中文摘要	有学者根据植物组成等特性将Yungas雨林定性为独立的生物地理单元,但这些特性主要是定性的且未包括其动物区系组成.Yungas雨林被认为是动植物种类分布丰富的多样性的区域.然而,尚未有研究评估其动物分布记述的状况.在生物地理学上Yungas雨林使人充满兴趣,它函盖不连续分布的雨林且延伸至温带干旱和半干旱地带.该研究分析了Yungas最南端地区小型哺乳动物特有种分布记录,对比了飞行物种(蝙蝠类)和非飞行物种(有袋类)的分布.结果显示小型哺乳动物特有种是Yungas地区的有效指标;所分析的80%小型有袋类物种和55%蝙蝠类物种支持所鉴定的区域作为特有种区域.所研究的区域与阿根廷西北部及其以下的Yungas的植物学定义一致.该区域以前尚未正式用定量方法评测.结果还发现非飞行特有种较之飞行特有种更合适作为区域尺度上的特有种指标,作者认为飞行特物种作为特有种指标比以前所认为的要更好
英文摘要	Several studies have characterized the Yungas as a separate biogeographic unit, mainly based in floristic components. However, these characterizations were mainly qualitative and did not include faunal groups. The Yungas have been assumed as a region with rich floral and faunal diversity, but without testing how well they are described by animal distributions. Our study consists of a formal analysis of endemism based on distribution of small mammals in the southernmost portion of the Yungas. This area is biogeographically very interesting because the Yungas are comprised of discontinuous fragments of forests that extend into temperate arid and semiarid habitats. As a first approximation, we contrasted a group of volant species (bats) versus a group of non-volant species (marsupials). Our results show that small mammals are efficient indicators of endemism in Yungas. Eighty percent of the species of small marsupials included in the analysis supported the identified areas as being zones of endemism. Regarding bats, almost 55 percent of the species supported a designation of endemism. The results also show that the areas we considered are congruent with the botanical definition of the Yungas of northwestern Argentina and their subdivisions, an assumption that had not been previously tested with a formal quantitative method. We also found that non-volant species are better indicators of endemism than volant ones at regional scales, but volant species are better indicators than was previously thought
