评估狮子存在和数量的实地技术回顾
自20世纪90年代以来,非洲国家的狮子(Panthera leo)数量下降了约43%。可靠的狮子数量估计有助于有效的管理,并为当地和国际保护政策提供信息。虽然许多调查方法被用来估计狮子的数量,但缺乏对它们的有用性和有效性的评估。我们回顾并确定了用于估计狮子种群的可用方法,然后调查了它们的可行性、成本效益和实现主要目标的适用性。我们确定了12种方法,分为两类:直接(最小计数,呼叫调查,捕获-再捕获,机会性目击,远程摄像机,基于距离和空中计数)和间接(跟踪计数,次要信息,基于猎物,遗传样本和咆哮计数)。我们确定了48项研究(57%),其中狮子种群估计是不可重复的。此外,38%的人没有提供任何精度测量。大约28%的研究是专门为管理目的而进行的,而其余的研究则侧重于人口估计和动态。由于这些研究的数据影响了当地的狮子管理和全球的狮子保护政策,我们建议未来的政策和管理建立在可重复的、精确的和准确的种群估计基础上,并由适当的和具有成本效益的实验设计支持。在大多数情况下,这些估计是通过直接观察方法获得的实际狮子数量获得的,这些方法包括呼叫、捕获-再捕获和远程摄像机调查,或者通过可靠的动物迹象,如基因样本。

期刊介绍: Mammal Review is the official scientific periodical of the Mammal Society, and covers all aspects of mammalian biology and ecology, including behavioural ecology, biogeography, conservation, ecology, ethology, evolution, genetics, human ecology, management, morphology, and taxonomy. We publish Reviews drawing together information from various sources in the public domain for a new synthesis or analysis of mammalian biology; Predictive Reviews using quantitative models to provide insights into mammalian biology; Perspectives presenting original views on any aspect of mammalian biology; Comments in response to papers published in Mammal Review; and Short Communications describing new findings or methods in mammalian biology.
