摘要

一个物种的地理范围常常受到抽样方法的限制，低估了其实际分布。这很可能是穴居动物(Microbiotheria)的情况，它是南美洲南部特有的有袋动物。我们使用相机陷阱首次在chait和Futaleufú(智利南部)记录了D. gliroides，将其已知分布向南扩展了100公里。该地区的气候和森林组成不同于典型的瓦尔迪维亚雨林。活动评估显示，与北方人口相比，活动模式狭窄。

Southernmost records of Dromiciops gliroides: extending its distribution beyond the Valdivian rainforest

The geographic range of a species is often limited by sampling approaches, underestimating the actual distribution. This is likely the case of Dromiciops gliroides (Microbiotheria), an endemic marsupial from southern South America. We used camera-traps to record D. gliroides for the first time in Chaitén and Futaleufú (southern Chile), expanding its known distribution 100 km to the south. Climate and forest composition in this area differs from the typical Valdivian rainforest. Activity assessments show a narrow activity patterns compared to northern populations.
