緬甸小鼠（Rattus e xulans Peale）之棲群分佈

"Distribution of the invasive Polynesian rat, Rattus exulans (Peale), in Taiwan."

外來種的入侵經常會影響原生物種的生存及生態系的結構與功能，對一地區的生態產生極大的影響。若入侵外來物種具有較強拓殖能力時，除可能立即在非原生地立足，使當地的動物相漸趨均質化，更可能立即危害農業與公共衛生。

"The Polynesian rat (Rattus e xulans(Peale)), a widely distributed rat in Southeast Asia and Pacific Islands was found in Taiwan in 1999, and was thought to be a new invader of unknown origin. From preliminary survey data, it seems to be distributed in Chian Village, Hualien on the northern bank of the Mugua Stream. A survey was made from January to November 2003 to study the distribution and status of R. e xulans in that area and further to propose an eradication strategy. The survey data indicate that R. e xulans is distributed in the area bordered by Highway 9 on the west, Jian Stream on the north, and Mugua Stream on the south. No R. e xulans was captured in the field on the west side of Highway 9 during this survey."
