对濒危物种死亡率的调查可以指导保护工作。埃塞俄比亚狼（Canis simensis）是世界上最稀有的犬科动物，现存约1500只。在埃塞俄比亚东南部的贝尔山脉国家公园（BMNP）发现了最大的种群，在那里的保护工作已经证明了狂犬病病毒对狼种群的负面影响。我们描述了2005-2006年和2010年期间这些狼中先前未报告的犬瘟热病毒（CDV）感染。受影响亚群的死亡率范围为43%至68%，亚成年狼的死亡率高于成年狼（83%-87%与34%-39%）。2010年CDV爆发开始于狂犬病爆发后20个月，在人口完全恢复之前，并导致BMNP的Web Valley的几个焦点包被根除。狂犬病和CDV的综合影响增加了狼群灭绝的机会，加剧了狼种群通常缓慢的恢复，并对这种高度濒危的食肉动物种群构成了关键的灭绝威胁。
Investigation into mortalities within endangered species can direct conservation efforts. The Ethiopian wolf (Canis simensis) is the world’s rarest canid; ≈500 wolves remain. The largest population is found within the Bale Mountains National Park (BMNP) in southeastern Ethiopia, where conservation efforts have demonstrated the negative effect of rabies virus on wolf populations. We describe previously unreported infections with canine distemper virus (CDV) among these wolves during 2005–2006 and 2010. Death rates ranged from 43% to 68% in affected subpopulations and were higher for subadult than adult wolves (83%–87% vs. 34%–39%). The 2010 CDV outbreak started 20 months after a rabies outbreak, before the population had fully recovered, and led to the eradication of several focal packs in BMNP’s Web Valley. The combined effect of rabies and CDV increases the chance of pack extinction, exacerbating the typically slow recovery of wolf populations, and represents a key extinction threat to populations of this highly endangered carnivore.
