Abstract

The Fingui white-toothed shrew Crocidura fingui, categorized as Data Deficient on the IUCN Red List, is endemic to Príncipe Island, Central Africa. It is currently known from < 10 sites and its ecology and any threats are largely unknown. We review its distribution and ecology, and any potential threats, based on camera-trap data, field observations and previously published and unpublished sightings. Crocidura fingui appears to have an island-wide distribution and to use a range of ecosystems, from native forests to urban areas. It is largely nocturnal and exhibits considerable spatiotemporal overlap with introduced mammals such as the African civet Civettictis civetta, domestic cat Felis catus and rats Rattus spp. The species has an area of occupancy < 500 km2 and is known from fewer than five locations, and its population is inferred to be affected by several introduced mammals. We recommend that it is recategorized as Endangered on the IUCN Red List.

重新评估几内亚湾普林西比岛特有的鼩鼱（Crocidura fingui）的保护状况

芬吉白齿鼩（Crocidura fingui）在《世界自然保护联盟红色名录》中被列为数据不足物种，是中非普林西比岛的特有物种。目前，人们只知道它分布于 10 个地点，其生态环境和面临的威胁在很大程度上还不为人所知。我们根据相机诱捕数据、野外观察结果以及以前发表和未发表的目击报告，回顾了它的分布和生态情况，以及任何潜在的威胁。Crocidura fingui似乎分布于全岛，生活在从原始森林到城市地区的一系列生态系统中。它主要在夜间活动，与非洲果子狸、家猫和大鼠等引进的哺乳动物在时空上有相当大的重叠。该物种的活动区域为 500 平方公里，已知的分布地点不到 5 个，其种群推断受到几种引进哺乳动物的影响。我们建议在《世界自然保护联盟红色名录》中将其重新归类为濒危物种。
