Abstract

Madagascar, as one of the global biodiversity hotspots, hosts numerous unique terrestrial mammal species that need urgent protection. To identify priority species for conservation, an updated list of terrestrial Malagasy mammal species was compiled, including their threat status, distribution, endemism level, Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) listing, and Evolutionarily Distinct and Globally Endangered (EDGE) score. An overview of these species kept in zoos worldwide was created using the Zoological Information Management System and Zootierliste to assess ex situ conservation efforts. Nearly 60% of the 212 native terrestrial mammal species are threatened with extinction, with 18% being regional endemics, 39% microendemics, and 42% endemics. The majority of these species (92%) occur within protected areas. About half of Madagascar’s mammals are listed under CITES, and less than half have an EDGE score. Only 34 species are kept in zoos globally, with 26 Red-Listed as threatened. Nine out of seventeen families are not represented in zoos. A total of 1545 institutions, primarily in Europe and North America, keep Malagasy mammal species, with successful reproduction reported for 28 species in the last 12 months, 23 of them listed as threatened on the IUCN Red List. To maximize conservation, we recommend reallocating resources towards priority species and implementing concerted ex situ and in situ actions as proposed by the IUCN’s One Plan Approach.
根据世界自然保护联盟的 "一个保护计划方法 "优先考虑马达加斯加哺乳动物物种的原生境保护
马达加斯加是全球生物多样性热点地区之一,拥有众多亟需保护的独特陆生哺乳动物物种。为了确定需要优先保护的物种,我们编制了一份最新的马达加斯加陆生哺乳动物物种清单,其中包括这些物种的威胁状况、分布情况、特有程度、《濒危野生动植物种国际贸易公约》(CITES)列名情况以及进化独特性和全球濒危程度(EDGE)评分。我们利用动物信息管理系统(Zoological Information Management System)和动物名录(Zootierliste)对全球动物园中饲养的这些物种进行了概述,以评估异地保护工作。在212种本土陆生哺乳动物中,近60%濒临灭绝,其中18%为地区特有物种,39%为微型特有物种,42%为地方特有物种。这些物种中的大多数(92%)都分布在保护区内。马达加斯加约有一半的哺乳动物被列入《濒危野生动植物种国际贸易公约》(CITES),只有不到一半的哺乳动物获得了 "EDGE "评分。全球仅有 34 个物种在动物园饲养,其中 26 个物种被红色名录列为濒危物种。十七个科中有九个科在动物园中没有代表。共有 1545 家机构(主要在欧洲和北美)饲养马达加斯加哺乳动物,在过去 12 个月中,有 28 个物种成功繁殖,其中 23 个物种在世界自然保护联盟红色名录中被列为濒危物种。为了最大限度地保护这些物种,我们建议将资源重新分配给优先物种,并按照世界自然保护联盟的 "一个计划方法"(One Plan Approach)建议,在原地和非原地采取协调一致的行动。
