Abstract

Abstract The recently established Chebera Churchura National Park represents a mosaic of savanna and montane evergreen forest. A report on small mammals (2013) showed their relatively high diversity, but species identification was based only on external morphology. We conducted a new field survey and genetic analyses to shed light on diversity and biogeographical affinities of small mammals in this under-explored national park. Based on results of mitochondrial DNA barcoding, 14 species of rodents and two species of shrews, including Crocidura turba (new to the Ethiopian fauna), were identified. Moreover, a new taxon of gerbils – presumably representing a new species – of the genus Gerbilliscus was discovered. We show that forest and savanna species often inhabit the same localities, which can be explained by the mosaic nature of biotopes. These results document the uniqueness of Chebera Churchura NP, especially in comparison with other Ethiopian national parks, and argue for its protection and further development.

在埃塞俄比亚的Chebera Churchura国家公园发现啮齿动物和鼩鼱的多样性

最近成立的Chebera Churchura国家公园代表了稀树草原和山地常绿森林的马赛克。一份关于小型哺乳动物的报告(2013)显示了它们相对较高的多样性，但物种鉴定仅基于外部形态。我们进行了一项新的实地调查和遗传分析，以揭示这个未被开发的国家公园中小型哺乳动物的多样性和生物地理亲和性。根据线粒体DNA条形码的结果，鉴定出14种啮齿类动物和2种鼩鼱，包括Crocidura turba(埃塞俄比亚动物群的新物种)。此外，还发现了沙鼠属的一个新分类群——可能代表了一个新物种。我们发现森林和稀树草原物种经常栖息在相同的地方，这可以用生物群落的马赛克性质来解释。这些结果证明了Chebera Churchura国家公园的独特性，特别是与其他埃塞俄比亚国家公园相比，并主张对其进行保护和进一步开发。

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
