The Kangaroo Island dunnart (Sminthopsis aitkeni) is a critically endangered marsupial species with an estimated population of ~ 500 individuals found only on the western end of Australia's third largest island. Severe bushfires recently burnt more than 98% of its known and predicted habitat that was already under pressure from fragmentation. After the fires, we found evidence of eight individual dunnarts in the digestive tract of seven feral cats, out of the 86 collected in remaining unburnt refugia; thus demonstrating the need of immediate risk management efforts after large-scale stochastic events.
袋鼠岛囊鼠(Sminthopsis aitkeni)是一种极度濒危的有袋目物种,估计种群数量约为 500 只,仅分布在澳大利亚第三大岛的西端。最近的严重丛林大火烧毁了其已知和预测栖息地的 98%以上,而这些栖息地已经受到了碎片化的压力。火灾后,我们在 86 只收集于未燃烧避难所的样本中,发现了 7 只野猫消化道中有 8 只囊鼠个体的证据;这表明在大规模随机事件后,需要立即进行风险管理工作。
