摘要

小熊猫Ailurus fulgens是一种濒危的小型食肉动物,分布在不丹、印度、缅甸、尼泊尔和中华人民共和国。由于栖息地丧失、破碎化、狩猎和偷猎,野生小熊猫的数量在过去三代中减少了50%。1979年,为该物种建立了一个国际研究记录,以监测人类护理中人口统计学上小而不稳定的种群。当时的育种结果很差。1985年,欧洲濒危物种计划(EEP)启动,从那时起,随着育种技术的改进,小熊猫的数量开始增长。截至2019年12月31日,在182个机构的EEP中,有407只小熊猫:177.228.2只(♂♂.♀♀.??)。EEP的发展经历了40多年的阶段,从繁殖成功率低、死亡率高的小熊猫种群,到繁殖成功率高、与原位保护直接相关的广受欢迎的繁殖计划。然而,仍然存在需要解决的挑战,例如平均亲属关系和遗传多样性,气候变化及其对青少年死亡率的影响,以及长期单身群体中的个人福利。强调这些问题是为了鼓励未来对这一物种的保护进行研究,并给出了动物园可以做些什么来找到解决最紧迫挑战的办法的一些指示。

The development of the Red panda Ailurus fulgens EEP: from a failing captive population to a stable population that provides effective support to in situ conservation

The Red panda Ailurus fulgens is an Endangered small carnivore that occurs in Bhutan, India, Myanmar, Nepal and the People's Republic of China. Wild populations of Red pandas have declined by 50% over the last three generations as a result of habitat loss and fragmentation, hunting and poaching. In 1979 an international studbook was established for the species to monitor the demographically small and unstable population in human care. At that time the breeding results were poor. In 1985 a European Endangered Species Programme (EEP) was initiated and from then onwards the Red panda population started to grow as improved breeding techniques were utilized. As at 31 December 2019 there were 407 Red pandas: 177.228.2 (♂♂.♀♀.??) in the EEP housed at 182 institutions. The EEP developed in stages over four decades, from a small population of Red pandas with low breeding success and high mortality, to a popular breeding programme with high breeding success and direct links to in situ conservation. However, there are still challenges that need to be addressed, such as mean kinship and genetic diversity, climate change and its effects on juvenile mortality, and the welfare of individuals housed in long-term bachelor groups. These issues are highlighted to encourage future research into the conservation of this species with some indications given of what zoos can do to find solutions to the most-pressing challenges.
