Non-volant small mammals, which include small-bodied representatives from several mammal orders, have been used as a model group to test the effects of habitat conversion and edge creation on biodiversity. Small mammals occupy a large variety of habitat types and vegetation strata, and have varied lifestyles and diets. They include species with slow-to fast-life history (the Etruscan shrew and European Hare , respectively) and with very specialized to very generalist habits and diets (the Atlantic bamboo rat and house mouse , respectively). There are no databases with global coverage focusing on small mammal composition in natural and human-modified habitats and that include neglected natural habitats (e.g. grasslands and savannas). Here, peer-reviewed articles were searched in the primary literature to synthesize almost half century (1973-2017) of research on small mammal composition in natural forests, grasslands and their natural edges, and in five types of human-modified habitats (human-induced forest edges, human-induced grassland edges, crop fields, clear-cuts and tree plantations). The complete database includes information from 199 peer-reviewed articles. Presence data were obtained for 534 species (including 30 unidentified) in 551 sites distributed in 45 countries, 92 ecoregions, 10 biomes and six realms. Measurements of sampling effort and number of species records (number of individuals, captures) per habitat were also obtained, from which researchers can calculate a measure of abundance standardized by the sampling effort. The database will be useful for researchers interested in local-to broad-scale patterns of alpha- and beta-diversity in natural and human-modified habitats.
非飞行类小型哺乳动物，包括来自几个哺乳纲的小型代表物种，已被用作一个模型组来测试栖息地转换和边缘形成对生物多样性的影响。小型哺乳动物占据了各种各样的栖息地类型和植被层次，并且具有多样的生活方式和饮食。它们包括具有从慢到快生活史的物种（分别为伊特鲁里亚鼩鼱和欧洲野兔）以及具有从非常特化到非常泛化习性和饮食的物种（分别为大西洋竹鼠和家鼠）。目前没有全球范围的数据库专注于自然和人类改造栖息地中的小型哺乳动物组成，并且这些数据库涵盖被忽视的自然栖息地（如草原和稀树草原）。在这里，我们在原始文献中搜索了经过同行评审的文章，以综合近半个世纪（1973 - 2017年）关于自然森林、草原及其自然边缘以及五种人类改造栖息地（人为诱导的森林边缘、人为诱导的草原边缘、农田、皆伐地和人工林）中小型哺乳动物组成的研究。完整的数据库包含来自199篇经过同行评审文章的信息。在分布于45个国家、92个生态区、10个生物群落和六个生物地理界的551个地点获得了534个物种（包括30个未鉴定物种）的存在数据。还获得了每个栖息地的采样工作量测量值和物种记录数量（个体数量、捕获量），研究人员可以据此计算出一个由采样工作量标准化的丰度测量值。该数据库将对那些对自然和人类改造栖息地中从局部到广泛尺度的α和β多样性模式感兴趣的研究人员有用。
