (3). When being introduced to new areas, island endemics very likely expand their realized niche as a consequence of the increased availability of suitable environments (3). Understanding such niche changes of island endemics is not only important for predicting their future distribution in areas where they were introduced but also for anticipating the response of other species with limited distributions.
