Here, we conducted a survey to examine the diversity, distribution and habitat association of small mammals from August 2011 to February 2012 incorporating both wet and dry seasons in Aridtsy forest, Awi Zone, Ethiopia. Using Sherman live traps and snap traps in four randomly selected trapping grids, namely, natural forest, bushland, grassland and farmland, a total of 468 individuals comprising eight species of small mammals (live traps) and 89 rodents of six species (snap traps) were trapped in 2352 and 1200 trap nights, respectively. The trapped small mammals included seven rodents and one insectivore: Lophuromys flavopuntatus (30.6%), Arvicanthis dembeensis (25.8%), Stenocephalemys albipes (20%), Mastomys natalensis (11.6%), Pelomys harringtoni (6.4%), Acomys cahirinus (4.3%), Lemniscomys zebra (0.2%) and the greater red musk shrew (Crocidura flavescens, 1.1%). Analysis showed statistically significant variations in the abundance and habitat preferences of small mammals between habitats during wet and dry seasons.
2011年8月至2012年2月期间，我们在埃塞俄比亚阿维地区干旱森林进行了一项调查，以研究小型哺乳动物的多样性、分布及其与栖息地的关系，该时间段涵盖了雨季和旱季。在四个随机选取的诱捕网格（即天然森林、灌木丛、草地和农田）中使用谢尔曼活捕陷阱和弹簧夹陷阱，分别在2352个和1200个诱捕夜中，共捕获了468只个体，其中包括8种小型哺乳动物（活捕陷阱捕获）和6种89只啮齿动物（弹簧夹陷阱捕获）。捕获的小型哺乳动物包括7种啮齿动物和1种食虫动物：黄腹非洲攀鼠（30.6%）、邓氏草鼠（25.8%）、白足狭颅鼠（白足鼠，20%）、南非小家鼠（11.6%）、哈氏柔毛鼠（6.4%）、埃及刺鼠（4.3%）、条纹林鼠（0.2%）和大赤麝鼩（黄麝鼩，1.1%）。分析表明，在雨季和旱季，不同栖息地小型哺乳动物的丰度和栖息地偏好存在统计学上的显著差异。
