Identifying the individuals within a population can generate information on life history parameters, generate input data for conservation models, and highlight behavioural traits that may affect management decisions and error or bias within census methods. Individual animals can be discriminated by features of their vocalisations. This vocal individuality can be utilised as an alternative marking technique in situations where the marks are difficult to detect or animals are sensitive to disturbance. Vocal individuality can also be used in cases were the capture and handling of an animal is either logistically or ethically problematic. Many studies have suggested that vocal individuality can be used to count and monitor populations over time; however, few have explicitly tested the method in this role. In this review we discuss methods for extracting individuality information from vocalisations and techniques for using this to count and monitor populations over time. We present case studies in birds where vocal individuality has been applied to conservation and we discuss its role in mammals.
识别种群中的个体可以生成有关生活史参数的信息，为保护模型生成输入数据，并突出可能影响管理决策以及普查方法中的误差或偏差的行为特征。个体动物可以通过其发声特征来区分。在标记难以检测或动物对干扰敏感的情况下，这种声音个体性可以用作一种替代标记技术。在动物的捕获和处理在后勤或伦理上存在问题的情况下，声音个体性也可以使用。许多研究表明，声音个体性可用于长期计数和监测种群；然而，很少有研究明确测试该方法在这方面的作用。在本综述中，我们讨论了从发声中提取个体性信息的方法以及长期使用此信息计数和监测种群的技术。我们展示了鸟类中声音个体性已应用于保护的案例研究，并讨论了其在哺乳动物中的作用。
